Where is the weakness of the purchase order?

Chu Tian City News "said that the country now has no less than 14 cities to follow the example of Beijing to introduce a similar rule, in general, are in the current ownership of the state base on the ceiling to buy a new house, individual areas such as Shenzhen is harsh, each family limited to hold two sets." But the purchase order itself also has obvious weakness. One of the soft spots is the concept of time. What is the length of "temporary", one year or two years?　　The purchase itself is a long-term investment, to "temporary policy" on long-term investment is very large. The second weakness is the regional concept. How to define the "hot spot" region, where the government will consider its own urban housing is not normal? Besides, there are more than 600 cities in China, and 14 cities are limited to buy bucket.　　"Limited purchase Order" only to the investment speculative force "temporary" extrusion "hot spot" area, but led to the rise of other areas, and regulation of the original intention of the contrary.　　Real estate control Our economic means used, not to make, administrative means are being used, uncertain, whether to consider the use of legislation means? The root of the housing price problem lies in the increasingly serious polarization of the rich and poor. When 20% of the population of 80% of the assets in the investment speculative attitude into the real estate sector, 80% of the poor in the hands of 20% to solve the survival needs of the capital, how to contend? This is the game of ants and elephants!　　There is no equality to speak of. Because the power to push up prices is that the rich are not the poor, therefore, economic means are not used, and because of the nature of policy expediency, the administrative means will be distorted, and the real estate tax and innocent legislation on the basis of questionable institutional arrangements, legislation against the housing is not only the protection of the poor, but also reflects social equity and justice, but also reduce the cost of living , why not?
