1. Introduction
Recently, the rapid development of the construction market has fueled economic growth, while simultaneously revealing issues such as extensive management and product homogenization [
1,
2]. These challenges have emerged as major obstacles to the sustainable development of many construction enterprises. Recognizing that relying solely on existing product technology limits market share growth and fails to meet changing customer needs, construction enterprises are increasingly aware that competitive advantages can only be achieved by increasing service innovation for existing product technology [
3]. Meanwhile, the global construction industry has been severely impacted by the COVID-19 pandemic since late 2019. Governments, industries, and academia have all been actively exploring strategies to address this crisis. The industry is still steadily recovering from continued ongoing efforts [
4]. Nevertheless, the post-pandemic era has ushered in a market environment characterized by volatility, uncertainty, complexity, and ambiguity. This dynamic environment is commonly referred to with the acronym VUCA [
5]. In this VUCA era, enterprises must leverage innovation to establish novel driving forces for maintaining a sustainable competitive advantage [
6]. This indicates that driving innovation and transforming from traditional construction contractors into comprehensive service providers has become an inevitable trend for construction enterprises to achieve sustainable development. These comprehensive service providers are able to provide holistic solutions that encompass investment and financing, planning, design, construction, operation, and maintenance [
7]. Thus, construction enterprises must focus on the efficiencies and effectiveness derived from engaging in service innovation activities, or what we call service innovation performance (SIP). It is imperative for these enterprises to urgently identify effective approaches to enhance SIP.
Existing research posits that digital transformation (DIT) serves as an emerging means for construction enterprises seeking a competitive edge in the digital economy era [
8]. Concurrently, service innovation is recognized as a crucial competitive advantage that construction enterprises aspire to uphold [
7]. DIT, when effectively implemented, has the potential to optimize and facilitate service innovation activities, leading to enhanced performance outcomes. Despite the acknowledged impact of DIT on financial performance [
9,
10], innovation performance [
11,
12], and new product development performance [
13,
14], limited attention has been given to its effects on SIP [
15]. Moreover, current research on DIT predominantly focuses on traditional industries, manufacturing, and service sectors, leaving the DIT of the construction industry in its early development stages. This is evidenced by the McKinsey report, which shows that the global construction industry ranks second to last in digitization levels, only above agriculture [
16]. Given this context, there is substantial theoretical and practical value in investigating the relationship between DIT and SIP in construction enterprises. Simultaneously, enterprises grapple with the challenge of balancing the utilization of existing resources and capabilities while establishing new ones that align with the evolving path brought about by DIT [
11,
17]. Dual innovation (DI), as referring to two distinct innovation methods that flexibly leverage enterprise resources and capabilities, emerges as a critical mechanism for effectively navigating the DIT dilemma. This approach aids in generating positive SIP outcomes through the synergy of both established and newly acquired capabilities. Building upon previous research, this study focuses on Chinese construction enterprises as the survey subjects, and employs DI as the mediating variable, exploring the mechanisms by which DIT shapes SIP.
The next section reviews the literature on the DIT, DI, and SIP.
Section 3 proposes the research hypotheses.
Section 4 introduces the research methods.
Section 5 presents the obtained results.
Section 6 summarizes the study’s main contributions and further discusses some valuable results. The final section outlines key findings, management insights, and also highlights the study’s main limitations along with potential future research directions.
3. Research Hypothesis
3.1. Relationship between DIT and SIP
The Resource-Based View posits that an enterprise’s unique resources and capabilities are critical in gaining a competitive advantage in the market [
47]. This perspective is particularly relevant to construction enterprises, where DIT is essential for restructuring production and operational processes, as well as organizational structures. In doing so, it fosters the development of distinct resources and capabilities, thereby enhancing SIP. Despite its obvious relevance, the current literature is scarce in directly exploring the relationship between DIT and SIP in construction enterprises. Most studies focused on the broader impact of DIT on overall enterprise performance. For instance, the research conducted by Li and Jia demonstrates how DIT significantly improves product quality, optimizes sales channels, and fosters innovative business models. Collectively, these factors contribute to both the expansion of market share and the enhancement of enterprise performance [
48]. Similarly, Abou-Foul et al. emphasize the positive impact of digitization on financial performance, noting that prioritizing service delivery during the digitization process can yield even greater financial benefits [
49]. Conversely, a minority of scholars contend that digital technologies may induce conflicts between production and management systems, potentially diminishing enterprise performance [
50].
