3.1. Theoretical Background
From the above, it can be seen that there are still points that have been scantly addressed in previous research on CSV activities. One is that the effects on social value have not been analyzed, and the other is that the factors that contribute to the difference in the performance impact of activities have not been sufficiently verified. In order to overcome these problems, two hypotheses were constructed from an integrated approach considering resource dependence theory and stakeholder theory. As resource dependence theory has a slight weakness in terms of how providing resources can lead to the success of firms (Branco and Rodrigues, 2006 [
31]), we believe that we can analyze which kind of CSV activities create corporate value for various kinds of stakeholders by integrating these two approaches.
Through CSV activities, stakeholders not only actively support a company’s business objectives, products, and services, but also provide resources and are involved in the process of creating social value (Corporate and Social Forum, 2013 [
32]). In order to implement and continue CSV activities, firms also invest in organizations through such means as corporate governance and utilization of human resources. For this reason, CSV activities can improve social and corporate value; however, in the short term the cost of providing resources must come first.
In addition, differences in the content of CSV activities by industry can be explained, to a certain extent, in terms of the availability of management resources. For example, compared to product-related CSV activities, CSV activities related to the value chain often indirectly invest management resources to raise the income of suppliers and others, and investment in product development, production, and sales is considered to be small. As the ratio of product- to value chain-related CSV activities differs depending on the industry, these differences are thought to create differences in the impact on corporate value.
Second, the effectiveness of CSV activities also affects how stakeholders perceive and take an interest in them. A company’s CSV activities function as signals to each stakeholder, through communication and other means, which improve the company’s reputation and image, thereby improving business performance.
Many scholars believe that cognitive capabilities play a vital role in creating shared value (Corner and Pavlovich, 2016 [
27]; Lee, 2019 [
28]) and that interactions have important significance in its formation. When interactions with stakeholders are promoted through investments in corporate governance, utilization of human resources, etc., the enhancement of corporate image is expected to lead to higher corporate value over the long term, for example by fostering employee awareness to make it easier to create interactions and reforming corporate governance. In addition, the affected stakeholders also have different characteristics, depending on the industry, such as general consumers and business partners. In other words, the communication strategy differs greatly between BtoB (Business to Business) and BtoC approaches. However, it is difficult to strictly distinguish between BtoB and BtoC for each company and, as many companies handle both BtoB and BtoC, industry categories based on goods classification are considered in this study. In other words, the industrial categories of lifestyle-related industries, assembly industries, and materials industries, in that order, are closer to consumers, and differences in communication strategies and activities are expected to affect their performance. In this way, the impact on corporate value through CSV activities, which lead to the following two hypotheses, can be best explained through an integrated approach based on resource dependence theory and stakeholder theory.
3.2. Study Framework
From previous research, it can be asserted that CSV investments have a positive relationship with financial performance. For example, Fernández-Gámez et al. [
18] showed that hotels that invest in socially responsible initiatives can generate a shared value between tourism firms and their stakeholders, which has a positive impact on financial performance. However, belonging to a group had a moderating effect, which tended to strengthen the association between CSV activities and financial performance. In other words, the effects of CSV were independent of hotel size, market segment, and star rating, recognizing that the outcomes of CSV strategies do not depend on the characteristics of their establishments alone, as the positive effects of CSV strategies have been verified in all of the organizational environments of the hotel industry.
To the contrary, as our sample comprised manufacturing industries, different results may be shown. As we assume that commercializing the development of products takes a long time, when CSV activities related to R&D are carried out these activities may not generate short-term profits.
Furthermore, among Japanese firms, there are many CSV activities that are conducted for purposes other than profit, such as donations (Takata and Ohno, 2021 [
33]).
Through their activities, Japanese firms tend to invest in corporate governance and personnel system reforms; these investments will generate long-term profits, but not short-term profits. Therefore, the following hypothesis was derived.
Hypothesis 1. CSV activities by Japanese firms do not contribute to short-term financial performance, but have an improving effect on social value indicators.
Next, as Benedikt argued, each industry differs in terms of what Porter and Kramer [
1] denoted as the three categories of CSV activities that firms are likely to apply. As the effect of each activity differs depending on whether its content is related to the product or the value chain, it is considered that CSV related to products and CSV related to value chains differ in terms of the resources provided by companies and stakeholders. Differences in these classification ratios by industry sector will manifest as differences in the impact on corporate and social values through resource contributions.
Secondly, we assume that communication strategies differ between the material industry—where BtoB (Business to Business) elements are strong—and in assembly and lifestyle-related industries—where BtoC (Business to Consumers) elements are strong.
This may lead to differences in how stakeholders perceive activities, which may affect the reputation of the company by stakeholders and manifest as differences in the impact on corporate value and other factors. In this regard, Takata and Ohno [
33] pointed out that the purposes of activities also differ depending on the industry, as well as the ratio of attitudes toward profits (e.g., whether certain activities are making sufficient profits or are regarded as future business opportunities). Of course, different attitudes toward profit not only lead to differences in financial performance, but also differences in the impact on investments to improve social value (e.g., reforming human resource systems and corporate governance), depending on whether the activity is viewed as a long- or short-term investment. This leads to the following hypothesis:
Hypothesis 2. Corporate value, social value, and factors that influence them differ, depending on the manufacturing sector.
In this study, we focus on three factors (See
Figure 1): relationship with the management strategy (in terms of product strategy and communication strategy), the company profile, and the influence of the differences between industries. As the targets of CSV activities by Japanese firms are mainly for Japanese markets [
18], we assume that the influence of these factors is larger than that of the market differences.
