中文摘要 | 臺灣鰻魚產業在過去幾十年中,由於深受日本消費者之青睞,國內養殖規模不斷擴大,且在產值與產量上,皆居漁產品出口之重要地位。惟1990年以來,由於環保意識抬頭、鰻苗收獲不穩定及中國大陸之競爭,國內鰻魚產業亟需產業創新並提高鰻魚品質以維持競爭力。本文嘗試利用Battese和Coelli於1995年所提出之技術無效率模型,用以推估48家鰻魚養殖戶之隨時性邊界生產函數及其技術效率值,並探討造成養殖業者技術效率差異之因子,藉此評估國內養鰻業者之養殖技術及養殖環境控制能力,以作為養殖戶生產上與政府進行輔導與管理之參考。實證結果發現在5%之顯著水準之下,養殖技術、養殖池齡與自動化系統之有無對鰻魚產業在歷經四、五十年之經驗傳承與研發改進下,生產技術已臻成熟,絕非弱勢產業,且在鰻魚人工繁殖技術即將突破之際,未來鰻魚產業之遠景仍然看好。 |
英文摘要 | Following the lead of Battese and Coelli(1995), the stochastic production frontier model has been used in this analysis. the production frontier of Taiwanese eel industry was estimated first, then the efficiency for each individual eel farm has been generated. Through the specification of the technical inefficiency model, the factors that may affect the productive performance are discussed. The cross sectional data of 48 eel farms’ production in the year of 1998 and the maximum likelihood estimation method are employed to estimate the stochastic production frontier of Taiwanese eel industry. The estimated results imply that seed, labor, land, and capital are relative important in Taiwanese eel production, and automation system have significant influences on farmers’ technical efficiencies. The results also show that farmers’ efficiencies lie between 0.8 and 0.9. The average technical efficiency for the sample farms is 0.87. |
