Against the backdrop of industrial transformation driven by the digital economy, China's equipment manufacturing industry is undergoing a critical transition—from traditional manufacturing to intelligent manufacturing, and from factor-driven growth to innovation-driven development.With the rapid advancement of new-generation information technologies, digitalization, networking, and intelligence have become the core driving forces behind the high-quality development of the manufacturing sector. Confronted with mounting pressures from energy constraints, environmental regulations, and intensified industrial competition, the value-creation model of equipment manufacturing enterprises urgently requires restructuring, with collaborative innovation emerging as a key pathway for sustainable transformation.Centered on the theme of “Collaborative Innovation of Enterprise Value in the Equipment Manufacturing Industry under the Digital Economy,” this study builds upon China’s industrial policies and digital economy strategies, integrating the Resource-Based View, Market Orientation Theory, and Dynamic Capabilities Theory to systematically examine the multi-level relationships among digital transformation, technological innovation investment, green innovation, supply chain flexibility, and corporate sustainable development. Through theoretical analysis, model construction, and empirical testing, this study aims to reveal how technological innovation investment drives improvements in innovation efficiency, value chain restructuring, and the collaborative leap toward sustainable development in the equipment manufacturing sector, thereby providing verifiable theoretical support and policy implications for the digital governance and high-quality development of China’s equipment manufacturing industry. On the theoretical level, this study establishes a supporting framework for collaborative innovation based on three foundational theories.First, the Resource-Based View emphasizes the scarcity and inimitability of internal resources, arguing that data resources, knowledge capital, and innovation capability constitute the core sources of competitive advantage for firms in the digital economy era. Second, Market Orientation Theory elucidates how firms adapt to changing external environments and dynamic market demands, highlighting the need to enhance market sensing and responsiveness through digital means to achieve demand-driven innovation.Finally, the Dynamic Capabilities Theory underscores an organization’s ability to learn, reconfigure, and realign its resources in rapidly changing environments, which is essential for maintaining innovation vitality and competitive advantage under digital conditions. Building on these theories, this study constructs a multidimensional relational model—linking digital transformation, technological innovation investment, green innovation, sustainable development, and enterprise value—and further incorporates contingency management and supply chain flexibility as moderating variables. This framework reveals how firms in complex and dynamic environments develop sustainable innovation capabilities through optimal resource allocation and organizational collaboration. This theoretical framework provides a systematic explanatory foundation for analyzing the innovation leap of equipment manufacturing enterprises in the context of the digital economy. Methodologically, this study adopts a dual analytical approach that integrates quantitative and empirical analyses. First, Chapter 4 employs survey data and applies the SmartPLS structural equation modeling technique to systematically examine the relationships among digital transformation, technological innovation investment, supply chain flexibility, contingency management, and sustainable development. The sample consists of 234 equipment manufacturing enterprises, covering multiple subsectors including general equipment, specialized equipment, electrical machinery, and transportation equipment manufacturing. The results indicate that digital transformation exerts a significant positive effect on sustainable development, with technological innovation investment serving as a partial mediator. Moreover, both supply chain flexibility and contingency management have significant moderating effects on the relationship between technological innovation investment and sustainable development, suggesting that firms with higher environmental adaptability and supply chain flexibility achieve stronger sustainable innovation performance.Second, Chapter 5 conducts an empirical analysis of the dynamic relationship between technological innovation investment and firm value using a two-way fixed effects model, based on 7,520 panel observations from A-share listed equipment manufacturing companies in Shanghai and Shenzhen from 2008 to 2023. The empirical results show that technological innovation investment significantly enhances firm value, while green innovation plays a partial mediating role, indicating that green innovation constitutes a critical pathway through which technological innovation contributes to long-term firm performance. In addition, management expenses and corporate governance capability exhibit stable moderating effects, suggesting that a higher level of internal governance strengthens the transmission mechanism between innovation investment and value creation. This dual-model analytical approach not only verifies the robustness of the theoretical hypotheses but also uncovers the complex interactions among corporate innovation capability, governance structure, and sustainable development. Building upon theoretical integration and empirical validation, this study further develops the SFIC evolutionary model of collaborative innovation in the equipment manufacturing industry under the digital economy context. The model elucidates the formation mechanisms and evolutionary pathways of collaborative innovation:In the initial stage, collaborative motivation arises from asymmetries in resource, power, and knowledge distribution, while inter-firm commitment and mutual trust determine the quality of the starting point for collaborative innovation. During the process stage, institutional design and facilitative leadership jointly shape the collaborative process. Government policy guidance, industrial association coordination, and the leadership of key enterprises through the “chain-head” mechanism together constitute the external driving forces of collaborative innovation. In the outcome stage, technological innovation investment promotes enterprise value enhancement and sustainable performance improvement through the dual pathways of digital transformation and green innovation, ultimately achieving the “leap effect” of collaborative innovation. The findings indicate that the realization of collaborative innovation in the equipment manufacturing industry is not a single-dimensional technological advancement, but rather an integrated evolutionary process encompassing digitalization, greening, and institutionalization.The external policy environment and internal resource endowments form a coupled relationship, driving firms to evolve from partial collaboration toward systemic collaboration, and from static innovation toward dynamic coevolution. Based on the empirical findings, this study proposes a series of multi-level strategic recommendations. First, at the internal level, firms should strengthen data-driven resource allocation systems, establish R&D collaboration mechanisms based on digital platforms, and promote the construction of an intelligent R&D model characterized by “perception–capture–reconfiguration,” thereby enhancing the precision and responsiveness of innovation. Second, firms should optimize their corporate governance structures and build flexible supply chain systems. Through intelligent manufacturing and information-sharing platforms, they can achieve multi-node connectivity and enhance organizational adaptability and learning capacity. At the external level, facilitative policies and regulatory instruments should be improved to establish industry-wide data standards and collaborative governance frameworks, thereby promoting platform-based management of industrial chains and mechanisms for mutual data recognition. Government authorities should foster an industrial collaboration system centered on the “chain-head” mechanism, establish an incentive structure of “co-creation, co-responsibility, and co-sharing,” and strengthen the embeddedness and participation of small and medium-sized enterprises within collaborative innovation networks.