In terms of the company profile, the environmental factors of industries and enterprises are taken into account by considering the sales growth and changes in the environment. By considering the growth potential of sales, it is possible to consider the size of the enterprise while taking into account the latest changes in sales. The latest sales growth rate is correlated with an improvement in business performance and, if the growth potential of a firm is high, then the ROA change value is also expected to be high. Furthermore, by considering the fluctuation of sales in the industry, it is possible to consider the business environment differences in the industry. If the environment changes greatly, it is assumed that it will exert pressure on firms to change, thus leading to changes in corporate governance that improve social value, as well as affecting corporate performance. In addition, environmental sensitivity is a dichotomous variable that can be used to identify firms whose activities involve higher environmental risk (Branco and Rodrigues, 2000 [
30]). Firms operating in the chemical, paper, and steel areas are assigned a value of 1, while other firms assume a value of 0 for this variable. Furthermore, to distinguish sensitivity to consumers, BtoB and BtoC were distinguished within industries, with BtoC being 1 and BtoB being 0.
Regarding the product strategy, we focus on the existence of core business and the classification of Porter and Kramer [
1]. First, we consider diversification by focusing on the presence of core businesses. We assume that with a core business, the degree to which the product’s business environment affects corporate performance is significant, and consumers are expected to infer whether a company is serious about its activities based on whether the CSV activities are related to its core business. Second, we consider how Porter and Kramer defined CSV activities as activities organized for three purposes—products, value chains, and cluster creation—and how these have positive influences on social and organizational benefits. Among activities, few fall under the category of cluster creation. Compared to the impact of CSV activities related to products, CSV activities related to the value chain require a certain period of time to lead to improvements in profitability, such that profitability is unlikely to be affected in the short term. Takata and Ohno also pointed out that the closer the activity is to the business, the higher the importance of corporate value [
33].
Regarding the communication strategy, we analyze the relationship between materiality and internal communication. Materiality denotes important issues related to firms and, by evaluating and prioritizing the degree of impact of corporate activities on social issues, the manner in which important firms recognize each issue can be made clear. In addition, it is thought that sharing CSR activities within firms and developing employees with specialized knowledge makes it easier to improve corporate profits, even if the CSV activities are implemented in specific departments and external communication and materiality are set up. From this point of view, we consider internal branding elements.
Furthermore, we distinguish between CSV activities related to products and those related to the value chain, as the effects on financial performance and social value differ according to the type of strategy. We consider three industrial categories—assembly industry, material industry, and lifestyle-related industry—and analyze the factors for each.
3.4. Multi-Level Analysis
If the dependent variable of case
i belonging to group
j is
, the independent variable is
, and the error is
, the intercept and regression coefficient common to group
j can be written as follows:
where the coefficients are the intercept and regression coefficients common to group
j, which are called the fixed effects. Next, a model is used to express that these are probabilistically scattered in each group, centered on a certain value:
where
is the overall average of
(i.e., the intercept),
represents the error for each group,
represents the overall average of the slope, and
denotes the error for each group. Furthermore, by replacing the overall mean with the intercept of the group (i.e.,
), the regression coefficient for each group (i.e.,
), and the independent variable,
, the final regression equation can be written as follows:
The parts in parentheses in the equation are elements of random effects, which differ from group to group.
3.5. Regression Model
Based on the conceptual diagrams and research methods discussed in
Section 3.1,
Section 3.2 and
Section 3.3, the following regression models are presented as verification models. From the methodological point of view of empirical analysis, the elements observed in almost all of the firms in the target sample were not adopted as variables, even if they were closely related to CSV activities; for example, a management philosophy that leads to improved corporate value in the medium- to long-term, making it an important element for CSV activities, was established in 94.5% of the manufacturing industry samples in the CSR survey.
Similarly, risk management efforts are also related to the materiality setting and are closely related to CSV activities, but 87.9% of the CSR survey samples in the manufacturing industry reported building a risk management system. Furthermore, 84.2% of the firms had implemented a basic policy and, if the firms implementing this CSV activity are used in the sample, then the ratio will be even higher [
4].
Equations (1)–(3) are regression equations that use the change values of human resource utilization, corporate governance, and sociality scores, respectively, which are social evaluation values for which the change values are significant as explanatory variables. In Equations (1–3), CHSL denotes the corporate growth rate YOY between 2019 and 2021; CHEV is the coefficient of variation of the industrial average of sales (average of industrial sales/the standard deviation of industrial sales); PROD and VALUE are dummy variables, which take a value of 1 if the contents of CSV activities correspond to CSV activities related to products and the value chain, respectively; CORE is a dummy variable, which takes a value of 1 if there is a main business with a 75% share (i.e., a core business); MATER is a dummy variable, which takes a value of 1 if a firm has materiality; INTBR is a dummy variable, which takes a value of 1 if firms conduct training related to the SDGs or if information on the SDGs and sustainability is shared internally; EVSEN indicates industries with a high sensitivity to environmental initiatives (paper-, steel-, and chemical-related industries fall into this category; if a respondent falls into one of these industries, it takes the value of 1; otherwise, it takes the value of 0); COSEN represents the sensitivity to consumers, and after observing the business composition, we took 1 for BtoC (Business to Consumer) firms and 0 for BtoB (Business to Business) firms. HMSC, CGSC, and SCSC represent the figures for human resource utilization, corporate governance, and sociality scores in 2019, respectively.
Equation (4) is a regression equation in which the change of ROA value is used as an explanatory variable.
