As a form of tourism and accommodation, the impacts of many factors, such as economy, society, culture and ecology, on the layout of homestays in different research regions is different [41], and the influencing factors and intensity of homestay spatial distributions in different regions are also different (Table 1). According to the characteristics and conditions of the study area, this paper selected the indicators that were highly representative, easy to obtain, quantifiable, and practical for the analysis and research (Figure 2). The average altitude, forest coverage, excellent air rate, and class A scenic spots were selected for the natural and geographical conditions. The altitude directly affects the local climate, temperature, light, precipitation, and other conditions. The area with a pleasant temperature, moderate light, and less extreme weather was more suitable for the location and layout of the homestay and the operation and development of the homestay [42]; the forest-coverage and air-quality rates were the most direct indicators of the quality of the ecological environment in the region. Compared with other ordinary accommodation formats, consumers were more frequently in pursuit of fresh air, clean water, and a green ecological environment [43]; there was no doubt about the impacts of scenic-spot resources on the layout of the homestays. Most of the homestay business forms were originally developed based on the ordinary accommodation business forms around the scenic spot. The unique natural or cultural landscape can cause considerable competitive advantages to the development of homestays in the region [44]. The higher-quality landscape resources can drive the agglomeration of homestays. Regional economic conditions mainly include regional GDP, total tourism income, tertiary output value, per capita disposable income of residents, per capita living consumption expenditure of residents, and turnover of accommodation and catering industry. A good level of regional economic development means that residents have higher disposable incomes, more diversified living consumption demands and strong tourism consumption demands, which can promote the development of new tourism formats, such as homestays [45]; good regional economic development can ensure the financial revenue of local governments. The government has the ability to promote the construction of local tourism infrastructures and service distribution facilities, has sufficient funds to invest in the development of the tourism industry, and implements more tourism development projects and publicity and promotion activities, which will help to improve the core competitiveness of the local tourism industry [46]; the developed service industry in the regional industrial structure can provide a good industrial environment for the development of homestay businesses. Social development conditions are selected from indicators, such as resident population, urbanization rate, road network density, and total number of tourists. The number of the regional resident population determines the potential market scale of homestay tourism, and stable passenger flow is an important prerequisite for the development and agglomeration of homestays [47]; the process of urbanization is a very important engine to stimulate the growth of social and economic consumption and investment [48]. At the same time, urban residents are facing many life pressures and urban diseases, and the demand for vacation and leisure time is stronger; regional accessibility is the key to the development of the tourism industry. Traffic conditions not only affect the development and utilization of homestays, but are also directly related to tourists' tourism experiences [49]. The healthy development of the homestay industry needs to be backed by convenient traffic basic conditions.
