Research on the Assessment and Drivers of the Coupling Coordination Development between Green Innovation and Digital Economy
摘要
The study evaluates the coupling coordination degree between digital economy (DE) and green innovation (GI) in Chinese provinces from 2013 to 2020, as well as exploring the driving factors affecting the coupling and coordination degree between the two. The findings indicate: (1) The GI level in most provinces of China shows a fluctuating upward trend, with a spatial distribution characterized by higher GI level to the east of the Heihe-Tengchong Line and lower GI level to the west. The overall level of the DE is steadily increasing, with coastal provinces and the Chengdu-Chongqing region leading the trend. (2) The coupling coordination degree between DE and GI in each province has passed the stage of low coupling coordination, and the coupling coordination level between DE and GI has been increasing, with positive spatial spillover effects. (3) The number of invention patents granted, software business revenue, and online retail sales are the main driving factors. Furthermore, the study emphasizes that the synergy between external means, such as government regulation, and internal factors is very important to promote the coordinated development of the DE and GI.
