A Study on the Effect of Change Management on Organizational Innovation: Focusing on the Mediating Effect of Members’ Innovative Behavior

: This study is an empirical study on the impact of change management on organizational innovation through innovative behavior in the public sector. The independent variables are the four elements of change management (organizational goal, transformational leadership, participation and communication, education and training), the dependent variable is organizational innovation, and the mediating variable is the innovative behavior of members. The data used for the analysis is the Public Service Recognition Survey 2018 by KIPA (the Korea Institute of Public Administration). Hayes’ Process Macro analysis (Model 4) was performed to verify the mediating variable. As a result of the analysis, it was found that change management factors have a positive effect on innovative behavior and organizational innovation. In addition, public ofﬁcials’ innovative behavior played a mediating role between change management and organizational innovation. It was conﬁrmed that the innovative behavior of organizational members is essential to achieve organizational innovation. Among the factors of change management, participation and communication had the highest inﬂuence on innovative behavior and organizational innovation.


Introduction
At the World Economic Forum (WEF), Klaus Schwab emphasized the 4th industrial revolution and described the 4th industrial revolution as "a combination of physical, digital, and bio technologies in new and diverse ways". It was defined as "an unstoppable shift towards a much more complex form". This can be seen as a revolution that changes everything as a completely different form beyond the 3rd industrial revolution, which was aimed at simple digitalization [1]. In order to know the competencies required by an organization in this era, the characteristics of the 4th industrial revolution must be grasped first, and the word that best describes the 4th industrial revolution is VUCA. VUCA is a concept derived from the acronym of a word that expresses four characteristics: Volatility, Uncertainty, Complexity, and Ambiguity. In other words, the environment in which organizations are adapting to the era of the 4th industrial revolution is characterized by the rapid speed of change and the wide range of changes, as well as the complex and ambiguous state and results of such change, making it difficult to define [2]. Therefore, the 4th industrial revolution, which has such characteristics, requires all organizations to make more radical changes than the changes that have been made so far, and organizations can be cut off from competition if they do not respond to such changes. Therefore, various modern organizations are implementing innovation as a response strategy for a dynamically changing environment. Public organizations are no exception to the subject of innovation, and they must adapt to the changing environment and lead the industry to increase performance. In the recent era of the 4th industrial revolution, various organizations are trying to survive in the era of the 4th industrial revolution by using ICT technologies such as big data, robots, blockchain, cloud, artificial intelligence, Internet of Things, and virtual augmented reality in the existing traditional work methods. It is striving for innovation. Public organizations are also actively promoting innovation to respond to the rapidly changing environment in the era of the 4th industrial revolution and improve performance. However, members of the organization can be resistant to change and innovation due to lack of trust, obsession with past successes, distrust of change strategies, relatively high expenditures, threats to value and accidents, and refusal to interfere. Organizations need change management to overcome these resistances and to successfully innovate [3][4][5][6][7][8][9][10][11][12][13][14][15]. Therefore, the rapid environmental change in the era of the 4th industrial revolution may be a crisis for organizations that are not ready for change, but for organizations that can actively respond to environmental changes, such environmental change can be an opportunity for a new leap forward. An organization's ability to respond to environmental changes begins with the innovative behavior of organizational members. In order to achieve organizational innovation, the innovative behavior of an organizational member is very important. The purpose of this study is to examine the importance of organizational members' innovative behavior in the relationship between change management and organizational innovation.
This work is organized as follows: after the introduction Section 1, we present a literature review of the concepts and relationships of organizational innovation, innovative behavior, and change management Section 2. Then, we introduce the methodology Section 3 and describe the findings and discussion Section 4. Lastly, we summarize the findings, present policy implications, and conclude Section 5 [16].

Literature Review
This study aims to examine whether the innovative behavior of the members of public organizations is influenced by change management factors such as organizational goals, transformational leadership, participation and communication, and education and training. Additionally, it seeks to analyze whether innovative behaviors facilitate organizational innovation. To conduct the analyses, we first review the literature related to the theoretical definition of each variable and the relationship between the variables.
Bozeman frequently mentioned the differences between private and public organizations [17][18][19]. However, a study by Bozeman and Kingsley (1998) [20] noted that there was no significant difference in organizational innovation between private and public organizations. Therefore, in this study, we would like to conduct a prior study analysis, including the private sector.

