Many manufacturers and retailers have cooperated for low-carbon production in various industries. This study examines the role of consumers’ low-carbon preference in this cooperation. We construct four scenarios to investigate the effects of consumers’ low-carbon preference on the market equilibrium of supply chains’ product selection strategy. Based on the game theoretic models, optimal solutions for the two supply chains are derived with different consumers’ preference for low-carbon products. Through the discussion, we uncovered the influence of consumers’ preference on price and demand and the relationship between the influence coefficient of retailers’ promotional effort on consumers’ utility and retailer profits. In addition, given the increase of government’s low-carbon production subsidy, two supply chains will both more likely choose low-carbon production. Interestingly, under the government subsidy, the profit of manufacturer will increase or decrease more than its retailer and the market structure will not change if the two supply chains have chosen low-carbon production.

Environmental behavior has become one of the most important research areas in the field of sustainable development in recent years. Based on 818 papers on environmental behavior in the Web of Science database from 2002 to 2020, this paper uses CiteSpace software to analyze the trends in publication, subject categories, influential authors and journals, countries, and institutional collaborations. The results show that environmental behavior research has steadily increased over the past 19 years and has gradually achieved diversity and intersection in research subjects. The research on environmental behavior is mainly distributed in the United States, China, and European countries, with the United States being the largest contributor in the field and at the center of the institutional collaboration network. The present research hotspots are as follows: the concept of environmental behavior, factors affecting environmental behavior, the dimension division of environmental behavior, and the construction of a sustainable environmental behavior model. The sustainable development, predictive environmental behavior indicators, factors that affect environmental behavior, and the construction of theoretical models of environmental behavior will become future research trend.

In recent years, the continuous progress of industrialization and rapid economic development have brought great pressure to the environment. Local governments have strengthened environmental regulation to protect the ecological environment. In order to measure the current status of human sustainable development, which is the ultimate goal of the sustainable development of society, this paper constructs the Human Sustainable Development Index to assess the human sustainable development of each province in China from 2005 to 2017. In addition, this paper empirically analyzes the direct and indirect effects of environmental regulation on human sustainable development. The result shows that China has made great progress in human sustainable development from 2005 to 2017. Although the provincial rankings of human sustainable development have changed little over the years, the inter-regional gap of human sustainable development is narrowing. Environmental regulation not only has a direct impact on human sustainable development, but also has an indirect impact through technology innovation. In addition, the increase in the proportion of tertiary industry can also improve human sustainable development. In the future, the government should take human sustainable development as the center, strengthen environmental regulation, promote technology innovation and industrial structure upgrading.

With the rapid development of the social economy, human development has been greatly improved. However, the gap between rich and poor still exists, which restricts the further development of society. In order to study the relationship between social security expenditure and human common development, we constructed, for this paper, the Human Common Development Index, and made a regression analysis between social security expenditure and human common development. The results showed that, in China, obvious and remarkable progress has been made in human common development. There were differences between regions—high in the east and low in the west—but the gap between regions was narrowing. There was an inverted U-shaped relationship between social security expenditure and human common development. At present, social security expenditure per capita in most provinces has not reached the inflection point. The Chinese government should pay attention to the important role of social security, optimize social security expenditure, and improve the accuracy and effectiveness of social security expenditure. In addition, the Chinese government should also improve the urbanization rate and promote economic development.

The interaction between social media and government trust has been one of the most critical and dynamic research areas in the field of governance in recent years. In this paper, a scientometric analysis of 668 academic publications published from 2000 to 2018 related to social media and government trust is presented to characterise the intellectual landscape by identifying and visualising the evolution of the collaboration network, the co-citation network, and the emerging trends. The results show that the number of publications in this field has increased rapidly, and it has become an increasingly more popular interdisciplinary research subject. The most productive authors and institutions in this subject area are in the USA, China, Australia, and European countries. In this paper, we identify the most pressing topics of social media and government trust research as represented in the existing literature, which include the relationship between the Internet and governance, the impact of social media on government trust, and the contribution of social media to government trust and mitigation responses. The paper presents an in-depth analysis of social media and government trust research to better understand governance and the directions in this field that have emerged over the past 19 years.
