This paper focuses on the phenomenon of “big data killing” implied in e-commerce and discusses how to take the government as the lead to coordinately supervise the price discrimination behavior of e-commerce companies towards loyal customers. First, the four-party evolutionary game model of the government regulatory department, e-commerce platform, e-commerce company, and consumer is built. Second, the stability of the strategy choice of each game subject is analyzed. On this basis, the evolutionary stable strategy in the system based on First Law of Lyapunov is explored. Finally, the influences of key elements on system evolution are simulated and analyzed by MATLAB2021. Results demonstrate that (1) the government supervision mechanism can effectively supervise the price discrimination of e-commerce company based on big data to loyal customers; (2) when the government chooses the strict supervision strategy, reducing the information supervision cost of the e-commerce platform and the strict supervision cost of the government enable the government and the e-commerce platform to coordinate supervision and make the e-commerce company incline to choose the nondifferential pricing strategy; (3) when the government chooses the loose supervision strategy, reducing the information supervision cost of the e-commerce platform and increasing the probability of consumer discovering differential pricing and the penalties for differential pricing of e-commerce company enable the e-commerce platform and consumer to coordinate supervision, and make the e-commerce company incline to choose the nondifferential pricing strategy. The results of this study can provide theoretical guidance for the government and companies to make beneficial strategic decisions in the development of e-commerce.

The students’ classroom well-being of college students has been widely concerned in online education researches. In order to implement effectively online education in colleges and universities, based on person-context interaction theory, this study investigates a theoretical model of the impact of teacher-student interaction, sound richness, sound pleasure, perceived ease of use and perceived usefulness on students’ classroom well-being. By surveying 349 college students receiving online education, the research hypotheses are tested by the structural equation model approach. Research results show that: teacher-student interaction, sound richness, sound pleasure, perceived ease of use and perceived usefulness appreciably improve students’ classroom well-being, the sound richness and the students’ perceived ease of use can moderate the effect of teacher-student interaction on students’ classroom well-being. Finally some pedagogical implications are discussed.

To attract customers and landlords to join the platform is an important problem to be solved when expanding the size of the shared accommodation platform, and subsidy policies have been proven to be an effective approach in many areas of sharing. In order to analyze the strategies of all parties in the subsidy policy of the shared accommodation platform, a three-party evolutionary game model of shared accommodation platform, consumers, and landlords was built. The strategy stability of each game subject was analyzed, and the equilibrium point stability was explored based on Lyapunov’s method. The game model and influencing factors were simulated and analyzed by MATLAB 2016. Results demonstrated that the consumers and landlords were promoted to join the shared accommodation platform by increasing subsidies to consumers and landlords and reducing consumers’ time costs and landlords’ service fees from the early stage to the rapid development stage of the shared accommodation platform; with the increase of the proportion of landlord’s share in expenses and the decrease of the opportunity loss of platform nonsubsidizing, the strategy of the platform gradually evolves from subsidy to nonsubsidy. The conclusions of this study provide guidance for the mature path of the shared accommodation platform and also give suggestions for the development of the sharing economy.

As China’s population rapidly ages, research and discussion on how to better optimize public spaces for the elderly’s health and benefit continue to deepen. This study uses observational surveys and questionnaires to investigate the elderly visitors of Nanjing’s urban parks and explore the impact the parks’ amenity buildings (structures built to provide visitors with conveniences, e.g., shelters and pavilions) has on their health and associated socialization tendencies. Data were collected from ten amenity buildings in ten separate parks to compose a total dataset of 728 activity statistics and 270 valid questionnaires. The study’s results indicate that amenity buildings significantly increase opportunities for older adults to socialize and thereby can increase this demographic’s associated health benefits. The social activities formed around amenity buildings are found to improve social interactions and connectedness among older adults more compared to other age groups. Elderly participation in social activities is also found to positively correlate with environmental characteristics. High-quality landscapes ensure healthy development of social activities within amenity buildings and promote the occurrence and continuation of social interactions. In order of highest to lowest impact on elderly activities, the following factors were identified and scored: amenity building scale, lighting, comprehensive surrounding environment, surrounding amenities, water features, and vegetation. This research also reveals that among existing amenity buildings, there is insufficient support for certain activities and therefore, parks need to be improved to address this deficiency. Overall, this study indicates that under China’s current aging trends, amenity buildings have become an especially important infrastructure within urban public space, and their design trend is to incorporate the dual characteristics of “recreation + society”.

The number of the religious architecture makes up 70 percent of the total of existing traditional buildings in China, in which the largest proportion is the Chinese Buddhist architecture, this paper has been studied in this kind of building. Firstly, the religious background and development history of the Chinese Buddhist architecture is introduced, and this paper puts forward that this architectural form was affected by the ancient folk houses. Compared to Buddhist architecture in other countries, they are majestic in shape and beautiful elaborate in decoration, the whole form and nature landscape melt into one another. Secondly, religious spaces are analyzed, including the location of Buddhist temple, the overall layout and the single building. Most temples were built on the hill, and the Buddhist hall is the center of architectural complex. Single building is very similar, and its position is attached to its status in spatial sequence. Thirdly, the design concept of Buddhist architecture was discovered. It was pointed out that Chinese traditional philosophy, i.e. the view of the nature, determines the space composition inside and outside of Chinese Buddhist architecture. At last, the paper summed up the design of Buddhist architecture and gave a prospect about the way of its future development.
