Mechanism,Evaluation and Enlightenment of the Coupling and Coordinated Development of Digital Economy and Producer Services
The research on the coupling and coordinated development of digital economy and producer services has im-portant theoretical and practical significance.On the basis of exploring the internal mechanism of their coupling coordination,this paper constructs an evaluation index system and uses coupling coordination degree,Theil Index and kernel density estima-tion method to evaluate and analyze the integration coordination degree,regional differences and dynamic changes of China's digital economy and producer services.The results show that the coupling coordination degree of digital economy and produc-er services in most regions is at a moderate level,and the coupling coordination degree of digital economy and producer services is significantly different in different regions,and the coupling coordination degree of digital economy and producer services in provinces and cities has a certain gradient effect.Based on this,it is proposed that we should deeply promote the integrated de-velopment of digital economy and producer services,focus on improving the coupling and coordinated development level of digital economy and producer services in the region,and effectively strengthen the linkage of the coupling and coordinated de-velopment of digital economy and producer services in the region.
