In the book titled “Ghost Cities of China,” new project developments with considerably less population and enterprises than available space are referred to as ghost cities. In 2010, the Time magazine published a report titled “Ordos, China: A Modern Ghost Town,” which publicized the term “ghost city” and caused tremendous repercussions. Vacancy rates that greatly exceed this critical value are indicative of low market conditions and low land-use efficiency. The vacancy rate of 5% is generally regarded as the upper limit of the natural vacancy rate. The normal operation of the housing market results in vacant housing. The real estate industry has made a considerable contribution to the process of rapid economic development. China’s rapid economic development has garnered global attention however, the associated social problems cannot be ignored. ![]() Since the reform and opening up phase, China’s urbanization rate has increased approximately three times. IntroductionĬhina’s economy has increased substantially due to the global development. The proposed method can help urban planners by identifying vacant areas and providing building information. (4) The vacancy rate is relatively low in the eastern coastal areas, whereas high in the northeast and western inland areas. (3) The first-tier, new first-tier, and second-tier cities showed the lowest (16.9%), relatively concentrated (20.5%), and highest (21.3%) average vacancy rates, respectively. (2) The urban HVR correlates positively with the three production structures (0.3143) but is significantly negatively correlated with population (0.3841), GDP (0.6139), and urban average housing prices (0.5083). The results revealed that (1) the lowest (15%) and highest (24.3%) HVRs occur in Shenzhen and Nanning, respectively. Based on nighttime light data from the Luojia 1-01 nighttime light imagery provided by Wuhan University in June 2018 and the building data obtained from the Resources and Environmental Sciences Data Center, we estimated the HVRs of 49 cities in China by determining the building areas and considering the floor height. Consequently, the methods for accurately determining the HVR are of great importance. The aforementioned trend is disadvantageous in that it will ultimately lead to tremendous wastage of valuable land that could otherwise be more productively utilized. In recent years, the phenomenon of housing vacancy rate (HVR) has attracted considerable attention, especially concerning unjustified expansions of Chinese cities.
