Higher education and digital Economy: Analysis of their coupling coordination with the Yangtze River economic Belt in China as the example

Abstract

Analyzing the coupling coordination interactions of higher education (HE) and digital economy (DE) to achieve sustainable growth is crucial. Thus, we constructed the coupling coordination interaction mechanism and the comprehensive evaluation system of the two subsystems to measure their coordination interactions; then, we processed the temporal-spatial analysis of the development status and the coupling coordination degree (CCD) in the case of China. Furthermore, we used the gray correlation model to determine the primary influencing factors and proposed differentiated policymaking suggestions. We found that: (1) the development status of higher education (HE-D) was more stable than that of the digital economy (DE-D), which showed a slight upward trend; besides, there were noticeable spatial differences for HE-D and DE-D. (2) The temporal changes of CCD were not noticeable. (3) Expenditure on research activities in HE and the number of patents were the significant factors affecting DE; the popularity rate of mobile phones and the number of employees in the DE industry were the significant factors affecting HE; besides, HE's output benefits and DE's input was more influential in the coordination relations. Furthermore, we also put forward targeted, specific, and differentiated policymaking suggestions, which can guide policymakers to formulate regional sustainable development policies.
