城市群多中心城镇体系与农村减贫

Polycentric Urban System in Urban Agglomerations and Rural Poverty Alleviation

从多中心化这一城市群空间发展模式入手,探讨其对农村减贫的影响机制和效应强度。实证结果表明,只有在经济发展水平较高的东部地区,城市群多中心程度的增加才表现出显著的农村贫困消减效应。机制分析表明,“网络货币外部性”的存在是城市群多中心体系促进农村贫困缓解的重要因素。调节作用发现,东部区域的城市群一体化水平增加有利于其多中心体系的减贫效果,但中西部城市群一体化水平的提高并未表现出显著的调节效应。

Starting with the spatial development model of multi-center urban agglomeration,this article attempts to discuss the mechanism and intensity of its impact on rural poverty reduction.The empirical results show that only in the eastern region with high economic development,multi-centralization of urban agglomeration has significant reduction effect on rural poverty.Mechanism analysis shows that multi-center system of urban agglomeration alleviates rural poverty mainly through“network currency externality”.The moderating effect shows that the increase of the integration level of urban agglomerations in the eastern region is beneficial to the poverty reduction effect of the polycentric system,but the improvement of the integration level of urban agglomerations in the central and western regions does not show a significant moderating effect.
