摘　　要：数字经济正在成长为中国宏观经济发展的重要支撑。基于2012-2022年长江经济带11个省市的面板数据,分析数字经济对区域经济发展差距的影响及作用机制,是具有借鉴意义的实证研究。研究结果显示,数字经济有利于缩小区域经济发展差距,在稳健性检验、内生性检验下结论成立。异质性检验表明,数字经济发展能够缩小长江经济带上游、下游省市经济发展差距,但是对中游地区影响不显著。影响机制检验表明,对于长江经济带而言,数字经济主要通过加强经济联系、提升技术创新水平两个途径缩小区域经济发展差距。The digital economy is emerging as a significant pillar for China’s macroeconomic development.Based on panel data from 11 provinces and cities along the Yangtze River Economic Belt from 2012 to 2022,the researchers empirically investigate the impact and mechanism of the digital economy on regional economic development disparities,providing a reference for similar studies.The results indicate that the digital economy helps reduce regional economic disparities,a conclusion that holds true after robustness and endogeneity tests.Heterogeneity analysis shows that the digital economy can narrow the economic gaps between upstream and downstream provinces and cities in the Yangtze River Economic Belt,but its impact on the midstream region is not significant.The mechanism test reveals that,for the Yangtze River Economic Belt,the digital economy primarily reduces regional economic disparities by enhancing economic connectivity and improving technological innovation levels.
