中国地区收入差距、全要素生产率及其收敛分析

本文在测算和分析1982—2002年省区全要素生产率(TFP)的基础上进行TFP的收敛检验,并与收入(劳均GDP)的收敛模式做了对比分析。分析表明TFP解释了我国省区收入差距的主要部分;我们应用OLS、PanelData固定效应估计方法和DynamicPanelData(一阶差分GMM)方法进行收敛检验,得出的结论是:TFP与收入的收敛模式具有很大的相似性,全国范围内没有绝对收敛,只有条件收敛,但是TFP的收敛速度明显高于收入的收敛速度。三大地区中只有东部地区存在俱乐部收敛现象。而且,我国TFP与收入的收敛模式与世界范围的TFP和收入的收敛模式具有很大的相似性。

The Disparity of Income, TFP and the Convergence Hypothesis in Chinese Provinces

We study the convergence of total factor productivity(TFP)in Chinese provinces during 1982—2002 and compare it with the mode of income(GDP per labor)convergence. On the accounting basis our analysis shows that the differences in TFP can explain the bulk of income disparity. OLS, Panel Data fixed-effect and Dynamic Panel Data first-differenced GMM estimated methods support both conditional convergence of TFP and income while the speed of TFP is much faster than that of income. Only the east region has club-convergence. Further more, the Chinese provincial convergence modes of TFP and income are very similar to those of cross-country.
