Looking at tanning lamps from all angles

Housing vacancy rate is a common concern of the public, because this indicator can explain the speculation in the real estate market and is a weather vane to observe the health of the property market. However, this statistical index, which is common in Europe and America, has evolved into the "Goldbach conjecture" of the whole people in China. How many vacant rooms are there in the country? Although the power company chose "aphasia", the National Bureau of Statistics said that it could not be counted, but this could not dampen the enthusiasm of netizens and experts for finding answers. Netizens from all over the country launched a round of folk statistics in the form of "black light", "checking electric meters" and "drying water meters". According to reports, a survey conducted by State Grid Corporation in 660 cities across the country showed that as many as 65.4 million residential electricity meters had zero readings for six consecutive months. The problem of housing vacancy rate once became the focus of debate. But then the State Grid denied this statement. Although the "vacancy rate of State Grid Edition" has not been responded by authoritative departments, a stone has stirred up a thousand waves and caused great repercussions among netizens. The research team led by Professor Zhang Jingqiu and Professor Meng Bin of Beijing Union University investigated the electricity consumption of more than 50 residential quarters in Beijing from 2004 to 2006. The results show that the proportion of rice that hardly goes is as high as 27. 16%.

● Zhang Jingqiu, Head of the Department of Urban Science, School of Applied Arts and Sciences, Beijing Union University;

Check the electric meter to study the vacancy rate with small resistance.

The interval between the two surveys is two months, which is in the hot summer. If there are regular households, they should use a lot of electricity. Therefore, assuming that the electricity consumption of a house is within 10 degree within two months, the house can be regarded as vacant, and the calculated vacancy rate is 27. 16%.

Because electricity meters are generally outdoors, the investigation resistance encountered is relatively small. However, this calculation method of vacancy rate is only the direction of discussion, and it is an investigation method of academic research. Because the sampling range of the survey is not large, its data is not authoritative. Compared with electricity meters and water meters, "drying lamps" can more intuitively reflect the vacancy situation in the property market, which has triggered heated discussion and extensive participation of netizens. Some netizens even said that some housing enterprises urgently transformed lighting to reduce the black light rate. Although the content of the netizen's post can't be confirmed, the statement that high black light rate means high vacancy rate is obviously recognized by an ordinary taxi driver who has worked under an office building in Beijing for a long time. This "brother" named Li Jie took part in the "sunbathing" activity and took hundreds of photos of the dark in the community.

● Beijing taxi driver Li Jie:

High-end residential areas are vacant.

Specially chose the weekend, sacrificing the opportunity to make money. The photo-taking time is 9: 00 pm 9:00- 10/0, mainly in luxury houses and high-end residential areas, and the occupancy rate is about 50%.

● Financial commentator Fang Quan:

The black light rate reflects the vacancy rate to some extent.

Of course, the black light rate is not equal to the vacancy rate, but it reflects the vacancy rate to a certain extent, which is common sense, so the excuses of so-called real estate experts are all nonsense! According to media reports, the latest internal statistics of Hangzhou Water Industry Group show that among the 570,000 houses with water meters in the five districts of Hangzhou, 30,000 are "zero water meters". The staff of Hangzhou Water Industry Group said that these 30,000 "zero water meters" are mainly distributed in more than 20 communities, and there are 17742 households with zero degrees for half a year.

● Senior real estate planner Zhang Huifang:

The way to check water and electricity is more accurate.

It is relatively accurate to check the water, electricity and vacant rooms, followed by air conditioning, but "the light is on or off" does not explain the real problems, such as business trip and late return. In addition, a certain percentage of the vacancy rate is normal, generally between 5%- 10%. At present, the sticker method commonly used in playing cards has also become a method to count the vacancy rate of the property market. A netizen suggested that you go back and put a note on the doors of all your neighbors every week and check it again at the same time next week. The person who didn't tear up the note is probably empty.

● Netizen "Gu Yue Spaceship":

Sticker strips and keyhole plugging are also methods, but keyhole plugging technology is too difficult. A few years ago, commercial housing in Hainan was seriously vacant, resulting in 70% of property companies losing money because they could not find owners to collect property fees for a long time. Yin Zhongli, a researcher at the Institute of Finance of China Academy of Social Sciences, said that there are not only houses that have been built but not sold, but also hundreds of millions of square meters of "closed houses" that have been sold but not used. These vacant houses in the second-hand market are the real macroeconomic killers.

● Yin Zhongli, a researcher at the Institute of Finance, China Academy of Social Sciences:

There are statistics on the use of property.

Every city's real estate management department has a department in charge of property management, with detailed property use registration, and it is very clear how many unoccupied houses there are in each community. But so far, no city has published relevant statistics.
