Mechanism of Digital Economy on High-Quality Development of Manufacturing Industry——An Empirical Study Based on Panel Data of 31 Provinces from 2011 to 2020
Based on the panel data of 31 provinces from 2011 to 2020,this paper constructs a two-way fixed effect model,moderating effect model,and panel threshold model and comprehensively reveals the mechanism of the digital economy enabling high-quality development of the manufacturing industry.Research findings are as follows:First,the improvement of the development level of the digital economy is conducive to promoting the high-quality development of the manufacturing industry.Furthermore,the overall promoting effect shows the characteristics of the western region＞eastern region＞central region.Second,the digital economy can positively moderate the promoting effect on the high-quality development of the manufacturing industry by improving the human capital level,enhancing the technological innovation level,and reducing the transaction cost of enterprises.Third,the influence of the digital economy on the high-quality development of the manufacturing industry shows the characteristics of"increasing marginal revenue"with the improvement of R&D investment level,environmental regulation,and human capital level.