The synthesis of the current research indicates a consensus among the majority of scholars that DIT exerts a positive impact on enterprise performance. This effect is particularly pronounced in construction enterprises where SIP—a type of enterprise performance triggered by service innovation activities—is also influenced by DIT. The essence of DIT aims to achieve customer value propositions and enhance value addition through a comprehensive upgrade of the business process. Meanwhile, the essence of service innovation resides in the development of new service products driven by customer needs. DIT acts as a catalyst for service innovation activities, which, when executed effectively, yield tangible performance gains. Drawing on these insights, the following hypothesis is proposed:
H1. DIT positively affects SIP.
3.2. Relationship between DIT and DI
During the process of DIT, the widespread application of digital technology has accelerated the flow, aggregation, and sharing of both internal and external resources, which enables enterprises to rapidly acquire and utilize market information, capture market opportunities, and engage in both ERI and EII [
51]. When enterprises find themselves caught in the “dilemma” of DIT, they require digital empowerment to enhance their dual capabilities [
52,
53]. The exploitation capability formed through digital empowerment can enable enterprises to refine and expand existing capabilities and technology paradigms, aiding in optimizing existing business processes, and consequently improving efficiency. Given that path dependence hinders enterprises from undertaking innovative activities, the exploration capabilities gained through digital empowerment can assist in reducing path dependence, reshaping business models, and promoting breakthrough achievements in disruptive innovation.
Likewise, DIT is a pivotal tool for the flexible redistribution and utilization of resources among construction enterprises. It facilitates the restructuring and integration of complementary internal and external resources, thereby offering potential for both ERI and EII. During the transformation process, these enterprises can expand their product and technology scope. This expansion is driven by a keen awareness of the latest industry trends and market demands, coupled with the development of new products and services, creating fertile ground for ERI. Simultaneously, this process accelerates the transfer and sharing of resources across internal and external boundaries. It aids in consolidating and refining existing knowledge and skills, enhancing current products and services. This, in turn, motivates enterprises to pursue EII activities more vigorously. Based on these observations, the following hypotheses are proposed:
H2a. DIT positively affects ERI.
H2b. DIT positively affects EII.
3.3. Relationship between DI and SIP
This study begins with an examination of the relationship between DI and enterprise performance, an area with limited existing research directly addressing the connection. Focusing on DI and enterprise performance, research has shown that ERI significantly impacts enterprise performance, particularly under the moderating effect of competitive intensity. This observation is supported by survey data from China’s semiconductor and pharmaceutical industries [
54]. However, contrasting findings emerge when considering Hong Kong’s manufacturing enterprises, where it appears that only EII significantly and positively affects enterprise performance [
55]. Providing an additional viewpoint, Osiyevskyy et al. found that distressed enterprises could enhance performance through both ERI and EII. This suggests that enterprise success relies on both exploiting existing and exploring new markets, knowledge, and skills [
56].
The complex relationship between DI and enterprise performance remains a focal point for scholarly inquiry, inspiring deep contemplation and exploration. SIP, a type of enterprise performance, is directly influenced by DI, a critical tool for enhancing enterprise performance. In the context of construction enterprises, ERI plays a crucial role. It leverages new resources and capabilities to develop innovative products and services, and to explore new markets, thus enlarging the enterprise’s market share and boosting its SIP. Simultaneously, EII enables these enterprises to more effectively integrate existing resources and capabilities. By improving current products and services to more aptly suit the existing market, it further elevates the enterprise’s SIP. Building on this understanding, the following hypotheses are proposed:
H3a. ERI positively affects SIP.
H3b. EII positively affects SIP.
3.4. Mediating Effect of DI
DI is an effective strategy for addressing the “dilemma” faced by enterprises during DIT. It is also a crucial tool for attaining a competitive advantage and consistent success. An empirical analysis of Chinese manufacturing enterprises conducted by Su et al. demonstrated that DI serves as an indirect mediator between big data analysis capabilities and organizational performance [
57]. Thus, this study suggests that DI provides an indirect transmission path in the DIT process, thereby influencing the SIP of construction enterprises. Additionally, DIT acts as a catalyst for two distinct types of innovative activities.
