以融合促振兴:县域城乡产业融合对共同富裕的影响研究

Promoting Revitalization Through Integration:Research on the Impact of County Urban-Rural Industrial Integration on Common Prosperity

以县域为载体推动城乡产业融合发展是实现中国式现代化的重要手段。基于2006-2021年我国1672个县域数据,构建城乡产业融合影响共同富裕的理论分析框架,并利用门槛模型和空间杜宾模型实证检验城乡产业融合对共同富裕的影响、作用渠道与空间溢出效应。研究表明:县域城乡产业融合对共同富裕的影响呈现“正U”型非线性特征,该结论经过一系列稳健性检验后依然成立。机制分析表明,县域城乡产业融合能够通过缓解融资约束和促进企业引培来推动共同富裕,但只有当县域城乡产业融合水平发展到一定程度时才成立。此外,县域城乡产业融合对共同富裕的影响效应在区域和城乡产业融合类型层面均表现出明显的异质性。进一步研究发现,县域城乡产业融合对共同富裕存在显著的正向空间溢出效应,而且县域要因地制宜地采取合适的城乡产业融合模式。据此,要加快推进县域城乡产业融合并优化县域金融扶持政策和加强企业引培力度,优化城乡产业空间布局,探索差异化城乡产业融合模式。

Promoting the urban-rural industrial integration at the county level is an important means to achieve Chinese-style modernization.Based on the data of 1672 counties in China from 2006 to 2021,we construct a theoretical analysis framework of the influence of urban-rural industrial integration on common prosperity and empirically test the influence of urban-rural industrial integration on common prosperity,its channels of action,and spatial spillover effects using the threshold model and spatial Durbin model.It is found that the impact of county urban-rural industrial integration on common prosper-ity has a positive U-shaped nonlinear characteristic,and this conclusion still holds after a series of robust-ness tests.Mechanism analyses show that the county urban-rural industrial integration can promote com-mon prosperity through alleviating financing constraints and fostering introduction of enterprises,but this is only effective when county urban-rural industrial integration develops to a certain degree.In addition,the impact of county urban-rural industrial integration on common prosperity shows significant heteroge-neity at both the regional and urban-rural industrial integration type levels.Further research finds a signifi-cant positive spatial spillover effect of county urban-rural industrial integration on common prosperity,and counties need to adopt appropriate urban-rural industrial integration models.Therefore,it is necessary to accelerate the county urban-rural industrial integration,optimize the financial support policies,strengthen the introduction and cultivation of enterprises,optimize the spatial distribution of urban and ru-ral industries,and explore differentiated modes of urban and rural industrial integration.
