基于空间计量模型的陕西省县域经济趋同性研究

Study on Economic Convergence of Counties in Shaanxi Province Based on Spatial Econometric Model

本文采用面板数据空间计量模型测度了陕西省83个县(市)2003—2011年经济增长的趋同状况。经济计量结果表明:考虑空间效应之前,陕西省县域经济增长既不存在绝对β趋同,也不存在条件β趋同;加入空间效应之后,存在着显著的条件趋同趋势,说明地区间的空间效应缩小了陕西省县域经济的差异,从而促进了县域经济的趋同。其中,工业化水平、物质资本、人力资本和政府支出对经济趋同有正向影响,而居民储蓄对经济趋同有负向影响。

Economic growth convergence of 83 counties （municipalities） in Shaanxi province from 2003 to 2011 is measured by using panel data spatial econometric model. The conclusions from econometric analysis are as follows： neither absolute 13 economic convergence nor conditional 13 economic convergence exists for counties in Shaanxi province without considering spatial effect, but significant conditional convergence exists after introducing spatial effect, which shows that spatial effect helps bridge the economic gap among counties in Shaanxi province and promote the economic convergence of counties. In addition, the level of industrialization, physical capital, human capital, and government spending have positive effects on economic convergence, while household savings has negative effects on economic convergence.
