中国农业生产率增长的地区差距与收敛性分析

在利用非参数的DEA曼奎斯特生产率指数方法对中国农业全要素生产率进行求解的基础上，论文运用经济增长收敛理论对农业TFP（Total Factor Productivity）增长在1978～2005年转型期的收敛性情况进行检验，这包括从σ收敛、绝对β收敛到条件β收敛的全面检验。论文基本结论表明，整个转型期中国农业TFP增长并不存在显著的σ收敛和绝对β收敛性，但存在显著的条件β收敛性。论文最终还认为，通过一定政策性措施来实现中国农业TFP增长的绝对收敛是可能的。

Empirical Analysis on the Regional Disparity and the Convergence Hypothesis of China's Agricultural Productivity Growth

Based on the measurement and calculation of Chinese agricultural Total Factor Productivity using the non-parameter Data Envelopment Analysis and Malmquist productivity index approach,the paper has tested the convergence hypothesis of the agricultural TFP growth in China for the transformational period(1978~2005),and this includes the σ convergence,unconditional β convergence and the conditional β convergence.The main conclusion is that no remarkable σ convergence and unconditional β convergence exist in the TFP growth,but the remarkable conditional β convergence exists in the TFP growth.In the end,the paper points out that it's impossible to realize the unconditional β convergence of the agricultural TFP growth by some effective policy.
