海南省农业生产效率的DEA分析

在总结国内一些运用DEA研究农业生产效率的文献的基础上,运用DEA模型对海南省18个县市2002、2005、2008年的农业生产效率进行实证分析。结果表明,2005年海南省由于遭受罕见的旱灾和风灾,其各市县的农业生产的有效性值均相对较低;2002、2005和2008年农业生产均属于DEA有效的地区是琼海市、屯昌县、临高县、儋州市、琼中县和白沙县;2002年的海口市、五指山市、保亭县,2005年的陵水县和2008年的三亚市、东方市也属于DEA有效地区,表明这些地区在相应年份其投入产出处于最佳状态。最后对2008年海南省6个非DEA有效市县进行投影分析,据此指出了改善这些地区农业生产效率的途径。

DEA Analvsis of Agricultural Production Efficiency in Hainan Province

On the basis of summarizing some literatures regarding research of agricultural production efficiency by using DEA at home,we conduct empirical analysis on agricultural production efficiency in 18 cities or counties of Hainan Province in the year 2002,2005 and 2008 by using DEA model.The results show that in 2005 Hainan Province suffered from unusual drought and windstorm,which made the effective value of agricultural production in all cities or counties extremely low;the regions with DEA effectiveness of agricultural production in the year 2002 and 2008 were Qionghai City,Tunchang County,Lingao County,Danzhou City,Qiongzhong County and Baisha County.Haikou City,Wuzhishan City and Baoting County in the year 2002,Lingshui county in the year 2005,and Sanya City and Dongfang City in the year 2008 were also regions with DEA effectiveness,indicating that the input-output of these regions in the corresponding years is in optimal state.Finally,we conduct projection analysis on six cities and counties with non-DEA effectiveness in the year 2008 in Hainan Province,and based on this,find out the approach of improving agricultural production efficiency in these regions.
