区域价格水平差异是影响地区收入差距的重要因素。本文在度量我国31个省市空间价格指数和地区收入差距指数的基础上,分析了区域价格水平差异影响地区收入差距的机理,并建立空间面板数据模型实证分析了区域价格水平差异对我国地区收入差距的影响。研究结论认为,我国31个省市的空间价格指数在0.86-1.25较为合理的范围之间,收入差距指数在0.73-1.83较大的区间范围内,不同的省份之间存在着明显的价格水平差异和收入差距。我国区域价格水平差异每扩大1%,地区收入差距将扩大0.74%,经济发展水平的高低对地区收入差距的贡献度要大于区域价格水平差异。
Regional price level difference is an important factor affecting the regional income gap. Based on the measurement of the spatial price index and regional income gap index of 31 provinces and cities in our country, this paper analyzes the mechanism of regional price gap affecting regional income disparity and establishes a spatial panel data model to empirically analyze the impact of regional price level differences on China’s regional income The impact of the gap. The conclusion of the study is that the spatial price index of 31 provinces and cities in China is between 0.86 and 1.25, and the index of income gap is in the range of 0.73-1.83. There are obvious differences in price levels among different provinces And income gap. For every 1% increase in regional price level differences in our country, the regional income disparity will widen by 0.74%. The level of economic development contributes more to the regional income disparity than the regional price level.
