中国数字经济与制造业绿色发展耦合协调研究OACHSSCDCSTPCD

Based on the coupling mechanism of digital economy and green development of manufacturing industry,this paper constructs an evaluation index system.Firstly,the paper measures the development level of digital economy and the green devel-opment level of manufacturing industry in 30 provinces of China from 2013 to 2021 by using the entropy weight method,then dis-cusses the spatial-temporal evolution characteristics of digital economy and green development of manufacturing industry by using the coupling coordination model,and finally applies the obstacle degree model to analyze the obstacle factors in the coupling coor-dination process,and also empirically analyzes the influencing factors of their coupling coordination.The research finds that there exists a strong coupling interaction between China's digital economy and the green development of manufacturing industry,the coupling coordination degree on the rise,but the overall level is not high and imbalanced,and that the digital economy and the green development of manufacturing industry is positively affected by the level of economic development,government participation and urbanization development.
