高质量发展背景下中国经济差距的时空演化及其影响机理分析

An Analysis of Spatial-Temporal Evolution of China’s Economic Gap and Its Influencing Mechanism

为了探讨高质量发展背景下中国经济差距的时空演化特征及其影响机理,本文测算了新中国成立70年以来中国各省域的经济密度,并进一步计算其变差系数、相对发展率及莫兰指数,对东中西部三大区域进行对比分析;同时运用空间计量模型分析企业密度对经济密度的影响机理。研究发现,东中西部三大区域的经济密度呈现出不断上升的趋势,区域之间差异明显,且区域内不同省域的经济发展水平不一,经济发展速度存在较大差异;各省域的经济密度在整个空间上存在正相关性,且这种相关性逐渐增加,空间差异正在不断减小;企业密度对经济密度具有显著的正向影响,从业人数、交通区位、科技发展水平、城市化水平以及产业结构等与经济密度之间具有显著的正相关关系。

In order to explore the spatial and temporal evolution characteristics of China’s economic disparity and its influencing mechanism under the background of high-quality development,this paper calculates the economic density of China’s provinces since the founding of New China 70 years ago,and further calculates its variation coefficient,relative development rate and Moran’s I index to make a comparative analysis of the three major regions in the eastern,central and western regions.Spatial econometric model is used to analyze the influence mechanism of firm density on economic density.The study finds that the economic density of the three major regions in the east,central and western regions shows a rising trend,with obvious regional differences,and the economic development level of different provinces in the region varies greatly,and the economic development speed of different provinces varies greatly;the economic density of each province has a positive correlation in the whole space,and this correlation increases gradually.In addition,the spatial difference is decreasing;the density of enterprises has a significant positive impact on economic density,and there is a significant positive correlation between the number of employees,traffic location,the level of scientific and technological development,urbanization level and industrial structure and economic density.
