Abstract:At present, research on the relationship between technological talents, technological innovation, and economic development mainly focuses on two aspects: impact effects and synergistic effects. In order to deeply reveal the internal connections between the talent chain, innovation chain, and industrial chain in Jiangsu Province, this paper takes the three subsystems of scientific and technological talents, scientific and technological innovation, and economic development as the research object, and constructs a comprehensive system synergy evaluation index system for Jiangsu. Based on data from 2011 to 2020, it uses a composite system static synergy model and a dynamic change comprehensive validity evaluation model to calculate the status and trend of the development level and change rate of each system's synergy. The results show that the static collaboration degree of the integrated system in Jiangsu has increased year by year during the same base period, but has not yet reached the advanced collaboration level; the three subsystems have a synergistic effect with each other, but they have been in a low degree of collaborative evolution for a long time, and the synergistic effect is not stable, among them, the technology talent subsystem is the main factor causing instability; the structure of scientific and technological talents, the number of research institutions, the proportion of the tertiary industry, and the proportion of high-tech enterprises are key factors that affect the coordinated development of the scientific and technological talent subsystem, scientific and technological innovation subsystem, and economic development subsystem, respectively; and the development trend of collaborative speed among various systems shows irregular fluctuations. Based on the above conclusions, it proposes that Jiangsu provincial government should establish mechanisms for promoting effective collaborative development, such as information disclosure, resource sharing, and departmental linkage, strengthen the optimization of talent structure, mobilize the enthusiasm of enterprise research and development to promote the integration and development of talent chain, innovation chain and industrial chain, pay attention to the coordinated development status and speed of various systems, and other countermeasures and suggestions to promote the realization of a collaborative pattern of scientific and technological talents, technological innovation, and economic development.
