依據天津市於改革開放後（1978年~2010年）農業投入產出資料建立了隨機邊界生產函數模型，並對天津農業生產效率進行了測算和分析。研究結果發現天津的農業增長主要依賴流動資本的投入，另因天津市地理環境因素，溫度高低及降雨量多寡在農業生產效率中也具有關鍵影響力，農業生產技術效率水準隨時間增加有逐漸提升趨勢，政府財政支農及農業貸款的數字逐年提升，但研究結果顯示政府財政支農金額及農業貸款對於天津農業生產效率無影響。 / Based on the agricultural input and output data from Tianjin City after the reform and opening (1978~2010), a random marginal productivity function model was built. And tests and analyses regarding the agricultural production efficiency in Tianjin City were performed. According to the research results, the agricultural growth in Tianjin City mainly depended on the input of current capital. In addition, due to the geographic and environmental factors in Tianjin City, temperature and rainfall both played an important role in the agricultural production efficiency. The agricultural production technology level had been increasing with time. The amounts of the government’s financial support for agriculture and agricultural loans had been increasing year by year. However, the research results show that these amounts had no influence on the agricultural production efficiency in Tianjin City.
