不同空间网络关联情形下中国区域经济增长的收敛检验及协调发展

Convergence Test and Coordinated Development of China′s Regional Economic Growth under the Background of Different Spatial Network

本文基于1980-2015年中国省际面板数据,分别从经济发展、资本积累、商品贸易、金融发展四个维度,利用社会网络分析方法揭示中国区域经济增长空间关联网络结构,并以不同的空间关联网络作为权重,通过动态空间面板回归模型对经典β收敛进行检验。研究发现:传递性与交互性对于空间关联网络的形成存在显著作用,区域经济增长存在普遍的相关依赖关系,但网络关联性仍有较大提升空间;中国区域经济增长在不同的空间网络权重下均呈现收敛,但收敛速度不尽相同;区域经济增长在1991年前后表现出两种不同的收敛特征,1991年前区域经济分化趋势明显,1991年后区域经济β收敛特征显著;同时,区域经济增长存在一定程度的俱乐部收敛趋势。因此,在高质量发展阶段,必须高度重视空间关联网络对于区域经济增长的作用,以实现区域经济协调发展。

This paper used panel data of 28 provinces in China's Mainland from 1980 to 2015 to examine the structural characteristics of spatial correlation networks in China's regional economic growth from four aspects:economic development,capital accumulation,commodity trade and financial development,and to test the classical β convergence by dynamic spatial panel data regression model under the weights of different spatial networks. We found that transitiveness and interactivity have significant effects on the formation of spatial association networks,and that there is a general spatial dependence on regional economic growth,though there is still room for greater improvement in network association;global convergence exists under the weight of spatial network. However,under different spatial network weights,the speed of regional economic convergence is not the same;the convergence characteristics render differences before and after 1991. Before 1991,regional economic differentiation tended to be obvious. After 1991,the regional economic β convergence characteristics are significant. There is a certain degree of club convergence trend of regional economy growth. Therefore,in the stage of high quality development, we must attach great importance to the role of space-related networks in order to achieve coordinated regional economy development.
