The traditional development mode for social and economic progress has resulted in crises and challenges; therefore, various countries have begun to actively explore sustainable development. As a developing country, China has outstanding environmental problems. However, there are not many empirical studies on the influencing factors of sustainable supply chain in domestic enterprises. Therefore, according to the manufacturing industry in China, a hypothesis model of influencing factors of sustainable supply chain management is set up. The sustainable supply chain practice is based on three dimensions: economic sustainability, environmental sustainability, and social sustainability. The influencing factors of sustainable supply chain include internal management cognition, industry pressure, consumer pressure, and government participation. A structural equation model was used to analyze the questionnaire data of 167 enterprises in Beijing, China. The results show that internal management cognition and government participation has a direct effect on the sustainable supply chain management practice, and internal management cognition has a strong positive influence. Consumer pressure and industry pressure have a small positive impact on internal management cognition, while the effect of government participation on industry pressure is very significant.

With the implementation of regulatory policies, some new problems are emerging, such as uneven governance effects, large differences in economic growth, and social welfare inequalities. In order to promote the sustainable development of both the economy and the environment, it is necessary to provide theoretical explanations for the above phenomena. Thus, this paper constructs a theoretical model of social welfare effects based on the Cournot model. Additionally, the scenario analysis method is used to analyze the social welfare effects of environmental control policies from the perspective of market structure and consumer preferences. The findings of the scenario analysis are as follows: (1) the social welfare effect of environmental subsidy policy is greater than the social welfare effect of environmental tax policy when the absolute difference between the external value of environmentally friendly goods and non-environmental goods is less than 7.4 units and (2) the implementation of environmental subsidy policies or environmental tax policies will improve social welfare when the market structure is a completely competitive market and when both of the externalities of environmentally friendly commodities and non-environmental commodities are not the same at intervals (0, 0.335) and (−0.335, 0). We conclude that (1) the government should consider externalities, market powers, and consumer preferences when implementing environmental regulation policies and (2) the government can achieve a trend toward the development of environmentally friendly goods by guiding consumer preferences and harnessing market power.

Purpose: The importance of the agri-food supply chain in both food production and distribution has made the issue of its development a critical concern. Based on configuration theory and congruence theory, this research investigates the complex impact of supply chain concentration on financial growth in agri-food supply chains.Design/methodology/approach: The cluster analysis and response surface methodology are employed to analyse the data collected from 207 Chinese agri-food companies from 2010 to 2022.Findings: The results indicate that different combination patterns of supply chain concentration can lead to different levels of financial growth. We discover that congruent supplier and customer concentration is beneficial for companies’ financial growth. This impact is more pronounced when the company is in the agricultural production stage of agri-food supply chains. Post-hoc analysis indicates that there exists an inverted U-shaped relationship between the overall levels of supply chain concentration and financial growth.Practical implications: Our research uncovers the complex interplay between supply chain base and financial outcomes, thereby revealing significant ramifications for agri-food supply chain managers to optimise their strategies for exceptional financial growth.Originality/value: This study proposes a combined approach of cluster analysis and response surface analysis for analysing configuration issues in supply chain management.
