According to relevant requirements of the National Natural Science Foundation of China, the research site is represented by 4 representative communities in Nanchang. Research object inclusion criteria: Community management personnel and residents representatives who are involved in retirement work can support and cooperate with the survey and provide all the information needed for the investigation.

Stratified random sampling was used to conduct a centralized questionnaire and partial discussion. Contents of the questionnaires of community management personnel: including the convenience of community life; contents of questionnaires of individual residents in the community. After data and information were collected, Epidata 3.0 and SPSS 17.0 software were used for data processing.

The author selected 258 managers and part of the relevant representatives to carry out an investigation. The ratio of men and women was 43.80%: 56.20%, and the statistical analysis showed that there was no significant difference between the sexes (2 = 1.102, P > 0.05), and the highest level of high school education was among the subjects, and the occupations were the highest among the workers. There were significant differences between them (P < 0.01), and the results were detailed in Table 1.

According to the results of the survey, it is found that the courtyard style pension mode of Xiao Jin Tai building has more advantages, and six of the ten conditions are the first. They are “very convenient shopping, ideal health care and health care, sufficient conditions for property maintenance, perfect community communication network, perfect spiritual comfort, and construction of electronic system for health management.” secondly, good adaptability for

Bao Jia xiang, compared to Qingshan Lake and Dong Jia yao two communities, in addition to transportation facilities (89.36%, 89.01% respectively) other conditions to be promoted. A comprehensive comparison of the conditions for the construction of pension mode in the four communities shows that there are significant differences in other conditions except for the response ability of the emergency rescue and the nearby public transport facilities. The results are shown in Table 2 (a is convenient, b is less convenient, c is inconvenient).

The results of the resident representative survey showed that in 7 aspects of living form, number of children and monthly income, 65% of them were living with their partners, the monthly income of 57.5% persons was 2000 - 4000 yuan, and the monthly pension costs of the 66% were less than 500 yuan; the 58.5% way to solve the problem was to seek help for spouses and children, and 100% of the subjects were intelligent. Modern communication tools such as mobile phones, elderly machines and telephone watches. The information indicates that there is a good degree of adaptability to the building hospital endowment. The results are shown in Table 3.

According to the results, the author believes that the "Five conceptions and Six features" has a universal adaptability to the community. From the objective reality of the community, we can see that it is densely populated with large areas of public activities and places of entertainment, familiar cultural environment

(family, neighborhood, friends), can better alleviate the social pressure of the elderly and make the elderly feel safe .It provides an ideal environment for their aged care. Wang Xinghang and others have studied this point [5]; the adaptability of this model is also manifested in the family members’ emotional interdependence, the community’s existing resources are fully utilized, and the reduction of serious aging brings Professional pension institutions and the pressure of poor economic individuals.

According to the analysis of the survey results, community managers and some residents are basically in recognition of pension model among community courtyard. There are no significant differences in terms of education level and occupation. The main reasons are as follows: First, these research sites all have a good economic and social basis, especially Xiao jin tai has advantages, such as

convenient shopping, ideal medical and health care conditions, and popularization of electronic communications. Second, the investigated community has actively cooperated with the survey and information collection on the health problems of the elderly and related work over the years and has received more knowledge including pension. Thirdly, the Bao jia xiang community in particular embodies a good neighborhood relationship, which is undoubtedly of positive significance for the development of institutional pensions. Fourth, with the development of social economy and the implementation of people's livelihood projects, hardware facilities including pensions are increasingly convenient [6] [7], such as sound community entertainment and sports venues, medical aid conditions, and more convenient transportation. According to Jiang Xiaopu, elderly people are physically and mentally healthy through participation in fitness and various recreational activities [8].

The author's survey of 200 community resident representatives showed that the pension intentions reflected by the author are basically consistent with those of the above communities, indicating that the venues and objects of “building/institutional” pension selection have certain objectivity and pertinence. The practical application of the model provides a certain degree of protection. The main basis for this is that up to 77% of the residents’ representatives live with their “historic partner” and “living alone”. The majority of elderly people have 1-2 children, suggesting that these conditions are suitable for the model of the old-age pension. This is inconsistent with the survey results of You Xueqin and others. He believes that the elderly in the apartment are happier, but the reasons he explained are considered to be closely related to child support, positive self-evaluation, and good attitude [9]. The author believes that these factors can implement the spatial transfer, that is, from the apartment to the community, the essence of which lies in the cultural factors such as the concept of pension and the value orientation. With regard to personal monthly income and pension expenses, 66% of residents spend less than 500 yuan on pensions. Consumption like this is difficult to adapt to pensions in apartments and professional institutions [10], while community-based pensions are relatively cost-effective Lower, applicable to such a consumer and income group; it is particularly worthwhile to mention that all the investigated objects have modern communication tools specially adapted to the conditions required by the model, which is consistent with the survey of Yu Duchen et al. [11].
