A Study on the Determinants of Individual Income Tax, Profitseeking Enterprise Income Tax, Land Tax and Land Value Increment Tax in Taiwan

本文主要收集2006年至2015年間台灣20個縣市之每戶全年經常性收入、低收入戶人口比例、大專院校以上人口比例、都市計劃區人口比例、失業率、從業者身分結構－－雇主比例與受雇者比例等為自變數，以綜合所得稅、營利事業所得稅、地價稅及土地增值稅4項稅收為應變數，使用多元迴歸分析法，探討自變數對應變數之影響，實證結果發現：平均每戶經常性收入及大專以上人口比例對於營利事業所得稅、綜合所得稅、地價稅、土地增值稅稅收實徵淨額有顯著正向影響。低收入戶人口比例對於綜合所得稅及地價稅有顯著正向影響。都市計劃區人口比例對於地價稅有顯著正向影響。從業者身分結構－－受雇者比例對於營利事業所得稅、綜合所得稅、地價稅有顯著負向影響。從業者身分結構－－雇主比例對於土地增值稅有顯著正向影響。 This paper collates data of annual recurring income per household, the percentage of thepopulation in low-income households, the percentage of the population with college/universityeducation or better, the percentage of the population residing in urban planning divisions,unemployment rates, the percentage of employees and employers in the workforce across 20cities and counties in Taiwan in 2006-2015 as independent variables. The data of individualincome taxes, profit-seeking enterprise income taxes, land taxes and land value increment taxesare referred to as dependent variables. A multiple linear regression is conducted to explore theinfluence of independent variables on dependent variables. The empirical findings are asfollows:The average recurring incomes per household and the percentage of the population withcollege/university education or better have significant and positive influence on profit-seekingenterprise income taxes, individual income taxes, land taxes, and land value increment taxes.The percentage of the population in low-income households exhibits significant and positiveimpact on individual income taxes and land taxes. The percentage of the population residing inurban planning divisions shows a significant and positive influence on land taxes.
