中文摘要 | 本文首先由國內醫學期刊發表與脂肪及膽固醇有關的文獻篇數,編製健康風險訊息指數,並納入Lewbel需求體系模型進行估計,以獲致油脂需求之自身價格彈性、交叉價格彈性、支出彈性與營養素需求彈性等估計值加以比較分析。其次,根據Lancaster(1966)所提出之消費技術關係式,推估主要油脂價格與支出之營養素需求彈性,以瞭解國人攝取不同油脂營養成份需求情形。研究結果發現沙拉油、豬油、葵花油及椰子油均屬正常則,棕櫚油屬於劣等財。隨著消費者所得提高,將導致國內每人平均之飽和脂肪酸需求量約減少0.094%。此外,健康風險訊息均對豬油及棕櫚油需求量變化百分比產生負面影響。尤以豬油之健康風險訊息需求彈性約-0.58較為顯著。 |
英文摘要 | This study first uses a number of relevant fat and cholestorel articles published by medical journal in Taiwan to measure health risk information indices, and these indices have also incorporated into Lewbel model to estimate demand elasticities. Secondly, methods based on Lancaster’s consumption technology, the nutrient elasticities of edible oils are estimated in order to investigate nutrient demand for different oils among domestic consumers. The empirical results suggested that, soybean oil, coconut oil, lard, and sunflowerseed oil indicated to be normal goods, while palm oil presented to be an inferior good. In addition, the average quantity demanded for saturated fatty acid is reduced 0.094% an increasing in consumer’s income with the passage of time, there is a negative impact on quantity demanded for both lard and palm oil in response to the changes in health risk information, and lard accounts for the most significantly negative nutrient elasticity to health risk information (about-0.58). |
