我国粳稻生产效率变动及收敛性分析

采用DEA-Malmquist指数法,对2001-2012年我国粳稻主要产区12个省份的粳稻生产投入产出面板数据进行实证分析,并测算了我国粳稻主产区全要素投入产出效率,对粳稻全要素生产率变动及其收敛性进行分析.结果表明:2001-2012年中国粳稻TFP的平均增长率为-2.3％,技术进步为-2.2％,技术进步的下滑是决定全要素增长率下降的主要因素.各粳稻生产省份的TFP存在显著差异,其中,黑龙江省和浙江省的粳稻生产效率水平高于其他省份.通过省际间的收敛性来看,粳稻主产区全要素生产率具有σ收敛性.

Production efficiency change and convergence analysis of japonica rice in China LIU De-juan

The total factor input-output efficiencies of japonica rice production in our country were deduced by analyzing the output-input panel data (2001-2012) of 12 provinces of japonica rice main production areas. The results showed that, from 2001 to 2012, the average rate of growth of the total factor productivity (TFP) was -2.3% and the technological progress was -2.2%. The decline of technical progress was the main cause of the decrease of TFP. Moreover, distinctions existed among the TFPs of these provinces, while the TFPs of Heilongjiang and Jiangsu Provinces were higher than that of other provinces. Further convergence test indicated that the TFP of main production areas had convergence trend.
