The Impact Of Affordable Housing Community On The Price Of Nearby Commercial Housing

In recent years, with the continuous implementation of affordable housing policies, a large number of affordable housing has been built continuously. There is no doubt that affordable housing plays a positive role in solving the difficulties of low-income residents’ problems. However, large-scaled affordable housing may cause the accumulation of low-income families and middle-income families and these residents live far away from the other classes. Furthermore, it may bring the problems such as residential segregation, social isolation. And it may also lower the commercial housing prices nearby. So far, there is no system research in domestic on whether affordable housing has a significant impact on surrounding commercial housing price and what kind of degree it is. Therefore, this study carried out the following researches based on the domestic and foreign literature reviews using the data in Nanjing:Firstly, the housing characteristics are summarized based on the literature review.