Organizational Innovation
Organizational innovation stands for the radical and fundamental transformation of an organization to an improved state through planned change. An organization is an open system that constantly interacts with the environment. Therefore, organizational innovation is inevitable for one that seeks to adapt to environmental changes. Organizational innovation is a planned change that is guided by a certain value standard, and it is a dynamic and relevant change. The representative definition of organizational innovation is as follows. Damanpour (1991) [21] sees the adoption of innovation as innovation and defines it as including the creation, development, and execution of new ideas and actions. Therefore, organizational innovation is defined as the creation or purchase of new devices, systems, policies, programs, processes, products, and services in an organization. Jones (2010) [22] argues that organizational innovation refers to the process of moving to a future organizational state better than the present in order to increase organizational effectiveness. In addition, the goal of organizational innovation was defined as finding ways to improve the resources, capabilities, and competencies that will be used to achieve organizational goals. Lastly, Demircioglu (2016) [23] mentions that organizational innovation can be defined as the introduction of something new (an idea, product, service, technology, process, and strategy) to an organization. In summary, organizational innovation can be defined as a process that fundamentally promotes the intentional and planned change of the organization through its creation, introduction, and application of new ideas, objectives, and tools. The application of behavioral science has become essential in the process of organizational innovation, so as to facilitate the study of organizational diagnosis, its window, catalyst, application process, and training of members.

Innovative Behavior
Innovative behavior is defined as the process of solving a problem, presenting a solution through knowledge or new ideas from experience, supporting the idea, and realizing the idea to promote the organization's interests [16]. Several scholars have defined various kinds of innovative behaviors. West and Farr (1990) [24] defined it as behavior designed to intentionally introduce and apply new ideas and procedures within groups and organizations in order to improve their performance. Van de Ven (1986) [25] defined it as the creation and execution of new ideas within human relationships over a long period of time. Katz and Kahn (1978) [26] asserted that innovative behavior involves developing or realizing ideas and non-role behavior, whereas Kanter (1988) [27] defined it as products, services, processes, etc. provided by the supporters of creative ideas. Amabile (1998) [28] posited innovation as the process of selecting creative ideas and introducing them to product processes. Thus, innovative behavior can be summarized as the process of adopting creative ideas that are presented or developed by individuals or groups and turning them into useful resources. It is an action that ultimately improves job performance by introducing and improving job skills that alter the work process in an efficient way [17][18][19][20].

Change Management
Change management is an activity that enables members to participate in change effortlessly while simultaneously subduing their shock and resistance to the process of change. It is said that change is the law of nature and is different from the familiar. However, the humans prefer the familiarity and convenience, and this inertia prevents them from changing their current habits. The factors that inhibit organizational change are mainly organizational inertia, traditional culture, the successful approximate response strategies learned in the past, the cost of driving transformation, and conscious/unconscious resistance by organizations. In general, change commences when the factors that facilitate change prevail over the factors to inhibit change. Brown and Morberg (1986) [4] defined planned organizational change as the process of changing the sub-levels of the organizational system-namely the organizational climate, technology, structure, decision-making process, and management system--to achieve organizational goals. Levy (1988) [29] defined change as a wide and multidimensional phenomenon that transforms the organizational paradigm itself beyond the level of piecemeal improvement, and the process of change was modeled as a stage of change in such factors as triggering change, planned change strategies and techniques, confusion process, and paradigm. Greiner (1972) [30] found that the most commonly used strategies for change are leadership, communication among members, and education and training to help stakeholders to implement new concepts, behaviors, skills, and techniques in a new management system. He also stated that there may be participation of all members of the organization, reinforcement for continuity, and counseling to individually resolve causes of resistance that are from outside the organization. Kotter and Schlesinger (1979) [31] asserted that education, participation and communication, specialty and support, negotiations and agreements, manipulation and cooperation, and explicit/implicit coercion are crucial ways to manage resistance to change. In summary, several methods are used for change management, and these methods affect many organizations both directly and indirectly. To this end, we will examine the specific change management promotion plans by setting organizational goals, transformational leadership, participation and communication, and education and training as key factors. Recent research on change management has focused on methodologies to effectively man-age the resistance of individuals who are impeded for organizational innovation and promoting innovative behavior. We start from Lewin's research, which is the initial study of change management, and it examines changes in the behavioral patterns of individuals (changes to improve the ability of individuals to adapt to the organization within the organization). In other words, research has been conducted focusing on management methods to minimize individual resistance, and such research trends have continued until recently. Change management, which is commonly defined in recent change management research, is defined as intentionally changing the behavior and perception of members so that they can achieve target performance by preventing or eliminating members' resistance to change. In addition, studies have been mainly conducted to minimize resistance from members when promoting innovation. Looking at the preceding studies on the main factors of change management, Greiner (1972) [30] mentioned leadership, communication among members of the organization, education and training, participation of members, and counseling as major factors. Kettinger and Grover (1995) [7] organized the main factors of change management into communication, direct member participation, role playing, and training. Voelpel et al. (2004) [32] mentioned effective leadership, education and training, clear strategies, inter-level communication, and mutual cooperation among members. Whelan-Berry and Somerville (2010) [33] mentioned vision, leader behavior, communication, education and training, employee engagement, personnel systems/practices, and organizational structure. Based on these preceding studies, this study intends to define the factors of change management into four categories: organizational goal, leadership, participation and communication, and education and training. Table 1 below shows the Preceding studies for Component of change management.

