Research on Influencing Factors of Catch-Up in Complex Product Systems: Taking the China Manned Space Engineering Application System as an Example

In the face of escalating global competition in science and technology, complex product systems (CoPS) have emerged as a significant indicator of comprehensive national strength. The exploration of the catch-up phenomenon holds substantial implications for subsequent development of CoPS. Existing CoPS research often focuses on a single engineering task (such as high-speed rail) and market logic (such as the telecommunications industry), examining the catch-up phenomenon from a single or hard-power perspective. However, the China Manned Space Engineering Application System (CMSEAS), with its significant international influence and dual characteristics of scientific research and engineering development, presents a different scenario. Its market value is difficult to be reflected in a short time, making the relevance of existing research limited. This study selected CMSEAS as a case, and acquired data through interviews, internal meetings, on-site observations, official websites, archives, and other forms. Based on grounded theory, open coding, axial coding, selective coding, and a saturation test were carried out, and a catch-up model of CoPS was constructed by considering various influencing factors. The results show that the catch-up is driven by five major factors: support force is the basic condition for its gradual growth; the management system, technical capability, and human resource are interdependent and serve as the direct drivers of the catch-up; and social influence plays a significant role in propelling the catch-up indirectly. Notably, the setup of a general department, interaction among different factors, cultural soft power, and social influence serve as useful complements to previous studies.
