摘要
在给出数字经济和区域经济协调发展综合水平测度方法的基础上,借助2012-2020年的省级面板数据,采用固定效应模型、分位数回归模型和中介效应模型对数字经济影响区域经济协调发展的效应和机制进行多层面的实证检验.结果表明:数字经济可显著促进区域经济协调发展,但存在地域异质性,对经济协调发展水平较低地区的促进作用更强;数字经济可以通过提高技术创新水平、提升生态环境质量来间接推动区域经济协调发展,且这种中介作用效果显著.
Abstract
Based on introducing the comprehensive level measurement method of the coordinated development of digital economy and regional economy,the paper adopted the provincial panel data from 2012 to 2020,and used the fixed-effect model,quantile regression model and mediating effect model,to conduct a multi-level empirical test on the effects and mechanism of digital economy affecting the coordinated development of regional economy.The results showed that:digital economy could significantly promote the coordinated development of regional economy,while there was regional heterogeneity.The promotion effect was stronger in the regions having a lower level of coordinated regional economic development.In addition,digital economy could further promote the coordinated development through the improvement of technological innovation level and the enhancement of ecological environment quality,and the intermediary regulation effect was remarkable.