Organizational Goal
An organizational goal represents the desired state of the organization. The organizational goal provides a direction for organizational activities and serves as a social force that substantially impacts current activities. An organizational goal also provides the basis for the organization's legality and legitimacy, the organization's standards of action, guidelines for decision-making, and criteria for evaluating the organization's effectiveness [73]. In addition, an organizational goal does not remain the same but rather changes over time. An organizational goal is constantly transforming and growing or disappearing due to changes in the external environment and occasionally due to internal contradictions or structural forces. Organizations undergo transformations in accordance with these changes in organizational goals.

Transformational Leadership
The transformational leadership theory presented by Burns in 1978 was formulated by Bass in 1985 to fit the organizational context. Burns (1978) [74] mentioned that transfor-mational leadership promotes organizational enthusiasm and facilitates the acceptance of the organizational mission, which enables the organization's interests to be placed before that of the individual. Bass (1985) [75] defined transformational leadership as motivating members of the organization to achieve organizational needs and offer solutions to problems (Matt Bi, 2013). The definitions of other scholars who have studied transformational leadership are as follows. Kuhnert and Lewis (1987) [76] noted that transformational leadership drives organizational trust and improves organizational performance through stimulation and consideration. Conger (1999) [77] defined transformational leadership as motivating members of the organization to work and perform beyond expectations and emphasizing higher-order needs. In summary, leaders can be defined as transformational leaders if they present the organizational vision to members and positively change member of the organization through smooth interaction with the members.

Participation and Communication
Participation and communication are factors that must be considered simultaneously. Participation is the process through which members of the organization exercise influence and control in the administrative and decision-making process. Therefore, in order for members to participate, communication must occur. Communication is a significantly diverse concept, but if the various definitions offered by researchers are combined, communication stands for the transmission of people's thoughts and meanings with one another. The word communication is derived from the Latin noun "communis," which means common, communality, or sharing. Therefore, in order for such communication to take place, the participation of the subject is essential. A place for participation should be prepared so that information and opinions can be exchanged between the members of an organization. If participation does not occur, it is difficult to communicate in the first place. Such participation and communication are complementary. By sharing information through participation and communication, members can achieve common goals.

Education and Training
Education and training are a planned activity that improves the knowledge and skills of the members of the organization, which enables them to adapt to the organization and perform their duties effectively in pursuit of the organization's goal [78]. Noe (1986) [79] mentioned that education and training is a planned learning experience and is an activity that transforms personal knowledge, skills, and attitudes. Cascio and Award (1981) [80] defined it as a process of acquiring the requisite skills and knowledge to match the demands of a job. Beach (1980) [81] defined education and training as learning the knowledge and skills necessary to achieve the goal. Anthony et al. (1999) [82] defined it as the development of the knowledge, skills, qualities, and behaviors required to improve job performance and competency and facilitate the career development of organizational members. To be more specific, education refers to long-term activities that comprehensively develop an individual's potential, whereas training represents short-term activities of supplementation [83]. However, many scholars have stated that the theoretical distinction between education and training has no distinct advantage for public officials. This is because public officials require both long-term and short-term capabilities to provide better administrative services [84]. Therefore, the integrated concept of "education and training" has been used in previous literature.

