数字经济嵌入农业发展是否助推了长江经济带城乡均衡收入？
Whether the Digital Economy Embedded in Agricultural Development Has Boosted the Urban-Rural Balance Income in the Yangtze River Economic Belt

本文基于2011~2021年长江经济带11个省级面板数据，构建数字经济嵌入农业发展评价体系，运用主成分分析法和面板回归模型分析数字经济嵌入农业发展对长江经济带城乡均衡收入的影响。研究结果表明：(1) 研究期间数字经济嵌入农业发展水平呈稳步上升趋势，数字经济嵌入农业发展可以显著促进长江经济带城乡收入均衡。(2) 投资、生产、流通、生活数字化对长江经济带城乡均衡收入的影响均具有显著正向效应，而经营数字化在研究期内的回归系数为负。(3) 数字经济嵌入农业发展对长江经济带城乡均衡收入的影响存在区域异质性，上游成渝经济区与中游城市群数字经济嵌入农业发展能够显著促进城乡均衡收入水平，而下游长三角地区的促进作用并不显著。基于此，政府应发挥数字经济对农村的辐射带动作用，不断弥合城乡“数字鸿沟”。
Based on the panel data of 11 provinces in the Yangtze River Economic Belt from 2011 to 2021, this paper constructs an evaluation system of digital economy embedded in agricultural development, and uses principal component analysis and panel regression model to analyze the impact of digital economy embedded in agricultural development on the balanced urban-rural income in the Yangtze River Economic Belt. The results show that: (1) During the study period, the digital economy embedded in agricultural development showed a steady upward trend, and the digital economy embedded in agricultural development could significantly promote the urban-rural income balance in the Yangtze River Economic Belt. (2) Digitalization of investment, production, circulation and life has a significant positive effect on the urban-rural equilibrium income in the Yangtze River Economic Belt, while the regression coefficient of digitalization of operation is negative during the study period. (3) There is regional heterogeneity in the impact of digital economy embedded in agricultural development on the urban-rural equilibrium income in the Yangtze River Economic Belt. The digital economy embedded in agricultural development in the upstream Chengdu-Chongqing economic zone and the midstream urban agglomeration can significantly promote the urban-rural equilibrium income level, while the promotion effect in the downstream Yangtze River Delta is not significant. Based on this, the government should give full play to the radiating role of the digital economy in rural areas and constantly bridge the “digital divide” between urban and rural areas.
