Unfair for people to pay a real estate tax

A REPORT by the Chinese Academy of Social Sciences advises the government to collect real estate tax. Is it the right time to collect such tax? No, says Beijing Times:

Just have a look at Shanghai and Chongqing municipalities, which have been collecting real estate tax for more than five years. The tax has not helped to increase the supply of houses, failed to stabilize property prices, and has not become a stable tax source for local governments.

That is because China's land is all owned by the State, and a real estate tax has little effect upon the market.