Change Management and Innovative Behavior
According to Locke's goal-setting theory, a goal is set by individuals to consciously influence motivation and behavior. Locke (1968) [85] highlighted that an established goal has an influence on human motivation and behavior, which explains why several studies have been conducted on goal-setting. Loke and Latham (1990Latham ( , 2006 [86,87] noted that an established goal determines the level of individual effort, provides the basis for motiva-tion, and ultimately affects organizational behavior. The relationship between goal and behavior can be similarly applied to organizational goals and innovative behavior. Many studies have stated that the clarity of an organizational goal or members' perception of an organizational goal has a positive effect on innovative behavior [34,44,[88][89][90][91][92][93][94][95]. However, Kim et al. (2019) [96] analyzed the relationship between clarity of an organizational goal and innovative behavior by studying 2000 public officials at the central government, and the results of the analysis were different for managers and non-managers. For non-managers of grade 5 or lower, it had a positive impact on innovative behavior, whereas for managers of grade 4 and higher, it had no significant impact on innovative behavior.
Transformational leaders present a vision for the future to constituent members of the organization, provide intellectual stimulus so that members of the organization can escape from past customs, and provide support in the process of change accompanied by pain, which makes it possible for members to participate in change. Therefore, it is expected that such a transformational leader will be able to increase the innovative behavior of members of the organization. In order to verify this through prior studies, a number of studies have shown that the perception of the superiors' transformational leadership has a positive effect on innovative behavior. The studies that mentioned the relationship between transformational leadership and innovative behavior are as follows. Burnside (1990) [97] noted that positive encouragement and support from leaders has a positive effect on creative behavioral responses and performance. Scott and Bruce (1994) [98] highlighted that innovative behavior is facilitated by leadership support, trust, and providing subordinates with the autonomy to generate creative ideas. Ryu and Yoo (2008) [99] analyzed the relationship between transformational leadership and innovative behavior among 52 public organizations and noted that transformational leadership has a positive impact on innovative behavior. Previous studies on the relationship between transformational leadership and innovative behavior have indicated that transformational leadership positively affects innovative behavior [34,50,53,54,[100][101][102][103][104][105].
Organizational members have an interactive relationship with one another and are not merely independent subjects. The organizational atmosphere in which various members of the organization can participate in the decision-making process and communicate freely can promote the innovative behavior of the organization members. In order to innovate continuous work practices and avoid inertia, it is possible to promote the innovative behavior of members of the organization by collecting various opinions of members of the organization and developing creative ideas that have been previously conceived. Lin's (2007) [106] study mentioned that smooth communication between members affects personal innovative behavior. A study by Damanpour (1991) [21] noted that the stronger the communication among members within an organization, the better their innovative behavior. There have been many prior studies that have shown that participation has a positive effect on innovative behavior [16,34,58,[106][107][108][109]. There have also been a number of studies that illustrate that communication has a positive effect on innovative behavior [51,58,60,61,106,110]. Therefore, if participation and communication are facilitated, the members begin to exchange ideas about the direction of the organization's future development, which will result in improved innovative behavior.
Education and training can strengthen the capacity of organizational members and respond to rapidly changing environments. Accordingly, public organizations differ to varying degrees in terms of their functions and goals, but each has their own education and training program. Through education and training, each organization cultivates the human resources needed to create administrative and public services, strives to foster talent within the organization, strengthens their job capabilities, and promotes cooperation and harmony among them. The ability to change the behavior of each member can be enhanced through the development of these abilities. Previous studies on the relationship between education and training and innovative behavior have indicated that education and training positively affect innovative behavior [111][112][113][114][115][116]. However, Lee et al. (2019) [117] analyzed the impact of education and training on innovative behavior by public officials' grade and found that the impact of education and training on the innovative behavior of public officials of grade 1 to 4 was not significant. However, it was analyzed that education and training have a positive impact on innovative behavior for public officials of grade 5 to 9.

