Since"121"document came on in 2003, our government have implemented a series of policies adjusting real estate in succession. Macro-adjustment for real estate mostly focused on glebe and capital at first, but current macro-adjustment is full-scale, besides glebe and capital, government apply more taxation instruments to adjust real estate. It's no doubt that the core goal of government adjustment is to effect the price of real estate stabilization. Government doesn't expect the price of real estate to fluctuate acutely. However, as a market economy country, Government can only adjust from the two aspects of supply and demand, rather than intervene the price of real estate directly. Therefore, we should pay attention to the amount of real estate developing investment which is the key factor in effecting supply.There are many differences among our cities in the view of the amount of real estate developing investment. Among our developed cities, the amount of real estate developing investment of Beijing is the first, Shanghai is the second. The amounts of real estate developing investment of these two cities are much more than Guangzhou, Shenzhen and other cities. The amount of real estate developing investment of Beijing is 2.78 times of Shenzhen in 2002, while 3.64 times in 2005. Even though in the point of the amount of per capital real estate developing investment, Beijing is 1.937 times of Shenzhen in 2005. So, we should pay attention to the differences of the amount of real estate developing investment among our cities. Thereby this paper introduces the notion of"bionics", thoroughly analyzes how the characteristics of cities—real estate entironment of cities influence the amount of real estate developing investment, construct the index system evaluating real estate entironment of cities, further validate that there are internal relations between real estate entironment of cities and the amount of real estate developing investment by means of demonstration analysis. And based on the conclusion of study, this paper put forward some policy advice for our central government to adjust the real estate market.From the study, I find that in the index system evaluating real estate entironment of cities, the developing level of economic of cities, the service level of medical treatment and sanitation of cities, the living condition of city residents, the amount of fortune that city residents own, the developing level of finance and the degree that finance influences the economic, all of above aspects contribute largely to real estate entironment of cities. Moreover, by means of demonstration analysis, this paper also validate that real estate entironment can effectively explain the alternation of the amount of real estate developing investment. Based on the conclusion of study, this paper put forward some correlative policy advice, including advancing and executing strictly the loan standard provided to the real estate company and consumer, strengthening the intendance and management force of development layout and glebe supply management of cities, enhancing the force of executing the taxation to the real estate company, establishing more perfect guarantee system of city housing, etc. |
