Zhang Dawei, chief analyst of Zhongyuan Real estate, believes that the tightening of real estate credit is the main reason for the cooling of the market. In the third quarter, the bank lending cycle is generally more than 3 months, and some cities even need more than 6 months. The queuing phenomenon of housing loans in some hot cities in East and South China is serious, affecting the transaction of the real estate market. Zou LAN, director of the financial market department of the people's Bank of China, said recently that the amount of individual housing loans in the first three quarters remained stable, basically matching the amount of commercial housing sales in the same period. Among them, house prices in a few cities have risen too fast, the investment of personal housing loans has been constrained, and the rising speed of house prices has been restrained. After house prices stabilize, the relationship between housing loan supply and demand in these cities will also return to normal. Recently, Evergrande and other individual real estate enterprises have a debt crisis. Many people in the industry believe that this is also a reason for the decline of market trading volume. In this regard, Zou Lan said that the problems of Evergrande group are individual phenomena in the real estate industry. After the macro-control of real estate in recent years, especially after the establishment of the long-term mechanism of real estate, the land price, house price and expectation of the domestic real estate market remain stable, most real estate enterprises operate steadily, the financial indicators are good, and the real estate industry is generally healthy. Fu Linghui, spokesman of the National Bureau of statistics, said on October 19 that since this year, by improving the long-term mechanism of the real estate market, curbing unreasonable demand, promoting the stable release of rigid demand, and restricting some real estate enterprises from blindly expanding by borrowing, the real estate market has generally stabilized, and real estate investment, sales and house prices have gradually stabilized. In the next stage, with multi-agent supply, multi-channel guarantee, simultaneous purchase and rent, the housing system continues to be improved, the market subjects tend to be rational, and the real estate market is expected to maintain stable development. In the first three quarters, the added value of real estate increased by an average of 4.8% in two years, down 1.3 percentage points from the first half of the year. On the whole, the impact of real estate on economic growth is limited. (outlook new era)
