革命老区振兴规划实施的共同富裕效应——基于城乡收入差距视角

The Common Prosperity Effect of the Implementation of the National Revitalization Plan for Old Revolutionary Areas: From the Perspective of Urban-rural Income Gap

本文以城乡收入差距为切入点,基于2009-2019年1950个县域的面板数据,采用多期双重差分模型研究革命老区振兴规划实施对城乡收入差距的影响及其作用机理,为推动农民农村共同富裕提供科学依据。研究发现:革命老区振兴规划的实施能缩小县域城乡收入差距、增加农村居民收入,且主要通过加强基础设施建设、增加地方财政投入、提高城镇化水平和促进农业发展等途径缩小城乡收入差距。革命老区振兴规划的实施对经济发展水平较低县域、中西部县域和数字普惠金融发展水平较高县域城乡收入差距的缩小效果更突出,且只有当县域城乡收入差距较大时革命老区振兴规划实施对城乡收入差距的缩小作用才有效。此外,革命老区振兴规划实施还具有空间溢出效应,能缩小毗邻县域的城乡收入差距。

Focused on the urban-rural income gap, this paper utilizes a panel dataset of 1950 counties from 2009 to 2019 and adopts the multi-period Difference-in-differences(DID) method to analyze the impact and mechanism of implementation of the National Revitalization Plan for Old Revolutionary Areas on the urban-rural income gap, providing policy implications for promoting common prosperity of farmers in rural areas. We find that the implementation of the National Revitalization Plan for Old Revolutionary Areas narrows the income gap between urban and rural areas within a county and raises the income level of rural residents, mainly by strengthening infrastructure construction, increasing local financial investment, accelerating urbanization, and promoting agricultural development. The implementation of the National Revitalization Plan for Old Revolutionary Areas has a stronger effect on narrowing the urban-rural income gap in counties in the central and western regions, counties with low levels of economic development, and counties with high levels of digital financial inclusion, and the implementation of the National Revitalization Plan for Old Revolutionary Areas reduces urban and rural income gaps only when the within-county gaps are wide. In addition, the implementation of the National Revitalization Plan for Old Revolutionary Areas also has a spatial spillover effect narrowing the urban-rural income gap in adjacent counties.
