Abstract: As for the transformation and upgrading of manufacturing enterprises, the deep integration of digital resources and physical resources is a key strategic direction and resource base. How to effectively integrate heterogeneous resources between data and reality has become a key issue that urgently needs to be addressed by enterprises. Enterprises not only need to break through the technological bottleneck of integrating digital and physical resources, but also face the challenge of reshaping the relationships among resource stakeholders. Hereto, this paper bears in mind the characteristics of the digital and physical resource integration context and takes the perspective of an ecosystem where leaders and participants interact to look at a typical case of Sany Heavy Industry. It is found that resource integration can be achieved along the evolution path of “product-platform-ecology” through a coupling and collaborative mechanism of “real to virtual” demand integration, “virtual to real” vision driven, and the coupling and collaboration mechanism of “virtual and real linkage”. Firstly, ecological participants integrate market user needs, constructing mathematical models embedded in physical resources, and achieve product intelligence. Secondly, leading enterprises build digital platforms and reconstructing physical resources into project scenarios. Finally, leaders and participants collaborate with each other to establish a secondary sub platform in the niche market, achieving nested and linked ecological intelligence. This paper analyzes the mechanism of the integration process of “digital and physical” resources, expands the research on the interaction of multiple entities in the ecosystems, and provides practical reference for the empowerment and upgrading of enterprise resources.
