摘要

本文擬針對台灣地區農業合作社場之經營效率進行評估，採用三階段DEA模型來摒除外在環境變數對於農業合作社場之影響，試圖修正資料包絡分析法無法處理隨機干擾因素的缺點，以衡量各個農業合作社場在相同的環境下之經營成效，並作為客觀的經營效率之評量。
實證結果顯示，第三階段之效率估計值較第一階段低，顯示未調整環境變數前，農業合作社場之效率值有嚴重被高估之現象。又台灣地區農業合作社場總技術效率值平均為0.75，表仍有25%之經營改善空間；但若未考慮環境變數之影響，農業合作社場總技術效率估計值會高估6.9%。

This study aimed to assess the operational efficiency of the agriculture cooperatives in Taiwan by the Three Stage DEA Model. Use of the Three Stage DEA Model can rule out the influence of environmental variables on agriculture cooperatives and also overcome data envelopment analysis deficiencies like random noise to assess agriculture cooperative performance under the same environment.
The results of the study show that the estimated value of third stage efficiency is lower than that of the first stage, indicating agriculture cooperative efficiency has been highly overestimated before environmental variables are adjusted. In addition, Taiwan agriculture cooperatives obtain an average value of 0.75 in technical efficiency, suggesting that the operation of agricultural cooperatives can be improved by 25% more. Finally, technical efficiency could be overestimated by 6.9% if the environmental variable was not taken into account in this study.
