Chen Jie, director of the Housing and Urban-Rural Construction Research Center of Shanghai Jiaotong University, believes that some houses are vacant and the housing market is fluid. It is impossible to live in every suite all the time, especially the rented house must be vacant objectively to maintain the ability to update, maintain and accept new population.
This part of the vacancy rate can be called "natural vacancy rate". In addition, with the continuous improvement of people's lives, some properties used for tourism and vacation can't actually live in real time.
On the other hand, too many vacant houses are a waste of resources.
In Chen Jie's view, some houses are vacant, on the one hand, because the holding cost is low, and on the other hand, because the current rental market still needs to be improved, and the rental-to-sale ratio in some cities is relatively low.
Zhao Xiuchi also mentioned that there are many reasons why houses are vacant. Usually, the reason is that the supply of houses exceeds the demand, and there is an inevitable vacancy period in the process of buying, selling and renting houses, that is, "the time lag between supply and demand"; Third, with the improvement of living standards, the emergence of family vacation and leisure rooms leads to the vacancy of their own houses, and renting houses for children to go to school, and their own houses may also be vacant.
According to international practice, 5% is a moderate vacancy rate, and the vacancy rate of commercial housing is between 5%- 10%, which is a reasonable vacancy range, which is conducive to the healthy development of the national economy. The warning line to control the vacancy rate of the international real estate bubble is 10%. Some measures should be taken to increase the sales of commercial housing to ensure the normal development of the real estate market and the normal operation of the national economy. The vacancy rate is between 10%-20%, which is a vacant danger zone; The vacancy rate above 20% is a serious backlog of commercial housing.
Zhao Xiuchi said that in theory, the vacancy rate can be understood as oversupply of housing and vacant houses. However, a certain vacancy rate also shows that the housing level of residents has improved, which is a better performance of living life.
