中文摘要 | 本文首先敘述臺灣地區近二十餘年來食品消費支出變化的趨勢,其次設定恩格爾 函數實證式來估測所得和社經變項變化對在家和在外食品消費支出的影響效果。實證樣本資 料取自行政院主計處民國八十二年家庭收支調查資料電腦檔,本研究利用估測的恩格爾函數 迴歸係數值,模擬不同所得和社經條件下,每人每年在家和在外食品消費支出變化情形。此 外,設定三種不同所得成長條件,推估預測未來食品消費支出梗概,在所得成長率為4%條件 下,民國一一○年時平均每人每年在家和在外食品消費支出,將分別較民國八十二年的消費 支出水準增加19%和59%。 |
英文摘要 | This paper firstly describe the trends of food consumption pattern in Taiwan druing the periods of 1971 to 1995. An explicit Engel function is specified to estimate the effects of income and socioeconomic factors on per person expenditures of food at home and away from home. The sample data is obtained from the Survey of Family Income and Expenditures in 1993, conducted by Directorate- General of Budget, Accounting and Statistics. The estimated coefficients of Engel function are then employed to simulate the changes in per person expenditures of food at home and away from home resulting from changes in income and socioeconomic factors. In addition, three various income growth rates are assumed to project food spending to the year 2021. Comparing with the base year 1993, under the condition of a 4-percent increase in income, the results indicate that per person spending for food at home and food away from home is projected to increase 19% and 59%, respectively. |
