## 2 Literature Review  
In the current research results, there are few articles that take green residences as a separate concept to quantitatively study its spatial and temporal evolution characteristics and driving factors, especially from the perspective of different star levels. Since a green residence is a kind of green building with living function [13], the research results of scholars on the geographical distribution and driving factors of green buildings have reference significance for the study of green residences in this paper. Recently, there are differences in the geographical distribution of green buildings, and this difference is associated with local economic and social development levels, real estate market scale, policy environment, and climate conditions, which have become a growing consensus among scholars. Therefore, this paper mainly introduces the relevant research progress on the driving factors of green buildings. In a number of cases, cities with active economies are more likely to adopt high-quality green buildings [14; 15]. [PERSON] et al. [16] explored the spatial and temporal patterns of green buildings in the US and found strong evidence of the clustering of green buildings in areas with stronger economic performance. Furthermore, economically developed regions are able to attract highly educated and high-income residents with a strong environmental awareness [9], who are more prone to pay a premium for the high-quality and greener lifestyles brought by green buildings [17]. In terms of the social environment, there is a close link between local environmental awareness, demographic factors, residents' income, housing and education level, and the development level of green buildings [18; 19]. [PERSON] et al. [20] carried out a multilevel analysis on the impact of political leadership on green buildings in 591 US cities and found that the local government's support for environmental protection is strongly associated with the adoption of green buildings. [PERSON] et al. [21] reported that there is a close relationship between family income, population, and the pursuit of sustainability in moderate-sized US cities. In addition, some academics [9; 15; 16; 22] also confirmed that the demographic characteristics such as the income, housing, and educational conditions of individuals may also drive the promotion of green buildings. The development level of the local real estate market, in terms of engineering technology, real estate price, and scale, is an important factor in driving green building development [9; 16]. Areas with extraordinary technical levels in terms of construction and lower green building premiums can reduce the barriers to the spread of green buildings [23; 24]. When compared to traditional housing, the sales premium of green residences is one of the factors most concerned by buyers, and a city with a high level of construction technology can effectively reduce the premium of green residences in its region [25]. It should be noted that there is a remarkable correlation between the number of Leadership in Energy and Environmental Design (LEED)-certified projects and the size of the real estate market in the United States [14; 22], but the performance of the scale of the real estate market on the green residence development may not be significant in China [26]. A city's capacity to implement policies, in terms of both public incentives and mandates, is an important factor in driving green building initiatives [18]. [PERSON] et al. [27] empirically concluded that mandatory external policies would urge companies to implement green management strategies. [PERSON] et al. [28] studied the green building market in Greece and found that insufficient policy incentives had hindered the promotion of green building. [PERSON] et al. [29] recommended that compulsory and incentive policies should be together in the development of the green building sector in Metro Manila.
