摘要
基于2011—2020年31个省份的面板数据,构建双向固定效应模型、调节效应模型、面板门槛模型,全面揭示数字经济赋能制造业高质量发展的机制。研究发现:提升数字经济发展水平有利于促进制造业高质量发展,且促进作用整体呈现出西部>东部>中部地区的特征;数字经济能够通过提升人力资本水平与技术创新水平、降低企业交易成本正向调节对制造业高质量发展的赋能作用;数字经济驱动制造业高质量发展的赋能作用随着研发投入水平、环境规制、人力资本水平的提升呈现“边际收益递增”的特征。
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.
