I studied the similarities and differences of public housing policy between European countries and the United States using historic and comparative methods. Public housing policy was put in place in postwar European countries and the U.S. Differences in the policies of these countries were that the European policy intervened in the housing market directly and thoroughly but the American policy intervened in the housing market indirectly by financial and revenue means. The key finding is that housing in P. R. China is an important part of the people's livelihood and the government should not completely pass responsibility for providing it to the market. China should set up its own public housing policy and change the mode of land supply and housing manufacturing. China also should adopt multiplicative means, including direct government investment and encouraging the social anticipation and planning adjustment to guarantee the housing rights of middle-and-low-income households.
