基于SDEA和Malmqusit指数的河南农业生产效率分析

Analysis of Agricultural Production Efficiency in Henan Province Based on SDEA and Malmqusit Index

利用SDEA和Malmqusit指数综合分析河南省农业生产效率的时空变化特征。通过定量分析,结果表明:自2003年随着我国一系列惠农政策的实施,河南省农业生产效率增长趋势显著,且近年来其农业生产效率的变化幅度高于全国平均水平;整体而言,河南各市农业生产综合效率的提高多源于其农业生产资源投入要素技术变化率的拉动,但各市农业生产的纯技术效率和规模效率差异程度较大,农业生产管理技术水平显著带动农业产出提高的地区主要为中原经济建设核心区及传统农业区,部分地区农业投入出现冗余现象。

This paper analyzes the spatio-temporal variation characteristics of agricultural production efficiency in Henan Province based on SDEA and Matmqusit index. The results of the quantitative calculation show that the agriculture production efficiency has had a substantial increase since 2003 as China continues to carry out a series of benefiting-peasants policies and that change range of Henan Province is higher than the national average level in recent years. The improvement of agriculture synthetic efficiency has chiefly resultd from the growth of the technical change rates of agricultural production; however, there have been differences among the cities in pure technical efficiencies and scale efficiencies. The cities in Central Plain economic construction core zone and traditional agricultural zone have significantly improved their agricultural output by means of agricultural production and technologic management, with the phenomenon of redundant agricultural investment in some areas.
