激励性政策规制推动中国数字经济高质量发展机制研究

Research on Mechanism of Incentive Policy Regulation Contribute to the High-Quality Development of Chinese Digital Economy

基于中国2010—2019年30个省区市的面板数据,采用多期双重差分模型,研究国家政策创新对数字经济高质量发展的影响,考察创新政策的调节效应和中介效应。研究发现,激励性政策规制能够显著促进数字经济高质量发展,在经过平行趋势检验、安慰剂检验以及工具变量估计后,研究结论依然稳健。区位异质性分析发现,激励性政策规制对于政策质量型区域的数字经济发展具有明显的正向促进效应。作用机制检验发现,激励性政策规制对数字经济高质量发展的影响受到创新升级驱动效应、产业结构驱动效应和市场发展驱动效应的调节。在全国层面上和政策质量型区域,激励性政策规制促进数字经济高质量发展可以通过提升知识资本水平实现。

Based on the panel data of 30 provinces in China from 2010 to 2019,a multi-period double difference model is used to study the impact of national policy innovation on the high-quality development of the digital economy.It is found that China's incentive policy regulation can significantly promote the high-quality development of the digital economy,and the research conclusion is still robust after testing and instrumental variable estimation.On this basis,the analysis of location heterogeneity and the testing of the mechanism of action were carried out,and the incentive policy regulation and the high-quality development of China's digital economy were explored at the national level and in the policy quality region.
