China's real estate policies will likely remain tight in the coming five to 10 years, a research report from the China Index Academy said on Friday.

Curbing investment-oriented home purchases will continue to be the major keynote, with the policies restricting the number of purchases and the differentiated mortgage rates expected to remain in place for some time, the report said.

However, China's urbanization process and the gradual improvement in residents' income will still help the industry to achieve sound development in the coming decade, the report said.

The Minister of Housing and Urban-Rural Development Jiang Weixin said at a news conference during the 18th National Congress of the Communist Party of China that the government won't ease real estate policies for the time being. The government also plans to start building about 6 million affordable housing units next year.
