基于DEA模型的农户林地经营效率分析——来自广东和江西的调研数据
|
摘要
基于广东和江西两省的调研数据,运用DEA方法对农户的林地经营效率进行测算,对不同品种的经营状况进行分析和讨论,得到:第一,江西省农户林地经营的效率平均值比广东的效率平均值要高,广东农户在种苗、化肥、农药的资本投入上存在较多冗余,江西农户只存在较少的劳动力投入冗余。第二,广东农户的杉木经营效率较高,桉树较低;江西农户的毛竹经营效率比杉木的经营效率要高。第三,桉树、松树、毛竹和杉木的经营呈现规模递增,而砂糖桔和肉桂则是呈现规模报酬递减。
Based on the survey data of household's management from Guangdong and Jiangxi province, the paper analyzes the sample households forestry management efficiency by using DEA model.We come to the following conclusions. Firstly, the average effi ciency of household forestry management in Jiangxi province is higher than that in Guangdong province. Secondly, for the samples of Guangdong province, the average management effi ciency of Chinese fi r is the highest, and the average management effi ciency of eucalyptus is relatively low. But for the samples of Jiangxi province, the average management effi ciency of moso bamboo is higher than Chinese fi r. Thirdly, eucalyptus, pine, moso bamboo and Chinese fi r are increasing in their returns of scale, while the sugar orange and cinnamon are decreasing in their returns of scale.
