居民消费对区域经济增长的空间变异性研究——基于地理加权回归模型的实证分析

Study on the Spatial Variability of the Regional Economic Growth of the Residents——Empirical analysis based on geographical weighted regression model

采用空间计量经济学的方法,通过对2013年中国31个省、市、自治区居民消费和国内生产总值这两个重要的经济指标进行分析,探讨居民消费对经济增长的影响.引入地理加权回归,从区域差异的角度出发,分析不同省域中居民消费对经济增长的不同影响.研究结果表明:各省域经济增长存在显著的空间相关性,且居民消费对经济增长存在正向影响,这种影响随着空间位置的变化而改变,即各省域之间有显著性差别,存在空间异质性.

We use the method of Spatial Econometrics. By 2013 consumption and gross domestic product of 31 provinces （autonomous regions and municipalities） residents of these two important economic indicators were analyzed to explore the impact of consumption on economic growth. Using geographically weighted regression method, from the perspective of regional differences, analyzes the residents＂ consumption in different provinces domain different effects on economic growth. The research results show that the residents＂ consumption has positive effect on economic growth, but the effect is changes in the space position changes, is not a fixed constant, namely there exists a spatial heterogeneity.
