The rapid development of the new energy vehicle industry is an essential part of reducing CO₂ emissions in the transportation sector and achieving carbon peaking and carbon neutrality goals. This vigorous development of the new energy vehicle industry has generated many end-of-life power batteries that cannot be recycled and reused, which has brought serious consequences for the environment. In order to solve the negative externality problem brought by EoL power batteries, how the government intervenes in the development of the market and guides multiple parties to cooperate in recycling EoL power batteries is a question worthy of deep consideration. In this paper, we consider that the government acts before recycling companies and consumers, and recycling companies and consumers act again according to the policy. First, we examine an evolutionary game model of recycling companies and consumers in the absence of the government and explore their choice strategies in various scenarios. Second, we examine how government subsidies to recycling companies and consumers may change the trend toward positive recycling in different circumstances. This paper compares the effects of government policies on subsidies to recycling companies, subsidies to consumers, and subsidies to recycling companies and consumers. Finally, the paper proposes policy suggestions from the perspectives of the government, recycling companies, and consumers. The conclusion suggests that the market does not guarantee a high return for both parties without government subsidies. It is difficult for recyclers and consumers to cooperate proactively in recycling end-of-life power batteries. Thus, it is found that government subsidies to recycling companies and consumers can maximize social welfare at the lowest government cost. Even though government subsidies are currently targeted at recycling companies, they should gradually be extended to consumers as the industry develops.

This research conducts an analysis of the sustainability of urban agriculture in Shanghai over the period 2010 to 2020, employing the Triple Bottom Line (TBL) concept as a framework to evaluate sustainability across economic, environmental, and social dimensions through the formulation and application of a comprehensive indicator system. Utilizing the Delphi method alongside the Analytic Hierarchy Process (AHP) for determining indicators and their respective weights, this study adopts a methodologically rigorous approach to analysis. The findings reveal an overall enhancement in agricultural sustainability, albeit accompanied by a decline in economic sustainability. Notably, environmental sustainability emerged as a paramount concern, underscoring the essentiality of incorporating environmental indicators within urban agricultural initiatives. The paper addresses significant challenges such as elevated land prices, demographic shifts, and the imperative for more stringent environmental regulations. It advocates for a multidimensional strategy integrating advanced agricultural technologies and cross-sectoral partnerships to bolster sustainability. Furthermore, the study accentuates the necessity of achieving equilibrium among economic feasibility, environmental stewardship, and social equity to pursue sustainable urban agriculture in Shanghai. Additionally, it highlights the critical role of strategic agricultural policy formulation in fostering sectoral resilience and ensuring enduring sustainability.

The high-quality development of China’s green finance is driven by the aims of reaching peak carbon and carbon neutrality, leading to an important impact of emissions trading policies on the profitability and debt burden of China’s listed companies. This paper uses propensity score matching (PSM) and the difference in differences (DID) method to study the impact of carbon emissions trading policies on the profitability and debt burden of listed companies in seven carbon emissions trading pilots from 2010 to 2019. The empirical evidence shows that the implementation of carbon emissions trading policies has increased the profitability and reduced the debt burden of listed companies: (1) Mechanism test shows that this policy can increase the profitability and debt burden of state-owned listed companies by increasing innovation investment. (2) The negative effects of this policy on the profitability and debt burden of state-owned listed companies are more obvious than that of the others. (3) The policy has also significantly reduced the debt burden of competitive companies and the profitability of monopolies. (4) The policy yields a more intense reduction in the debt burden of listed companies in high-carbon emission industries. Finally, this paper suggests that listed companies’ participation in the carbon emissions trading policy be expanded and that monopoly conditions among listed companies are reduced.

Leisure agriculture is an essential part of urban agriculture in Shanghai. However, sustainable development for urban leisure agriculture has reached a critical point. In this paper, we attempted to analyze the sustainability status of 22 urban leisure farms in Shanghai using the IDEA (Indicateurs de Durabilité des Exploitations Agricoles) method for sustainability indicators. From this analysis, we found out that farms’ average sustainability scores were 25.72 on the agroecological scale, 32.5 on the socioterritorial scale, and 46.5 on the economic scale. This proved that urban leisure agriculture in Shanghai has high sustainability at the economic scale, followed by the socioterritorial scale and the agroecological scale. However, the overall sustainability of urban leisure agriculture in Shanghai was low, which indicates that Shanghai’s urban agriculture still needs to be strengthened for sustainability. Thus, this paper concludes with some policy recommendations for the future development of urban leisure agriculture in Shanghai.
