中文摘要 | 本研究主要以內所消費的生鮮漁產品(虱目魚、吳郭魚、白帶魚、鯧魚、花枝、鰆魚、黑皮旗魚、鮪魚、鱈魚、及其他魚類)為研究對象,本研究利用Anderson及Blundell提出的一般動態需求架構來擴展線性近似理想需求體系(Linear Approximate/almost Ideal Demand System: LA/AIDS)模型,建立一般化動態近似理想需求體系(General Dynamic almost Ideal demand System: GD/AIDS)模型,並以概似比檢定決定出最適的動態模式。本研究並求算漁產品需求彈性值,引申其政策上之意義,以作為漁政單位規劃產銷政策的參考。此外,本研也將婦女就業率、季節性變數及消費者健康風險訊息指數納入,探討其對臺灣漁產品消費的影響,並計算漁產品價格與所得的營養彈性,來瞭解國內對不同漁產品營養成份需求的情形。研究結果發現,消費行為的慣性(inertia)及習慣持續(habit persistence)在漁產品消費中扮演重要的角色;漁產品自身價格彈性都小於1,表示漁產品消費缺乏彈性;鮪魚是漁產品消費中較富營養彈性的漁產品;而婦女就業率、季節性及健康風曾息指對部皆漁產品消費有顯著影響。 |
英文摘要 | This study uses the General dynamic almost Ideal Demand System (GD/AIDS) suggested by Anderson and Blundell to build a dynamic demand system model for the fishery products in Taiwan. Likelihood ratio test has been performed to get the appropriate dynamic specification. The result of this study provides a valuable information of demand and nutrient elasticities for fishery products in Taiwan and can be utilized by the administration as guidelines for related regulations. In addition, indices of the concerns for fat and cholesterol information, seasonal variables, and the increased participation of women in the labor force are incorporated to explain changes in fishery product consumption. Results indicate elasticity estimates of fishery products are all price inelastic, nutrient elasticities are relatively large for tunas; several fishery products are significantly responsive to changes in the participation of women in the labor force, seasonal variables, and the fat and cholesterol information. |
