本文以傳統需求理論為基礎，討論逆需求函數體系中各參數間應具備的限制關係 ；並採用一階微分近似法 (first-order differential approximalion) 導出逆需求函數體 系的實証模型並加入限制式，再利用迴覆似乎無關聯迴歸法 (ISUR) 聯立推估臺灣地區五種 肉品逆需求體系。實證結果發現，五種肉品之自身未受補償數量彈性均呈負數，顯示在所得 及其他肉品需求量不變情況下，某種肉品消費量要增加，則其價格必出現下降; 同時亦發現 在這五項肉品中以豬肉之自身未受補償數量彈性最大，雞肉次之，因此未來政府對肉品的價 格穩定措施，其重點應放在豬肉與雞肉兩項。

　　　　　Based on traditional demand theory, this study identifies constraints to the inverse demand system for Taiwan's meat demand. Firstly, the first-order differential approximation method was used to obtain an empirical model of the inverse demand system with (constraints) for five meats in Taiwan. Secondly, the iterative seemingly unrelated regression method was used to estimate that inverse demand system. The results show that the uncompensated elasticities of quantity for the five meats were negative, which suggests that when income and the demands for the other four meats remain constant, an increase in consumption of one type of meat will be associated with a decrease in price of that type of meat. In addition, among the five meats, pork was found to have the largest uncompensated elasticity of quantity, followed by chicken. According to the findings, the government should lay emphasis on the price stabilization of pork and chicken in the future.