Change Management and Organizational Innovation
Previous studies found that the organizational goal has a positive effect on organizational innovation. Meroño-Cerdán and López-Nicolás (2017) [39] noted that organizational goals related to innovation have a significant influence on the adoption of organizational innovation. The results mentioned that the organizational mission promotes organizational innovation. Razavi and Attarnezhad (2013) [45] mentioned as a result of researching previous literature that an organizational vision is a way to promote organizational innovation. It was mentioned that the shared organizational vision has a positive effect on organizational innovation. McDonald's (2007) [44] study analyzed the relationship between organizational missions and organizational innovation for non-profit organizations and noted that there is an indirect significant effect between organizational missions and organizational innovation, and Brooks-Rooney et al. (1987) [118] also emphasized that organizational vision is a major factor in determining the type and degree of organizational innovation. In addition, a number of other studies have corroborated the positive effect of organizational goal on organizational innovation [34,39,[44][45][46][90][91][92][93][94][95][96]118,119].
In order to succeed in organizational innovation, the organizational leader must be able to clearly and convincingly present the necessity of innovation and the future state of the organization in which the innovation was made, that is, the vision [120]. In addition, leaders must induce feelings of loyalty, trust, and respect in the members of the organization so that they can elicit higher-than-expected efforts and achieve results through changes in attitudes and values. Looking at the relationship between transformational leadership and organizational innovation, most of the preceding studies mention that transformational leadership has a positive effect on organizational innovation, and representative studies related to this are as follows. Jung et al. (2003) [50] noted that transformational leadership has a positive impact on organizational innovation by influencing the perception of organization members about empowerment and innovation in a supportive atmosphere. Gumusluoglu and Ilsev's (2007) [51] study noted that transformational leadership consists of charismatic role modeling, personal consideration, inspirational motivation, and intellectual stimulation, and transformational leadership has a positive impact on organizational innovation. In addition, a number of other studies have corroborated the positive effect of transformational leadership on organizational innovation [34,[52][53][54]59,106,110,[121][122][123][124][125][126][127][128].
This study mainly focused on research that indicated that participation and communication have a positive effect on organizational innovation. Having analyzed the relationship between communication and organizational innovation, Monge et al. (1992) [57] highlighted that communication has a significant effect on organizational innovation. Kivimak et al.  [60] noted that communication has a significant effect on organizational innovation, and a study by Chun (2006) [129] stated that public officials' participation is the most important factor in the techniques for achieving innovation in government organizations. Several other studies have also found that participation and communication have a positive effect on organizational innovation [16,34,36,[56][57][58][59][62][63][64][65][66][67]106,109,[130][131][132][133].
Previous studies have found that education and training have a positive effect on organizational innovation. Garcia-Morales et al. (2008) [46] examined the relationship between organizational learning and organizational innovation and outlined that the former has a significant effect on the latter. Hussain et al. (2013) [69] highlighted that organizational learning has a significant positive relationship with organizational innovation, thereby illustrating the significance of education and training for organizational innovation. Sev-eral other studies have also demonstrated the positive effect of education and training on organizational innovation [60,70,71,[133][134][135][136][137].

Innovative Behavior and Organizational Innovation
Innovative behavior starts from the individual and spreads to the organization. Therefore, for organizational innovation, it is necessary to search for the factors that induce innovation within individuals and create an environment in which they can express their innovativeness [138]. Jiang et al.'s (2012) [62] study indicated that human resource management (HRM) has a positive effect on employee creativity, which in turn has a positive effect on organizational innovation. Gmusluoglu and Ilsev (2009) [51] noted that transformational leadership positively affects both individual creativity and organizational innovation but that individual creativity does not affect organizational innovation. Glynn (1996) [139] presented a framework regarding the intellectual ability of individuals and organizations to innovate. According to the framework, individual creativity influences organizational innovation. Peters (2014) [140] indicated that innovation-focused HR awareness affects employees' innovative behavior, which ultimately influences organizational innovation. In addition, many other studies have demonstrated that innovative behavior has a positive effect on organizational innovation [141][142][143][144][145][146][147][148][149].

Research Framework
The framework of this study is as follows. Organizational innovation was set as the independent variable. Organizational goal, transformational leadership, participation and communication, and education and training were set as the independent variables. The control variables were sociological and demographic factors (gender, age, educational background, employment period, position, affiliation), work characteristics factors (providing work resources, work autonomy, work performance capabilities), and organizational culture factors (group culture, development culture, hierarchical culture, rational culture), which were organized through the analysis of previous studies. In this study, we examined whether change management factors directly affects organizational innovation or whether it does so indirectly through the innovative behaviors of members. First, we investigated the influence of change management factors on the innovative behavior of the members of an organization. Second, we studied how change management factors affect organizational innovation. Third, we explored whether public officials' innovative behavior mediates the relationship between change management and organizational innovation. Figure 1 below shows the research framework of this study.

