【摘要】 运用基于DEA的Malmquist指数分析方法和省级油菜成本收益数据,对中国各地区油菜生产率的增长状况进行了实证分析,并将生产率进一步分解为技术进步和技术效率,在此基础上对全要素生产率地区间差距进行了绝对收敛和条件收敛检验。结果显示:1979-2005年中国油菜生产率平均增长率为-6%,技术进步为-5.8%,技术效率为-0.2%,生产率的下降主要是由技术退步所引起的;全国各油菜主产省的生产率不仅存在σ收敛,并且存在绝对β收敛和条件β收敛,其收敛速度分别为7.59%和8.93%,而收敛现象主要发生在20世纪80年代。更多还原

【Abstract】 In this paper,we use the Malmquist index based on DEA and provincial cost-benefit data to analyze rape productivity growth conditions in various regions of China and further divide productivity into technological progress and technical efficiency.On this basis we test the absolute convergence and the conditional convergence of total factor productivity in the gaps between the regions.The conclusions show that the average growth rate of rape productivity of China is -6%,-5.8% for technological progress and -0.2% for technical efficiency.The decline in productivity is primarily caused by technical setbacks.There is not only the productivity of σ convergence,but also absolutely β convergence and conditions β convergence.The convergence rate were 7.59% and 8.93%,and the convergence phenomenon occurred mainly in the 1980s.更多还原
