摘要
本文围绕数字经济对城市经济发展的影响及其异质性分析展开深入研究,基于2011—2020年我国 270 个地级以上城市的数字经济发展水平,构建了检验数字经济发展对经济发展影响的实证模型,并从地理区位、产业结构和经济发展水平三方面展开异质性分析。结果表明:数字经济显著促进了经济发展,在稳健性检验后仍成立。异质性分析方面,数字经济对中部地区的促进作用比东西部地区更显著;按产业结构和经济发展水平分类结果均在低产业结构水平和低经济发展水平下,数字经济对经济发展有更强的促进作用,并随着第三产业占比和经济发展水平的提高而减弱。
This paper focuses on the impact of the digital economy on urban economic development and its heterogeneity analysis.Based on the digital economy development level of 270 prefecture-level cities in China from 2011 to 2020,an empirical model was constructed to test the impact of digital economy development on economic development.The results show that the digital economy has significantly promoted economic development,and thisfinding remains robust after stability testing.In terms of heterogeneity analysis,the digital economy’s promotion effect in Central China is more significant than China’s eastern and western regions.According to the classification results based on industrial structure and economic development levels,the digital economy has a stronger role in promoting economic development in areas with low industrial structure and low economic development levels.However,this promotion effect weakens as the proportion of the tertiary industry and the level of economic development increase.
