The national standards for T-bolts are as follows: T Bolt,Hammerhead T Bolts,Harden T Slot Bolt,Hex Head Flange Bolt Suzhou Gubao Screws Co.,Ltd. , https://www.gbscrewes.com According to statistics, in the first half of November, the number of signings for new commercial residential buildings in Beijing was 3911, with an average daily contracted volume of 391 sets, which was 23.6% higher than the average daily contract for new homes in October, and even appeared to be in short supply. However, the real estate inventory in the third and fourth tier cities may have collapsed due to the day-to-day collapse of prices, especially in Wenzhou, which has been leading the decline in national housing prices for two consecutive months since September.
“Because of the economic development level of each region, the composition of the customer base for purchases, and the dependence of the local economy on real estate, etc.†said Guo Yi, director of institutional marketing at Yahao. First-tier cities such as Beijing attract international purchasing power. Third-tier and fourth-tier cities are mainly based on geographical customers.
However, Zhang Dawei, director of the Central Plains Real Estate Market Research Department, questioned the data. "Some reports mentioned only one set of data, namely, the pressure on individual cities' inventory." Zhang Dawei said that the gap between big cities and small and medium-sized cities is not an ice-and-weather phenomenon. From the perspective of the mainstream market, they have all come out of a low point. The state of recovery is not the same as the stage of recovery. In addition to Wenzhou and other southeastern coastal cities, there are generally very few price cuts. He pointed out that housing prices in most third-tier and fourth-tier cities have mainly declined slightly, which is smaller than the decline before the first quarter. However, the heat of the first-tier cities is also compared with the previous, do not use the heat of the first-tier cities to contrast the cold in the third and fourth-tier cities.
In the context of big differences between big cities and small and medium-sized cities in the real estate market, the industry is currently controversial about the status of the Chinese real estate market. At the same time, there are different views on the judgment of the future property market.
“The rising trend of housing prices in first-tier cities is irreversible,†Guo Yi said. For the real estate market, it is the value that can be maximised by the resources it can occupy. The more resources, the greater the value. For the third and fourth tier cities, business, medical care, education, etc. are largely unable to compare with the first-tier cities. "Therefore, from the perspective of China's real estate market, this bipolar development will occur for a long time."
Although the trend of polarization will continue for some time, the introduction of a series of measures such as the protection of housing will have a certain degree of restraint on housing prices. It is understood that from 2009 to the end of 2011, a total of 21 million sets of urban security housing have been built in the country, and basically 11 million sets have been built. The coverage of affordable housing has increased from less than 4% in 2008 to 11%. Zhou Biwen, director of the Beijing Institute of Technology Institute of Real Estate, said that the future trend is mostly "steady." Do not soar, nor should it be a good trend in the development of the property market.
