Investment into China's real estate industry is expected to see a moderate growth of 5.1 to 7.1 percent in 2018 amid an adjustment period for domestic property market, report said.

During the next year, property transaction will decline, housing price will remain stable and the investment is estimated to increase at a medium and low speed, according to a report released by the China Index Academy in Beijing Wednesday.

Sales area of commercial buildings will drop by 9.3 to 11.3 percent the next year. And the number of newly established houses is expected to increase by 4.5 to 6.5 percent, it said.

In this sense, real estate operators may tend to hold a conservative attitude when making further investment, the report said.

Housing price will remain stable throughout the year due to the dropping sales and policy regulation, it said.

In 2017, the policies concerning real estate market were transformed from decreasing demand to increasing supply, which in turn helped to control the housing prices, it said.

Transaction area of commercial residential buildings in 50 major cities fell by more than 20 percent this year while that of land rose for the first time in four years, up 12.5 percent year-on-year, the report said.

Property giants accelerated to lead the market while middle-sized enterprises became more diverged, suggesting an upheaval in the competitive landscape, it said.

In 2018, the country will weigh more on optimizing economic structure than boosting high-speed growth in economy. And the currency policy may not likely be loosened in short term due to financial regulation and deleverage, it said.

The report added balance between house renting and purchasing is expected to become a long-term norm.
