摘要

本文以2012年中國海南省68家芒果農場為研究對象,將芒果農場以地理位置分為西部,南部二個群組；以農場主屬性分為臺商,海南本地農民，福建人三個群組；及土地屬性分為自有農地，承包農地,承包農場三個群組來進行效率分析。首先,應用共同邊界資料包絡法（Metafrontier DEA），推估群組技術效率,共同技術效率及共同技術率;其次,再以 super-efficiency 及 Tobit 迴歸模型探討影響技術效率及差異之因素.實證結果顯示：以地理位置對芒果生產效率無顯著差異,表示海南省西部及南部皆適合芒果生產.進一步分析，發現福建人的共同效率值(1.015)高於臺商(0.849)，海南本地農民(0.694)，自有農地共同效率值(0.941)高於承包農場(0.27)，承包農地(0.778).表示福建人及自有農地的技術效率最佳，其運用的生產技術最接近群組的共同生產技術水準.最後，生產經驗增加及提早產期等因素，將有助於生產效率得提升。

This dissertation uses the concept of Metafrontier Data Envelopment Analysis (DEA), the super-efficiency and the Tobit regression model to compare the technical efficiency (TE), scale efficiency (SE) and what factors inference the mango production in Hainan at 2012 for 68 DMU. Empirical result showed that for the regional the farm place analysis, The average TE and SE in South (0.566, 0.725) and West (0.577, 0.792) are very close. It proof the South and West was same in efficiency of mango production. Moreover, the Birth Place for the farmer have different TE and SE, but in the Tobit regression model, For the special management method case easy to sale and have high price, could increase the efficiency in the west of Hainan. For the farmers birthplace, the Fujian performed the highest score (1.015), followed by the Taiwanese (0.849) and the Hainan (0.694) that was show the Fujian could produce mango with high efficiency in technology production in the average. For the land ownership analysis, the own land performed the highest score (0.941), followed by the renting farm (0.827) and the renting land (0.778). The Tobit regression model show that experience and early harvesting practical could increase the super-efficiency scores of mango production in the Hainan.
