中国高铁开通地级市的房地产投资空间格局分析

In recent years, the construction of high-speed railway in China has promoted the spatial agglomeration of manufacturing industry and productive service industry. Aiming at the problem of whether China's high-speed rail construction will also promote the spatial agglomeration of real estate industry, this paper analyzes the mechanism based on the theoretical model of new economic geography, uses the data of national high-speed rail trains in 2007-2017, uses the dynamic spatial autoregressive model (SAR) and spatial Doberman model (SDM) to conduct empirical research, and obtains the following conclusions: the rapid development of China's high-speed rail has changed the real estate market The market potential and the spatial pattern of real estate investment appear the phenomenon that the real estate investment gathers to the core city and overflows to the medium and small cities at the same time. The improvement of transport infrastructure such as high-speed rail in the region will promote the agglomeration of industry, population and real estate investment in the region; the improvement of transport infrastructure such as cross regional high-speed rail will promote the spatial flow of industry, population and real estate investment. The overcrowding effect of the real estate industry in the big cities will force the real estate investment to spread from the core big cities to the small and medium-sized cities along the high-speed rail; for the small and medium-sized cities with advantageous local resources, the opening of high-speed rail accelerates real estate investment to overflow into their space.
