摘要

This article focuses on understanding how the Porcine Epidemic Diarrhea (PED) virus influenced the production efficiency of the swine industry in Taiwan. A total of 96 valid sample data were collected during March of 2014. The Data Envelopment Analysis (DEA) was adopted to evaluate production efficiency before, and after, the PED events. Results show that the PED events in Taiwan had weakened overall technical efficiency about 8.6%. Large scale farms, older farms, and farms in the Central area appeared to be the most heavily impacted. Lastly, the percentage change in production efficiency in the DEA estimation are very close to the percentage changes in inventory on farms reported by government. This supports our estimation of efficiency lost by the DEA practically.

本研究欲探討豬流行性下痢（PED）對台灣肉豬市場生產效率之影響，於2014年三月期間總共收集96筆有效養豬戶個體資料，本研究透過資料包絡分析法（DEA）估計在豬流行性下痢影響前與影響後之台灣肉豬產業生產效率變化。實證結果顯示豬流行性下痢影響台灣肉豬產業之生產效率降低達8.6％。規模較大、場齡較老以及位於中部的養豬戶受到較大的影響，同時本研究也發現政府部門當時所公布的豬隻存量的影響變化與本研究所預估之生產效率的影響變化相當接近，亦也間接支持本研究生產效率估計之結果。