Research Questions and Hypotheses
Previously, research was conducted on how organizational goals, transformational leadership, participation and communication, and education and training independently

Research Questions and Hypotheses
Previously, research was conducted on how organizational goals, transformational leadership, participation and communication, and education and training independently influence innovative behavior or organizational innovation. Unlike prior research, this study comprehensively analyzed how change management factors for innovation collectively affect the innovative behavior of public officials and ultimately influences organizational innovation. In accordance with this problem consciousness, this study devised three research questions. First, studies analyzing the relationship between change management factors and innovative behavior have indicated that change management factors have a positive effect on innovative behavior [36,44,56,95,[98][99][100][101]110,[130][131][132]150]. Thus, the research question obtained through the literature review is as follows. Third, many studies have highlighted that change management factors have a positive effect on innovative behavior [36,44,56,95,[98][99][100][101]110,[130][131][132]150]. In addition, previous studies mentioned that the members' innovative behavior affects their organizational innovation [51,62,[141][142][143][144][145][146][147][148][149]152,153]. Thus, the research question obtained through the literature review is as follows.

Research Question 3. Does innovative behavior have a mediating effect on the relationship between change management factors and organizational innovation?
Research Hypothesis 3. Innovative behavior will mediate the relationship between change management factors (organizational goal, transformational leadership, participation and communication, education and training) and organizational innovation.
Research Hypothesis 3-1. Innovative behavior will mediate the relationship between an organizational goal and organizational innovation.

Research Hypothesis 3-2.
Innovative behavior will mediate the relationship between transformational leadership and organizational innovation.

Research Hypothesis 3-3. Innovative behavior will mediate the relationship between participation and communication and organizational innovation.
Research Hypothesis 3-4. Innovative behavior will mediate the relationship between education and training and organizational innovation.

Variables and Measurement
This study utilized survey data to empirically examine how change management factors have an impact on innovative behavior and, consequently, organizational innovation. Research has been conducted on the influential factors with respect to governmental innovation to analyze the effect of the majority on the innovative behavior of organizational members. However, since government innovation resembles organizational innovation, empirical research on the factors influencing organizational innovation is needed. Therefore, this study intends to examine the effects of change management factors on innovative behavior and organizational innovation. The components and measurement methods of independent variables, mediating variables, dependent variables, and control variables that are required to examine the impact are as follows. First, an exploratory factor analysis was performed on the change management factors, which are independent variables. The analysis facilitated the identification of four factors: organizational goal, transformational leadership, participation and communication, and education and training. Organizational goal was measured using a 5-point Likert scale for four questions related to it. Transformational leadership was measured using a 5-point Likert scale on the four questions related to it. In addition, seven questions related to participation and communication and three questions related to education and training were measured using a 5-point Likert scale. Second, innovative behavior--which is the mediating variable--was measured using a 5-point Likert scale for two questions related to it, and factor analysis was conducted on two questions. Third, organizational innovation--a dependent variable--was measured using a 5-point Likert scale for three questions related to it, and factor analysis was performed on three questions. Fourth, the control variables consisted of sociological and demographic factors, work characteristics factors, and organizational culture factors. The sociological and demographic factors were organized into gender, age, educational background, employment period, position, affiliation, and employment type. The work characteristics factors were organized by into provision of work resources, work autonomy, and work performance capabilities. [Appendix A] shows information about detailed variable measurements.

