A Research on the Empowerment of Digital Economy on High-quality Development of China's Manufacturing Industry Chain
The basic feature of China's economic development in the new era is to change from"high-speed growth"to"high-quality development".Based on panel data from 30 province-level divisions from 2011 to 2020,this paper establishes a comprehensive index system to empirically explore the empowering effect of the digital econ-omy on the high-quality development of China's manufacturing industry chain,and the regional heterogeneity was also investigated.The research shows that the high-quality development level of China's manufacturing industry chain has been on the rise except for the slight decrease in 2012.The digital economy has been developing rapidly with the growth rate exceeding 100％,the effect of digital economy on high-quality development of manufacturing industry chain is"U-shaped",and it is in the significant promotion stage.The effect of the east coast,the south coast,the middle reaches of the Yangtze River and the greater southwest economic zone was"U-shaped",which was consistent with the nationwide effect.The northern coast and the Northwest China Economic Zone showed a lin-ear promotion effect.The effect of the middle reaches of the Yellow River is not significant while that of the north-east is restrained,and there is regional heterogeneity in the high-quality development of the manufacturing chain of the digital economy.China should continue to develop digital economy,coordinate the spatial distribution of digital industry,promote regional digital balance,and further promote the high-quality development of manufacturing in-dustry chain.
