One of the main causes of increasing inequality is due to the change of family structure into nuclear family. Past research had paid attention on the decomposition of income inequality in Taiwan, while few studies had discussed the extent to which increasing income inequality may affect household consumption behavior. Therefore, this study attempts to investigate the distinction between high and low inequality areas in the final average expenditure of nuclear households, and also to analyze how the social-economic characteristics influence household consumption.his study utilized the Survey of family Income and Expenditure in Taiwan in 2006. The initial data is 13,776 households, and the final sample is 6063, distinguishing nuclear household from the others. OLS and Tobit model are commonly employed when it comes to the average consumption of nuclear households. However, these two models only show the analysis on average, and fail to explain the distributional effect. As an alternative, this study estimate a quantile regression model to analyze the effects of exogenous variables on the distribution of the household consumptions. Results show that household average expenditure in high inequality area are greater than in the low inequality for food expenditure, alcohol drink expenditure, and travel expenditure. That is, these three consumption expenditures increase significantly in high income household of the high inequality area. In addition, these three consumption expenditures have positive effects at high quantiles, indicating that the expenditure will increase in the high consumption household of high inequality area.目 錄次試委員審定書 i 辭 i 要 iiibstract iv一章 緒論 1一節 研究動機 1二節 研究目的 4三節 論文架構 5二章 相關文獻回顧 7一節 背景 7二節 所得不均與消費需求相關文獻探討 10三節 小結 12三章 實證模型 13一節 最小平方法 13二節 分量迴歸模型 14三節 Tobit模型 17四節 受限制分量迴歸模型 20四章 資料來源與處理 23一節 資料來源 23二節 資料處理與變數選取 25五章 實證結果分析 32一節 總消費支出 32二節 食品消費支出 39三節 酒精飲料支出 44四節 菸草消費支出 48五節 衣著消費支出 53六節 保健與醫療消費支出 57七節 旅遊消費支出 61八節 娛樂消費支出 65六章 結論 70一節 結論與建議 71二節 研究限制與未來研究方向 72考文獻 73錄一：核心家庭商品總支出與變數之分量迴歸圖 76application/pdf1564851 bytesapplication/pdfen-US家戶消費所得不均Tobit模型分量迴歸模型受限分量迴歸模型household consumptionincome inequalitytobit modelquantile regression modelcensored quantile regression model[SDGs]SDG1[SDGs]SDG10thesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/182309/1/ntu-98-R96627022-1.pdf
