購屋者家庭結構與收入對購屋投資與消費之影響

Impact of the Family Structure and Income of the Purchaser on the Investment and Consumption of Real Estate

房地產有兩大本質，一是消費，二是投資，家庭的住宅需求則受到人口特性、所處的生命週期階段、收入等因素的影響。實證結果顯示，僅有中年單身選擇自住比例較高。不同於以往研究認為，中年人因年齡較長，不論在職階、地位與收入上均較年輕人有優勢，投資房地產的可能性提高。再者，有固定職業者不傾向於自住，此結果隱含有固定職業者較易以房地產為投資標的，因購屋者有固定收入，資金較不虞匱乏，倘投資失敗較不易影響基本生活條件。此外，月收入在12萬以下購屋者，購屋動機越不傾向自住，推測月收入在12萬以下者，購屋面積不大，購屋動機也隱含部分投資成分在內，有利於下次換屋。

Real estate has two major characteristics: as a consumption good and an investment good. Family housing demands are affected by various factors such as demographics, the stage that the current house is at in its life cycle, income, and so on. Empirical data show that middle-aged singles are likely to purchase houses to be their personal residence. This result is not in line with studies that middle-aged people are older and more advantageous in terms of rank, status and income than young people, thus increasing the possibility of investing in real estate. Besides ,People with fixed occupations are less likely to be owner-occupiers, This result show that those purchaser have a fixed income to invest in real estate. Because the funds of purchaser are less scarce. If the investment fails, it is not easy to affect the basic living conditions. In addition, the purchasers with the monthly income less than 120,000 do not tend towards owner-occupancy, It is speculated that the purchasers with a small area house, for the next house replacement, the motivation for buying houses contains investment components.
