With a long history, large population, rapid economic growth, and major social transformation in recent years and the launch of the Belt and Road Initiative, China has increasingly become an important global player. However, the negative social and environmental consequences of such a fast and extensive economic expansion are becoming significant. A series of measures have been taken to tackle the current problems faced by the country, including the issuing of new laws and regulations, and the most recent is China’s ban on plastic waste imports. However, there is a significant gap between Chinese laws and their implementation. Therefore, more people are putting their hope in a combination of legislation and Corporate Social Responsibility (CSR) to help address the current social and environmental problems faced by the country. This paper discusses the drivers of CSR in China and compares them to the drivers of CSR in the West. The paper also explores the extent to which CSR can make a contribution to solving the sustainable development challenges faced by China and discusses possible solutions if the current CSR pattern fails. Finally, the paper makes suggestions for future research on CSR in China.

This paper explores the connection between corporate social responsibility (CSR) and food safety and how best to promote CSR in Chinese food companies by comparing two groups of food companies, one which had food safety incidents in the previous three years and one which had no food safety incidents during the same period. Managers of 498 food companies in 17 regions of China were surveyed. It was found that companies where the senior management gave higher levels of support and commitment to CSR and companies that had higher levels of CSR engagement had lower food safety incident rates. Motives for CSR engagement by food companies are the expected benefits that might accrue to the company including helping to achieve strategic objectives, improving daily management, ensuring food safety, improving internal cooperation, enhancing food quality, improving employees’ skills at work, increasing employee benefit and improving their morale, and maintaining business integrity. It was also found that the external factors for CSR engagement are consumer demand, as well as pressures from the government and from other companies in the supply chain. Finally, the paper makes a number of suggestions for improvements in policy.

Nowadays, the development of the world shows that building a new countryside is the only way for all countries to move towards industrialization and urbanization. Whether from the perspective of world development or from the perspective of China’s century-old villages, the development of rural agriculture is very important. Rural infrastructure construction is the key measure to promote all aspects of rural development. The purpose of this paper is to analyze the current situation of China’s rural infrastructure construction, study the factors affecting the development of rural infrastructure construction and find out the key reasons, so as to put forward suggestions on rural infrastructure construction and promote rural development. Therefore, this article uses the relevant data of China Rural Statistical Yearbook 2020 to analyze the influencing factors of China’s rural infrastructure. The article divides rural infrastructure into three levels: agricultural production infrastructure, peasant living infrastructure and rural social undertakings infrastructure, and eight indicators are selected for each level. The article analyzes the new indicators system constructed from 24 original indicators using factor analysis. According to the analysis results, the article comprehensively analyzes rural infrastructure construction situation of 31 provincial administrative regions from three levels and comprehensive indicators. Finally, the articled reaches the following conclusions: the overall development of rural infrastructure construction in Jiangsu, Shandong and Henan provinces is the best, while the rural infrastructure construction in Hainan and Ningxia Hui Autonomous Region, Tibet Autonomous Region, Qinghai and other provinces is the worst compared with other provinces.

With the progress of society and the development of economy, people pay more and more attention to education, and traditional teaching methods are gradually unable to meet the modern teaching system. As a leader in modern information technology, virtual reality technology has developed rapidly in recent years, and virtual reality technology has also been introduced into many fields, such as teaching. Based on the immersive and extended characteristics of virtual reality, this paper proposes a virtual reality active visual interaction method based on the visual sensor. Based on virtual teaching, after 3 months of learning, the average, standard deviation, and average standard error of the experimental group’s performance are higher than those of the control group. Compared with the control group, the experimental group’s performance has increased by 8.25%. The difference is statistically significant. Learning significance (P < 0.05), immersive virtual reality teaching has played a significant role in the effect, which can greatly improve the cognitive experience of students and achieve a good learning experience and effect.

Introduction: A well-connected transportation network unites localities but also accelerates the transmission of infectious diseases. Subways—an important aspect of daily travel in big cities—are high-risk sites for the transmission of urban epidemics. Intensive research examining the transmission mechanisms of infectious diseases in subways is necessary to ascertain the risk of disease transmission encountered by commuters.Methods: In this study, we improve the susceptible–exposed–infected–recovered (SEIR) model and propose the susceptible–exposed–infected–asymptomatic infected (SEIA) model. First, we added asymptomatic patients to the improved model as a parameter to explore the role of asymptomatic patients in the transmission of infectious diseases in a subway. The numbers of boarding and alighting passengers were added to the model as two time-varying parameters to simulate the exchange of passengers at each station.Results: The improved model could simulate the transmission of infectious diseases in subways and identify the key factors of transmission. We then produced an example of the transmission of coronavirus disease (COVID-19) in a subway using real subway passenger data substituted into the model for the calculations.Discussion: We ascertained that the number of exposed people continuously increased with the operation of the subway. Asymptomatic patients had a greater impact on the transmission of infectious diseases than infected people in the course of transmission. The SEIA model constructed in this study accurately determined the spread of infectious diseases in a subway and may also be applicable to studies on the transmission of infectious diseases in other urban public transport systems.

Since its discovery in 2019, the characteristics of COVID-19 have also changed, increasing pressure on subway authorities to control the spread of the disease. Most scientific contributions discussed the correlation between the movement of people in the subway and the spread of the virus, and provided ways to control the spread of the virus in the subway. However, in order to balance production and safety under the easing of the epidemic, it is necessary to establish a relatively common method to evaluate the effectiveness of subway epidemic prevention management measures. This paper investigates subway ridership data after the epidemic has eased, taking the subway of Z city as the case study. SEIA model, adapted from the SEIR (susceptible–exposed–infected–recovered) framework, was developed. The model divides infected people into symptomatic infections and asymptomatic infections, and simulates the movement of subway passengers to show the spread of COVID-19 in subways. In this study, the SEIA model was used to simulate the results of the three protection measures implemented by the subway management department of Z city, namely social distancing, reducing station stops and vaccination. The results showed that the measures of vaccination, while the measures of reducing station stops were the least effective.