In the era of the digital economy, construction enterprises embark on DIT to adapt to the intricate and ever-changing market environment, thus securing a competitive edge. Successful DIT enables these enterprises to rapidly acquire and integrate information related to customer groups, upstream suppliers, and stakeholder enterprises. This enhances their ability to discern market opportunities and achieve precise market positioning. Furthermore, DIT empowers construction enterprises to efficiently integrate both internal and external resources through digital technology and other methods. This strategic allocation of limited resources to these two categories of innovative activities maximizes resource utilization value and fosters active engagement in DI. In this context, ERI is instrumental in creating new products and services and venturing into new markets to secure long-term competitive advantages. Simultaneously, EII focuses on refining existing products and services to align with current market demands, thereby maintaining the enterprise’s market position [
27]. Collectively, these two innovative activities are pivotal in driving the continuous and stable growth of SIP. On this basis, the following hypotheses are proposed:
H4a. ERI mediates between DIT and SIP.
H4b. EII mediates between DIT and SIP.
Based on the above hypotheses, a theoretical model in this study is proposed, as shown in
Figure 1.
6. Discussion
Currently, research on DIT within the construction industry context remains relatively scarce. For construction enterprises, DIT serves as a crucial means to address challenges such as extensive management practices and severe product homogeneity. It is also an essential step towards enhancing their digitization level. Consequently, this study, focusing on construction enterprises, aims to broaden the scope of DIT research. Moreover, the impacts and mechanisms of DIT on SIP in the construction sector are remain thoroughly unexplored. Addressing this, our central research question delves into how construction enterprises can boost their SIP through DIT. Meanwhile, the study introduces DI as a pivotal mediating variable. This allows for a deeper examination of the interaction mechanisms between DIT and SIP, thus enriching the empirical research on service innovation driven by DIT.
Utilizing the SEM, this study successfully validated all seven proposed hypotheses. The following discussion centers on two principal outcomes derived from these validations.
Hypothesis H1 establishes a positive correlation between DIT and SIP, suggesting that DIT not only optimizes but also promotes service innovation activities. This result yields performance gains, equipping enterprises to navigate a complex and evolving market environment while meeting increasing customer demands. This finding aligns with Ferreira et al. [
15], further enriching the body of research on the economic impacts of DIT. In their current phase of extensive development, construction enterprises are focusing on both service innovation and DIT simultaneously. Service innovation has emerged as a key strategy for gaining competitive advantages, while DIT provides the necessary technological support and a strong impetus for service innovation. This dual approach not only boosts internal efficiency and reduces operational costs but also motivates enterprises to continuously strengthen their core competitiveness and market positioning.
Hypotheses H4a and H4b examine the mediating role of DI in bridging DIT and SIP. The results reveal that DIT fosters both ERI and EII, thus providing support for service innovation. These results correspond with Su et al. [
57], thereby broadening the scope of research on DI outcomes. Currently, a significant challenge for construction enterprises undergoing DIT lies in balancing the use of existing resources and capabilities while integrating new ones that align with their historical development trajectories. This highlights a crucial task for managers: overcoming resource constraints and further enhancing organizational capabilities amidst DIT. DI, characterized by its distinct innovation activities that flexibly utilize enterprise resources and capabilities, emerges as an essential mechanism. It effectively addresses the dilemmas of DIT in enterprises, thus playing a pivotal role in elevating SIP.
In summary, the research results presented above provide a novel perspective for construction enterprises aiming to boost their SIP in the digital economy era.
7. Conclusions
7.1. Key Findings
This study develops a theoretical mechanism model elucidating how construction enterprises can enhance their SIP through DIT in the era of the digital economy and innovation-driven development. Employing SEM and the Bootstrap method, this research investigates the impact of DIT on SIP within construction enterprises, further examining the mediating roles of both ERI and EII. This study yields the following key conclusions:
Firstly, the DIT of construction enterprises significantly contributes to enhancing SIP. This transformation, akin to SIP, is fundamentally customer-centric. This shared focus on customer needs positions DIT as a vital driver in elevating SIP. Guided by the principle of customer value, DIT can reshape customer advocacy, streamline internal production and operational processes, and elevate service quality and customer experience. It empowers enterprises to meet customer needs more flexibly and offer more personalized, customized solutions. This extensive impact not only bolsters the core competitiveness of enterprises but also aids in expanding their market share, securing sustainable competitive advantages in a highly competitive landscape. Consequently, the positive influence of DIT on SIP is multidimensional, encompassing the refinement of internal processes as well as the differentiation and innovative enhancement of external services. DIT transcends mere technological change, it is a strategic move that propels enterprises toward maximizing customer value.
