上海市における居住移動プロセスからみた居住用商品房のアフォーダビリティ

This paper investigates the affordability of private condominiums for people in Shanghai. The ability to purchase private condominiums depends on whether the purchaser already owns real estate. In Shanghai, the number of condominiums supplied by private developers has been rapidly increasing in recent years. However, as the prices are about 25 times the average annual household income, it is difficult for ordinary Chinese to move to these condominiums from conventional public/traditional housing. In this study, the relationship between the purchase price of a condominium and the annual household income of the buyer is analyzed using a questionnaire. Questions included the location of previous residence(s), what type of housing respondents preferred, how they received financing for the condominium unit, etc. The results showed that the affordability of private condominiums depends on whether a potential purchaser already owns real estate.
