There are many factors that affect the price of housing, such as the ratio of supply and demand, economic development, changes in the income of residents, and the level and structure of residents' housing. At present, many of these factors are relatively stable, while the impact of transportation infrastructure construction is often the most unstable factor. After the opening of roads and bridges, a large number of residents move away from the city center and choose the suburbs with convenient transportation, but the construction of transportation infrastructure does not support and enhance the house price in general, but only plays a role of transferring the "demographic advantage". Therefore, when considering the influence of transportation on housing prices, population mobility should be taken into account as an important factor, not just the presence or absence of transportation infrastructure under construction or to be constructed. For example, if a suburb near a subway line is to be extended in a more remote direction, the population of the area may decrease rather than increase, which may not necessarily be favorable to housing prices in that area. Population movement is a direct factor affecting housing prices. Transportation infrastructure development is an indirect factor that affects housing prices by influencing population movement. As a whole, the construction of transportation facilities adjusts the price ratio of house prices in each region through the transfer of "population advantage". However, there are factors that also affect the transfer of "demographic advantage" to the extent that they affect the price of housing in each region. These factors include the geographic location of each region, the degree of development, the potential for development, and the cultural landscape. This also plays an important role in the transfer of "demographic advantages". Therefore, in consideration of other factors affecting the price of housing, the study of population movement to determine the future price of each region, rather than from the construction of transportation facilities to determine the future price of each region is more scientific and accurate.
