中国区域经济增长条件收敛分析——基于扩展Solow模型的实证研究

Analysis of Conditional Convergence of China's Regional Economic growth——Empirical Analysis Based on Extensive Solow Model

以Solow模型(1956)为基础,把人力资本和制度因素同时纳入新古典经济增长模型中,构造了一个包含人力资本和制度因素的扩展Solow模型。运用面板数据(Panel data)系统广义矩估计(SYS-GMM)方法,对1978年改革开放以来各省的经济增长差异进行了实证分析。研究结果发现,中国各地区间的经济增长存在显著的条件收敛(conditional convergence)特征,即在控制了各省间人口增长率、物质资本投资率、人力资本水平和制度因素差异后,可以观测到明显的经济增长收敛趋势。

Based on Solow（1956） nmdel, the paper introduces human capital and institution into new-classical economic growth model and constructs an extensive Solow model with human capital and institution. The paper draws on SYS - GMM estimation of panel＇data to carry out an empirical analysis of inter-provincial growth variance across provinces in China since 1978. The results show thai the conditional convergence has been identified, that is, given the same level of physical capital investment rate, human capital, market openness and outward opening-up the economic provinces have demonstrated a certain growth convergence. The empirical results show that the extensive MRW model with human capital and institution can explain the phenomenon of inequality in china＇s districts and its estimation is robust.
