Abstract:

The paper employs the rural industrial integration development pilot policy as a quasi-natural experiment, based on unbalanced panel data from 1291 counties in China from 1999 to 2022, and uses the Difference-in-Differences (DiD) method to study how rural industrial integration development affects the urban-rural income gap. Research has found that the integrated development of rural industries can significantly narrow the income gap between urban and rural areas in counties, and the optimization of industrial structure, new urbanization, and the synergistic effect of the two are the main mechanisms involved. The effect of narrowing the urban-rural income gap through the integration of rural industries is more pronounced in western regions and areas with larger urban-rural income gaps. The integrated development of rural industries has brought about an increase in the income levels of both urban and rural residents, and the growth rate of rural residents' income is greater than that of urban residents, which is in line with China's development goal of common prosperity. Based on this, in the future, the pilot scope of rural industrial integration should be further expanded, the policy support system should be improved, the coordinated development of urban and rural areas should be coordinated, the optimization of industrial structure should be promoted, and the linkage between rural industrial structure optimization and new urbanization should be promoted.

Key words: integration of rural industries, income gap between urban and rural area, the Difference-in-Differences (DiD) method, coupling coordination degree

摘要：

文章将农村产业融合发展试点政策作为一项准自然实验，基于1999—2022年我国1291个县域的非平衡面板数据，采用双重差分模型研究农村产业融合发展如何影响城乡收入差距。研究发现：农村产业融合发展能够显著缩小县域城乡收入差距，且产业结构优化、新型城镇化以及二者的协同效应是主要的作用机制；农村产业融合发展缩小城乡收入差距的效果在西部地区、城乡收入差距较大地区更为明显；农村产业融合发展同时带来城镇居民与农村居民收入水平的提升，且农村居民收入的增长幅度大于城镇居民，契合共同富裕的发展目标。今后应进一步扩大农村产业融合试点范围，完善政策扶持体系，统筹城乡协调发展，推动产业结构优化，促进农村产业结构优化与新型城镇化联动发展。
