Abstract

With the failure of the housing market, the scale of urban housing sandwich class grows rapidly. They are residents who cannot afford commercial housing in the city, but whose income exceeds the local security line. Based on the theory of adequate housing rights, this paper proposes a measurement method for the scale of urban housing sandwich class. Combined with econometrics, the system dynamics model of the housing sandwich class scale in Nanjing was constructed. As the basis for parameter value of the model, python and MATLAB was used to crawl relevant data and fit the distribution. According to the results of the simulation, this paper analyses the change trend of the scale of the housing sandwich class in Nanjing under different policy regulation experiments. The study found that the scale of the sandwich class of housing in Nanjing is at a higher level and has a trend of further expansion. It will help to reduce the scale of sandwich housing class by strengthening the regulation of housing market prices, raising the income line of housing security, and increasing the supply of affordable housing. Meanwhile, the development of urban transportation and the reduction of commuting costs will help alleviate the housing problems of the sandwich class.
