共同富裕背景下生产性服务业对城乡收入差距的影响——基于生产要素的空间计量和门槛效应分析

Producer Services and Urban-Rural Income Gap in the Context of Common Prosperity:Spatial Econometric and Threshold Effect Analysis Based on Production Factors

文章基于2005—2019年省域面板数据,采用空间计量、门槛效应检验生产性服务业影响城乡收入的要素和区域差异。研究表明:生产性服务业劳动和资本投入对城乡收入差距的影响均呈现“U”型,且存在显著的空间溢出效应;门槛效应检验表明,随着市场化程度的增强,生产性服务业劳动投入对城乡居民收入差距存在显著的二重门槛效应,但资本投入不存在显著门槛效应;机制及异质性检验中,随着私营经济活跃度的增加,南方地区生产性服务业劳动和资本投入对城乡收入差距均呈现负向影响,但北方地区资本对城乡收入差距呈现负向影响,劳动对城乡收入差距呈正向影响并逐步降低。研究结果有助于优化生产性服务业要素投入数量和结构,为共同富裕的实现提供一定参考。

Based on provincial panel data from 2005 to 2019,this paper uses spatial econometric and threshold effect to test the factors and regional differences of producer services affecting urban-rural income.The research shows that the impact of labor and capital investment in producer services on urban-rural income gap is "U" shaped,and there is a significant spatial spillover effect;the threshold effect test shows that with the enhancement of the degree of marketization,there is a significant double threshold effect of labor investment in producer services on the income gap between urban and rural residents,but there is no significant threshold effect of capital investment;in the mechanism and heterogeneity test,with the increase of private economic activity,labor and capital investment in producer services in the south has a negative impact on the urbanrural income gap,while capital in the north has a negative impact on the urban-rural income gap,and labor has a positive impact on the urban-rural income gap and gradually reduces it.The research results help to optimize the quantity and structure of factor inputs in producer services,and provide some reference for the realization of common prosperity.
