【摘要】 经济增长存在收敛性符合人们的直观感觉，也是经济增长理论的重要结论之一，但是中国城市经济增长似乎并不符合收敛性特征。城市人均GDP对数与经济增速更有可能是正线性关系，中国城市经济增长实践或许与直观感觉、经济理论存在矛盾。本文深入讨论中国城市经济增长与人口增速、科技进步的线性关系，发现中国城市经济增速与人口增速、科技进步之和呈现比较明显的正线性相关关系。这说明中国城市经济增长与经济理论是相符的，也就是中国城市经济增长存在收敛性，只是由于生产要素的变化导致经济增速出现了较大差异，进而影响了人们的直观感觉。更多还原

【Abstract】 The convergence of economic growth is in line with people intuitive feelings and is also one of the important conclusions of economic growth theory. However,the economic growth of the China cities does not seem to conform to the characteristics of convergence. China cities GDP per capita and economic growth rate are more likely to have a positive linear relationship. The economic growth of China cities may contradict intuitive feelings and economic theories. In depth discussion of the linear relationship between population growth rate,science progress and China cities economic growth. This paper finds that there is a relatively positive linear correlation between the sum of population growth rate and science progress and China cities economic growth. This shows that China cities economic growth is consistent with economic theory,that is,there is convergence in the economic growth of China cities. It is just that there are big differences in economic growth due to changes in production factors,which in turn affects people intuitive feelings.更多还原
