中文摘要：

运用生产函数法估计出我国分城乡全要素生产率指数,结论表明,在1980~2007年期间农村全要素生产率指数年均增长2.57%,而城镇全要素生产率指数年均增长4.13%。在此基础上,进一步分析得到全要素生产率对农村居民人均纯收入增长的贡献率为60.51%,对城镇居民人均可支配收入增长的贡献率为40.43%,城乡全要素生产率差距拉大1%,城乡居民人均收入差距将拉大6.8741%,表明除全要素生产率因素外还有诸如政策、人力资本等其他因素的综合影响抑制了收入差距的逐步拉大。

英文摘要：

The paper estimates TFP indexes of urban and rural by production function.The results show that TFP increase 2.57% per year between 1980 and 2007 in rural,4.13% per year in urban.Based on the indexes,the empirical results show that the contribution of TFP to per capita annual net income of rural households is 60.51% and to that of urban households is 40.43%.The two TFP indexes＇ gap widen 1%,the income gap widen 6.8741%.There are some factors besides TFP restraint the income gap widening,such as policy and human capital etc.
