Abstract
Under different carbon regulatory policies, corporate social responsibility (CSR) activities will have different impacts on the environmental benefits of the supply chain and corporate carbon emission reduction decisions. In this study, we examine a dual-channel closed-loop supply chain consisting of a single manufacturer selling re-products generated from waste products and a single retailer selling new products and consider two settings: enforcing a carbon tax policy or enforcing a subsidy policy. Under each setting, we put CSR into account, construct two models for the retailer to implement or not implement CSR activities, and analyze the decisions obtained under optimal solutions. Through numerical simulation and comparative research, we observe that the carbon tax policy applies to the supply chain where CSR activities are implemented, while the subsidy policy applies to the supply chain where CSR activities are not implemented. Reasonable selection of CSR implementation methods with low-cost coefficients by the retailer is conducive to eliminating profit conflicts among supply chain members. The government should fully consider the decision-making thresholds of supply chain members to ensure the maximum effectiveness of the policy.
Highlights
The annual “Emissions Gap Report” of the United Nations Environment Program found that because of the impact of the COVID-19 pandemic, global carbon dioxide emissions declined in 2020; it is still moving towards the developing direction that the world’s temperature rises will breakthrough 3 ◦ C at the end of the century
To sum up, when new energy vehicle retailers implement corporate social responsibility (CSR), the government subsidy policy applies to the supply chain of new energy vehicles with smaller production scale and less seniority, which can support the development of small and medium-sized enterprises and weaken the profit conflict of members in the supply chain; in contrast, the carbon tax policy applies to new energy vehicle enterprises with large-scale production and more seniority, which is conducive to guiding large enterprises to play their role as industry leaders and expand the market space of new energy vehicles
We analyze the impact of the implementation of CSR activities on the supply chain performance and environmental benefits and obtain the following main conclusions: (1) The carbon tax policy is more conducive to stimulating the retailer’s awareness of social responsibility and guiding retail companies to implement CSR activities. (2)
Summary
The annual “Emissions Gap Report” of the United Nations Environment Program found that because of the impact of the COVID-19 pandemic, global carbon dioxide emissions declined in 2020; it is still moving towards the developing direction that the world’s temperature rises will breakthrough 3 ◦ C at the end of the century. The above pieces of literature have conducted in-depth research on the two carbon regulatory policies and CSR behaviors, but when perusing the above literature, we began to ponder that the decision-making of supply chain companies to invest in CSR and carbon emission reduction is conducive to expanding the market share of products, which leads to both types of decisions being affected by government carbon regulation policies. What is the impact of corporate CSR investment behavior on corporate decisionmaking, supply chain performance, and environmental benefits under the carbon tax policy?. What is the impact of corporate CSR investment behavior on corporate decisionmaking, supply chain performance, and environmental benefits under the government subsidy policy?. This paper compares and discusses the impact of CSR activities on supply chain performance and environmental benefits under two different carbon regulatory policies.