Analysis Method and Data
In this study, we used Hayes' Process Macro to verify the mediating effects between variables. Usually, mediating effects can be analyzed by regression analysis and structural equation modeling (SEM). The Process Macro technique proposed by Hayes (2013) [154] is a new regression that can compensate for the disadvantages of the existing mediating effects analysis method of Baron and Kenny (1986) [155], Sobel Test (1982) [156], and structural equation modeling. Baron and Kenny's (1986) [155] mediating effect verification method has been criticized for indirectly predicting it through three-step causal reasoning, which does not directly verify the mediating effect. In addition, the Sobel test for measuring the magnitude of mediating effects assumes the normality of the sample distribution when verifying the significance [157,158]. On the other hand, SEM analysis has the advantage of using confidence intervals through free and verifiable bootstrapping under normal distribution assumptions [158]. However, unlike regression analysis, SEM also has the disadvantage of using only continuous variables. The Process Macro introduced by Hayes (2013) [154] can directly infer the magnitude of mediating effects through bootstrapping and has the advantage of conducting a regression analysis without assuming a normal distribution. Therefore, many existing studies at home and abroad use Process Macro as a mediating effect analysis method [53,151,[159][160][161][162][163][164][165][166]. This study measures the mediating effect of innovative behavior in the relationship between change management and organizational innovation using Hayes' Process Macro [154]. In this study, we used the "Model = 4" process macro.
This study uses the Public Employee Perception Survey Data 2018 from the Korea Institute of Public Administration (This article makes use of research material produced by the Korea Institute of Public Administration (KIPA), and it has been authorized for use according to KIPA's regulations on the ownership and the use of said research material.). The independent variables, mediating variables, dependent variables, and control variables used in this study were all measured through Public Employee Perception Survey Data 2018. A total of 4000 people were surveyed via email. Sampling was conducted through probability samples for public officials belonging to 46 central government departments and 17 regional governments in Korea. The survey period is one year from 1 August 2017 to 31 July 2018, and the survey was conducted from August to September 2018. These data are nationally approval statistics data approved by statistics Korea in 2018.

Validity and Reliability Analysis
In this study, exploratory factor analysis and reliability analysis were performed to test the validity and reliability of measurements. In the factor analysis, a principal component factor analysis was performed using the Varimax rotation, which is a rightangle rotation with Kaiser rule. In the reliability analysis, reliability was analyzed by the internal consistency method that calculates the Cronbach's alpha coefficient (Lim et al., 2016). First, the factor analysis on the change management factors established the feasibility of measuring organizational goal, transformational leadership, participation and communication, and education and training as factors. The Cronbach's alpha coefficient was 0.877 for organizational goal, 0.916 for participation and communication, 0.936 for transformational leadership, and 0.799 for education and training. Table 3 below shows the analysis results.  Second, the factor analysis on the measure of the work characteristics factors established the validity of measuring provision of work performance resources, work autonomy, and work performance capability as factors. The Cronbach's alpha coefficient was 0.801 for provision of work performance resources, 0.787 for work autonomy, and 0.747 for work performance capability to establish reliability for measuring as factors. Table 4 below shows the analysis results. Third, the factor analysis on the measure of the organizational culture factors established the feasibility of measuring rational culture, development culture, group culture, and hierarchical culture as factors. The Cronbach's alpha coefficient was 0.757 for rational culture, 0.811 for development culture, 0.812 for group culture, and 0.757 for hierarchical culture to establish reliability for measuring as factors.

In order to examine the relationship between change management and organizational innovation and how public officials' innovative behavior mediates the relationship between the two, a mediation-regression analysis was conducted through the fourth Hayes' Process Macro model. Table 6 is the result of the mediating effect verification that utilized Hayes' Process Macro.   Table 6 shows the total effect of change management factors on innovative behavior and organizational innovation. It was found that organizational goal, transformational leadership, participation and communication, and education and training have a positive effect on both organizational innovation and innovative behavior. Even with respect to the total effect, it was noted that change management factors have a positive effect and that participation and communication has the largest relative impact. A summary of the results of this multiple regression analysis, the direct effects of organizational goal, transformational leadership, participation and communication, training and organizational innovation, and the indirect effects of individual innovation behavior are presented in the following Tables 7-10.    The above Table 7 shows the magnitude and significance of the direct effect of organizational goal on organizational innovation and the indirect effect of members' innovative behavior. The bootstrap confidence interval of the total effect was significant because it did not contain 0, and the magnitude of the effect was 0.2082. The direct effect of an organizational goal on organizational innovation was significant because the bootstrap confidence interval did not include 0, and the magnitude of the effect was 0.2016. In addition, the effect of organizational goal on organizational innovation through the mediation of members' innovative behavior was also significant because the bootstrap confidence interval did not include 0 and the magnitude of the effect was 0.067. Thus, the results revealed that organizational goal primarily directly influences organizational innovation. Table 8 shows the magnitude and significance of the direct effect of transformational leadership on organizational innovation and the indirect effect of members' innovative behavior. The bootstrap confidence interval of the total effect is significant because it did not contain 0, and the magnitude of the effect was 0.2066. The direct effect of transformational leadership on organizational innovation was significant because the bootstrap confidence interval did not include 0, and the magnitude of the effect was 0.2035. In addition, the effect of transformational leadership on organizational innovation through the mediating effect of members' innovative behavior was significant because the bootstrap confidence interval did not include 0, and the magnitude of the effect was 0.031. Thus, the results revealed that transformational leadership mainly directly influences organizational innovation. Table 9 shows the magnitude and significance of the direct effect of participation and communication on organizational innovation and the indirect effect of members' innovative behavior. The bootstrap confidence interval of the total effect was significant because it did not contain 0, and the magnitude of the effect was 0.5885. Among the total effects, the direct effect of participation and communication on organizational innovation was significant because the bootstrap confidence interval did not contain 0, and the magnitude of the effect was 0.5841. In addition, the effect of participation and communication on organizational innovation through the mediating effect of members' innovative behavior was significant because the bootstrap confidence interval did not contain 0, and the magnitude of the effect was 0.0044. Table 10 shows the magnitude and significance of the direct effect of education and training on organizational innovation and the indirect effect of mediating members' innovative behavior. The bootstrap confidence interval of the total effect was significant because it does not contain 0, and the magnitude of the effect was 0.1233. The direct effect of education and training on organizational innovation was significant because the bootstrap confidence interval did not include 0, and the magnitude of the effect was 0.1175. In addition, the effect of education and training on organizational innovation through the mediating effect of members' innovative behavior was significant because the bootstrap confidence interval does not contain 0, and the magnitude of the effect was 0.0057.

