金融集聚、生产率增长与城乡收入差距的实证分析——基于动态空间面板模型

本文利用中国2003-2013年285个地级及以上城市的统计数据，采用动态空间面板模型实证分析了金融集聚对城市总体生产率增长及其内部城乡收入差距的影响，研究结论表明：金融集聚是促进城市总体生产率增长的重要推动力，同时也是导致城市内部城乡收入差距扩大的关键因素，这主要是因为金融集聚显著推动了城市居民人均收入水平的提高，而对农村居民人均收入水平的提升作用不显著。本文的政策含义在于，在城市金融集聚的扩散阶段还没有到来之前，政府旨在缓解城乡收入差距的金融政策可能会抑制城市总体生产率增长。

The Empirical Analyses between Financial Agglomeration,Productivity Growth and Urban-rural Income Gap-Base on Dynamic Spatial Panel Model

Analyzing the effects of financial agglomeration on productivity growth and urban-rural income cap can provide corresponding policy recommendations for the unification of efficiency and equality from the perspective of financial development. Based on the data of China's 285 cities in 2003-2014, the effects of financial agglomeration on urban overall productivity growth and urban-rural income gap are analyzed using a dynamic spatial panel model. The results show that although financial agglomeration is an important force to promote urban overall productivity growth, it is also a key factor that leads to the widening of urban-rural income gap. This is mainly because that financial agglomeration can significantly increase the per capita income level of urban residents, but the effect of financial agglomeration on the increase of the per capita income level of rural residents is not significant. The policy implication of this paper is that before the arrival of the spread stage of financial agglomeration, financial policies that aim to alleviate the urban-rural income gap may inhabit urban overall productivity growth.