Secondly, both ERI and EII serve as partial mediators in the nexus between DIT and SIP. During DIT, construction enterprises employ tools such as digital technology not only to acquire new resources and knowledge but also to integrate existing ones. This synergy in resource utilization enables them to respond more agilely to market fluctuations, thereby enhancing the vitality of service innovation. In this context, ERI underscores the enterprise’s capacity to develop new resources and knowledge. DIT facilitates broader channels for information acquisition, enabling enterprises to timely grasp market trends, customer demands, and industry developments. Leveraging this information, they can more effectively develop new products and services to meet emerging market needs. Concurrently, EII focuses on the enterprise’s ability to amalgamate existing resources and knowledge. Through DIT, enterprises can more effectively harness internal information, experiences, and technologies. This integration aids in flexibly enhancing the quality of current products and services, aligning with existing market requirements. Therefore, ERI and EII collectively constitute a critical mediating mechanism in how DIT influences the SIP of construction enterprises. This mechanism provides substantial support for enterprises striving for competitive superiority in an increasingly complex market landscape.
7.2. Management Enlightenment
Derived from the research conclusions outlined earlier, this study has formulated two critical managerial insights:
Firstly, actively promoting and executing DIT remains of paramount importance. Construction enterprises can use digital platforms and a variety of resources to actively promote the DIT of the enterprise, so as to provide support for service innovation. In the evolving digital landscape, it is essential for these enterprises to prioritize financial investment, as DIT necessitates substantial financial resources. The effectiveness of financial investment is key to realizing the various aspects of DIT. Moreover, elevating the application level of digital technology is critical. Enterprises should stay attuned to the latest digital technology trends in the industry and flexibly employ these technologies to refine their production and operational processes. Effective use of digital technologies facilitates the rapid and accurate acquisition of data, thereby enhancing strategic decision making. Equally important is the development of digital talent. Construction enterprises must emphasize nurturing and recruiting individuals with digital skills, which are essential for driving the successful application of digital technology and ensuring the quality and effectiveness of the DIT. By embracing DIT, enterprises can achieve information sharing and visualization, improve organizational operational efficiency and resource allocation, as well as continually upgrade the quality of their products and services. This transformation not only enhances the corporate image and attracts customers but also significantly elevates SIP.
Secondly, it is crucial for construction enterprises to actively engage in DI activities during DIT, thereby improving their service innovation capabilities. The core lies in the pursuit of synergistic development of both ERI and EII, which can effectively adapt to dynamic market changes. Therefore, during the DIT, construction enterprises should flexibly mobilize existing resources through digital means to improve their existing products and services. For instance, employing BIM technology for project management can better serve current customers and markets. Meanwhile, it is acknowledged that DIT cannot be achieved overnight. Senior managers are required to possess exceptional strategic resilience and foresight, coupled with the courage to break away from their path dependence, to foster organizational change and reshape business models. Digital means can help enterprises identify new market opportunities and develop new digital products and services. For example, developing customized software for specific construction projects can provide more personalized solutions. Next, it is vital for enterprises to provide greater organizational support to employees, thus stimulating their innovative potential through digital skills training and the sharing of successful experiences. Additionally, the current global investment in technology for the construction industry constitutes less than 1% of total revenue [
16]. Hence, providing support at both the industry and government levels to encourage innovative activities in enterprises is of equal importance. Industry organizations can facilitate the dissemination of advanced knowledge and skills by conducting training sessions and seminars, thus supplying enterprises with high-quality talent. Governments can encourage enterprises to engage in technological research and development activities by implementing tax break policies and offering financial support. Naturally, different countries should adopt tailored strategies to encourage enterprise innovation activities, aligned with their local development conditions. Overall, by implementing a DI strategy, construction enterprises can not only maintain flexibility and adaptability in DIT but also enhance their SIP and strengthen their competitiveness in the ever-changing market environment.
7.3. Limitations and Future Prospects
Despite its contributions to both theoretical and practical domains, this research is not without its limitations. Firstly, while it establishes DI as a key intermediary mechanism through which DIT enhances SIP in construction enterprises, it is possible that alternative pathways between DIT and SIP exist. Future studies should investigate other possible mediating mechanisms and examine the moderating effects within various contexts. Secondly, the study focuses on Chinese construction enterprises, drawing its sample data exclusively from China. This geographic specificity means that the findings are particularly relevant to Chinese construction enterprises, but could potentially limit their generalizability. Comparative studies with data from other countries could broaden the research scope in future investigations. Thirdly, this study employs cross-sectional data, which fails to account for the influence of time-related changes on the research outcomes. To further strengthen the validity of the relationships between variables, future research could incorporate longitudinal survey data, capturing the nuances of temporal variations. Lastly, future research could also consider conducting an objective statistical analysis of the construction industry from the perspective of the application of innovations and digital technologies and compare them with the research conducted in this paper.