Conclusions
Due to the rapid environmental change in the era of the fourth industrial revolution, the importance of government innovation to cope with it is growing day by day. In this study, we looked at how organizational goal, transformational leadership, education and training, participation, and communication, which are techniques for change management, are affecting government organizational innovation. It also looked at the instrumental role of public officials' innovative behavior in order for the government to adapt to the rapid environment. The analysis results of the relationship between change management, innovative behavior, and organizational innovation are summarized as follows.
First, recognition of an organizational goal was found to have a positive effect on both organizational members' innovation behavior and organizational innovation.
Second, it was found that the perception of transformational leadership had a positive effect on both the organizational members' innovative behavior and organizational innovation.
Third, participation and communication were found to have a positive effect on both the innovation behavior and organizational innovation of the organization members.
Fourth, it was found that education and training had a positive effect on both the organizational members' innovation behavior and organizational innovation.
Fifth, organizational members' innovation behavior mediated the relationship between change management (organizational goal, transformational leadership, participation and communication, education and training) and organizational innovation.
Effective change management (organizational goal, transformational leadership, education training, participation and communication) for public organizations can change the characteristics of members' implementation of change and ultimately achieve organizational innovation. Conversely, if change management activities are not carried out effectively, members will be more immune to change, increasing their critical tendency to change, and increasing performance through future changes will be more difficult. The policy implications that this study would like to highlight are as follows.
First, change management is very important in order to effectively drive the innovative behavior of organizational members. Change management can achieve not only the innovative behavior of organizational members but also ultimately organizational innovation.
Second, we found that innovative behavior is an important parameter that mediates between change management and organizational innovation. The innovative behavior of organizational members is essential in a rapidly changing environment. Members of a public organization must take into account the importance of innovative behavior and implement it.
Third, the magnitude of the impact of participation and communication on innovative behavior and organizational innovation was relatively large, and the size is much larger than other factors. Therefore, public organizations must recognize and implement the importance of participation and communication.
The findings on the relationship between change management factors, innovative behavior, and organizational innovation in this study are expected to give policy implications in planning and implementing innovation policies (programs) to promote government organizational innovation and innovative behavior. In addition, this study has academic implications in that it empirically verified the effectiveness of change management techniques to promote organizational innovation and innovative behavior.

Limitation of this Study
We analyzed the relationship between change management, innovative behavior, and organizational innovation of government organizations and made theoretical considerations on the direction in which government organizational innovation should proceed through the analysis results. However, this study has a limitation that it failed to discuss the procedural aspects of change management within the organization for organizational change. In addition, conducting analysis with panel data allows us to analyze the relationship between change management, innovative behavior, and organizational innovation in detail, but this study has limitations in data using only 2018 data. Informed Consent Statement: Informed consent was obtained from all subjects involved in the study.
