鄱阳湖生态经济区粮食全要素生产率研究——基于25个县(市)面板数据的DEA分析

A Study on Total Factor Productivity of Grain in Poyang Lake Eco-economic Zone:The Panel Data of 25 Counties(Cities) Bsed on DEA analysis.

鄱阳湖生态经济区作为江西省传统农区,其粮食生产在江西省粮食生产格局中占有重要地位。本文采用DEA分析的Malmquist指数模型,实证分析了鄱阳湖生态经济区25个县(市)粮食全要素生产率(TFP)变化状况。整体来看,2000-2010年鄱阳湖生态经济区粮食全要素生产率整体呈上升趋势,其中技术进步是导致全要素生产率上升的主要因素。通过进一步分析得出,全要素生产率的增长主要来自于技术进步。就各县(市)来看,永修县、瑞昌市、余江县和贵溪市4个县(市)粮食全要素生产率下降,其他21个县(市)粮食全要素生产率均上升。在此基础上,本文就如何提高粮食全要素生产率提出了相应的政策建议。

Poyang Lake Ecological Economic Zone （PLEEZ）as a traditional agricultural area in Jiangxi province, the grain production plays an important role in the pattern of grain production in Jiangxi province. This paper uses Malmquist index model based on DEA analysis, the empirical analysis of 25 counties（cities） in PLEEZ grain Total Factor Productivity （TFP） growth. The results show that. from 2000 to 2010, PLEEZ grain TFP is ris- ing. Further analysis of its decomposition, the growth of TFP depends largely on technological progress. Yongxiu country, Ruichang city, Yujiang county and Guixi city etc., 4 counties （cities） grain TFP are declining, other 21 counties （cities） grain TFP are rising. On this basis, corresponding policy recommendations are put forward.
