基于数据包络分析法的湖南省“两型”农业生产效率评价

Evaluation of Resource-saving and Environment-friendly Oriented Agricultural Productivity in Hunan Province Based on Data Envelopment Analysis(DEA)

在建立两型农业发展状况评价指标体系的基础上,运用DEA方法对湖南省14个市州2008年农业生产的效率进行评价。通过对湖南省各市州农业生产的投入与产出数据运算结果的分析,得出长沙、株洲、湘潭和常德4个地区的农业生产效率相对有效,农业产出已达到最优水平,衡阳等10地区农业生产效率较低,处于规模效益递减状态。对各市州的投入与产出的投影分析表明,衡阳等地区存在一些农业生产要素投入过剩或者要素的利用效率需要提高等情况。

This paper employs DEA theory to evaluate agricultural production efficiency of 14 cities in Hunan Province in 2008 based on an index system of evaluation of regional agriculture development status on resource-conserving and environment-friendly.Via empirical study on input-output data of agricultural production,this paper concludes that Changsha,Zhuzhou,Xiangtan and Changde cities have reached the optimal scale of agricultural production and their investment structure is effective as well;due to investment in agricultural production structure is not reasonable,Hengyang and nine other cities are still relatively low in agricultural productivity.Overall,resource-saving and environment-friendly oriented society agriculture degree of agricultural production in Hunan Province is not very high,scale efficiency and technical efficiency need to be improved,to further increase investment in agricultural technology and modernization.
