In 2009, house prices in major Chinese cities rocketed by as much as 60 percent. This has two main implications for house prices. First, if the housing bubble is not controlled, it could potentially cause a financial crisis in China because of increases in non-performing loans and bankruptcies, thereby affecting the sustainable development of the Chinese economy. The second implication is that high house prices will exclude ordinary Chinese, especially the medium and low-income people, from the housing market as houses become unaffordable. This will further increase inequality in China, which is a big issue in Chinese society, as it can potentially trigger social and political instability.
The government is aware of this problem. Its first policy document in January 2010 contains specific policy options to contain house prices. First, it urged city governments and industry to gear up construction of low-cost economy housing. Secondly, it required a minimum down-payment of 40% for purchases of second homes. These and some other policy directives will certainly have a short-term effect.
But, the policy still does not specify clear long-term development goals for the housing market. My view is that China has a huge population so the demand for housing is not going to go away. As income increases, people will continue to buy houses. Therefore, without clear objectives, a short-term housing policy may only work to a certain extent. To have a sustainable development of the Chinese housing market, one must have a clear-cut policy for the long-term. For example, houses should be divided into different categories and sizes. So, local government and firms could be legally bound to not only build large houses, but to focus more on medium and small-size homes, because the majority of the Chinese population can only afford these, while only the well-off people can afford the big houses. Due to land shortages and environmental constraints, good housing policies should actually not encourage people to buy big houses, or more than one house for one household. This kind of policy will also make sure Chinese society will not be divided any further.
However, to achieve this goal, a very clear tax system must be designed and implemented. For example, owners of bigger homes, those of more than 150 square metres, must bear more taxes, while buyers of small houses (less than 70 square metres) should receive subsidies rather than be taxed. Secondly, people who buy two or more houses should also pay more taxes. Only when such an economic incentive system is implemented can the market be stable and sustainable. But currently, this kind of policy is very difficult to implement because of the dilemma between the need to contain home prices and to ensure social equality, and the need of local governments to raise local revenue. In 2009, for example, the Beijing Municipal Authority realised revenue of 200 billion RMB — 45% of which (90 billion RMB) came from selling land. The over-dependency on selling land for revenue is a major cause of high housing prices in Beijing and other big cities.
