本文在传统MRW模型的基础之上引入了经济开放程度、市场化程度以及基础设施建设水平等三个控制变量, 构建了扩展MRW模型.借助MATLAB软件对中国1992年—2016年区域经济增长的收敛性进行测算分析.研究结果表明:中国各省区人均GDP的空间分布存在正向空间自相关以及显著的空间异质性.从长期看中国区域经济增长存在条件收敛, 收敛速度为3. 46％, 已有的研究确实存在经济增长速度被高估的现象.劳动人口增长率、经济开放度、人力资本储蓄率以及物质资本储蓄率等都与中国人均GDP增长存在显著的空间正相关关系;与此同时, 政府消费占GDP比重过高、基础设施重复建设都对经济增长具有明显的负向作用.因此在制定相关政策时, 应当考虑区域之间的空间溢出效应, 在促%On the basis of the traditional MRW model, this paper introduces three control variables, such as the degree of economic openness, the degree of marketization and the level of infrastructure construction, and constructs the extended MRW model. With the help of MATLAB software, the convergence of China's regional economic growth in the past 1992-2016 years is calculated and analyzed. The results show that there exists positive spatial autocorrelation and significant spatial heterogeneity in the spatial distribution of per capita GDP in China's provinces. In the long run, China's regional economic growth is conditional convergence with a convergence rate of 3. 46％. There is a significant spatial positive correlation between the growth rate of labor population, economic openness, the rate of human capital savings and the rate of material capital savings, such as the growth of China's per capita GDP. At the same time, government consumption accounts for a high proportion of GDP and infrastructure construction has a negative effect on economic growth.
