后发地区金融集聚、空间溢出与区域经济增长——基于广西14个城市空间面板杜宾模型研究

Financial Agglomeration,Spatial Spillovers and Regional Economic Growth in Post-Developed Areas——Based on the Space Durbin Model of 14 Cities in Guangxi

选取广西市域面板数据,利用SDM空间计量模型对广西金融集聚对经济增长的空间溢出效应进行了研究。运用SAR和SAC空间计量模型进行稳健性检验,结果表明,金融集聚、金融效率和政府行为对经济增长有显著的正向空间溢出效应,投资水平在区域经济增长中呈现负向空间溢出效应。此外,直接效应、间接效应和总效应的结果显示,金融集聚对本市经济增长的影响大于对相邻市经济增长的影响;本市金融效率对本市的经济增长有正向的促进作用,但对相邻城市的经济增长呈现负向的空间溢出效应。应加强城市之间的金融合作和政策协调,构建金融支点、金融增长极和金融中心三级联动的金融发展格局,发挥金融中心金融扩散的涓流效应。

Based on the panel data of cities in Guangxi from 2011 to 2016,this paper uses SDM to test the spatial spillover effect of financial agglomeration on economic growth in Guangxi. Besides,it carries out robustness tests through space measurement models SAR and SAC. The results show that there is a significant spatial self-correlation between economic growth and financial agglomeration. Financial agglomeration,financial efficiency and government behavior have significant positive spillover effects on economic growth,while investment levels show negative spatial spillover effects in regional economic growth. Besides,direct effect,indirect effect and total effect of the results show that the impact of financial agglomeration on the economic growth of the city is greater than that on the economic growth of the neighboring cities. The financial efficiency of the city has a positive effect on the economic growth of the city,but the economic growth of the neighboring cities shows a negative spatial spillover effect. Therefore,the government should strengthen the financial cooperation and policy coordination between cities,give play to the trickle-down effect of financial diffusion in financial centers,and enhance the financial development in Guangxi.
