河西走廊农业生产效率评价——基于DEA模型和Malmquist指数分析

Evaluation of Agricultural Production Efficiency in Hexi Corridor—Based on DEA Model and Malmquist Index Analysis

本文基于河西走廊5个市2012—2021年的面板数据,运用DEA-BCC模型和Malmquist指数对农业生产效率进行分析。DEA-BCC模型静态分析结果显示:在研究期内,只有2015和2021年达到了DEA有效,实现了高效率生产,其余年份均为DEA无效;Malmquist指数动态分析结果显示:在研究期内,除2012—2013年外,其余年份农业全要素生产率均大于1,农业生产效率在逐步提升,生产率不高的主要原因在于生产规模较小,不能满足农业发展的需求。因此,本文提出河西走廊可以合理配置资源、合理使用化肥、扩大生产规模、提升科技水平,从而提高生产效率,提升农业经济发展水平。

This paper based on the panel data of five cities in Hexi Corridor from 2012 to 2021,uses DEABCC model and Malmquist index.The static analysis results of DEA-BCC model show that during the study period,only in 2015 and 2021 DEA was effective and the efficient production was realized,while other years were ineffective;the dynamic analysis results of Malmquistindex show that during the study period,except for 2012-2013,the agricultural total factor productivity is greater than 1,and the agricultural production efficiency was gradually improving.The main reason for the low productivity is that the production scale is small and cannot meet the needs of agricultural development.Therefore,this paper proposes that Hexi corridor can rationally allocate resources,rationally use chemical fertilizer,expand the production scale and improve the level of science and technology,so as to improve the production efficiency and enhance the level of agricultural economic development.
