Abstract:

Due to absence of practical housing standards, the structure of housing market in Chinese cities has been seriously distorted and housing supplies are incapable to satisfy reasonable demands. Therefore, it is of great significance and in emergency to stipulate appropriate standards to guide housing construction and consumption. To this end, this study addressed the issue of housing floor area standard. First, it proposed an empirical framework for analyzing floor area standard, i.e., the problem of determining floor area standard was formulated as an optimization problem of maximizing the utilities of households. Then, it reported an empirical study in Beijing. Using the second-hand apartment house data in the Asian-Olympic Village area, the benefit and cost of households with respect to the size of houses were examined with a hedonic regression approach. It was found that the prices of second-hand apartment houses significantly differed by housing floor areas, and the critical size thresholds were identified by the regression analysis. Based on the results, the standard of appropriate housing size was presented and suggestions were made on the regulation of housing market. Specifically, (1) it would be economically efficient to control the minimum and preferential levels of apartment housing. It is recommended to take 50 m² as the minimum level, and 80 m² for the preferential level. (2) It is recommended to take 50~60 m² as suitable size standard for small families. To encourage stepwise consumption, the government might consider decreasing housing transfer costs by reducing tax or providing stipend for the development of small units.
