全国视域下的粮食主产区农业全要素生产率实证分析——基于1998-2012年省际面板数据

Nationwide Perspective on Agriculture TFP in Major Grain-producing Area in China Based on the Panel Data of Provinces from 1998 to 2012 and DEA-Malmquist Index Approach

基于1998-2012年省际面板数据,运用DEA-Malmquist指数法,测算全国、粮食主产区和各省份农业全要素生产率,进而分析粮食主产区农业全要素生产率的时空差异。研究表明,粮食主产区农业全要素生产率增长速度略快于全国平均水平;全国和粮食主产区农业全要素生产率增长,都源于技术进步的推动,而技术效率则起制约作用;粮食主产区内各子区域之间和省份之间农业全要素生产率增长速度和增长源泉均存在较大差异。

Based on the panel data of provinces from 1998 to 2012, the agriculture total factor productivity （ATFP） in China, in Major Grain-producing Area （MGA） and in all provinces in China were measured with DEA-Malmquist index method. The spatiotemporal differences of ATFP in MGA were analyzed. The results showed that the growth rate of ATFP in MGA was faster than the average level in China. The progress of technical played an impotant role in the growth of ATFP. There were difference in the rate and momentums of ATFP growth in different provinces or different subregions of MGA.
