Research On Sustainable Supply Chain Pricing And Emission Eeduction Decisions Under Carbon Emission Policies

Global warming has brought severe challenges to the survival and development of human beings.Making people have to change their production and lifestyle in order to achieve their own sustainable development.Sustainable supply chain management requires companies to pursue economic benefits in accordance with the concept of sustainable development,but also need to consider the environmental and social aspects of the overall coordination of economic,environmental and social benefits,the pursuit of the maximization of the company itself and the overall efficiency of the supply chain,so as to achieve the goal of comprehensively enhancing the competitiveness of the enterprise.This paper aims at the three kinds of carbon emission policies issued by governments of various countries,combining the urgency of corporate social responsibility in real life,comprehensive consideration of the company own environmental protection and the commitment of corporate social responsibilities,and research on the supply chain's respective manufacturers and retailers responsibility awareness,sustainable supply chain pricing and emission reduction decisions.Firstly,we study sustainable supply chain pricing and emission reduction decisions under carbon cap and trading policies.Considering that manufacturer faces the government's carbon emission quota restrictions and conduct carbon trading,manufacturer are the key players in the supply chain to conduct emission reduction R&D investments,and build a decision model in which supply chain members do not have a sense of social responsibility,manufacture has a sense of social responsibility,and retail has a sense of social responsibility.As well as the decision model where retailers have a sense of social responsibility,and solve supply chain members' optimal pricing and emission reduction decisions.The research results show that the increase of awareness of corporate social responsibility is not conducive to the increase of their own economic profits,but can effectively promote the emission reduction of manufacturer;retailer has a greater sense of social responsibility than manufacturer has a sense of social responsibility when the product has a more significant emission reduction effect;From the perspective of increasing socialwelfare,manufacturer has the best effect when they have a sense of social responsibility.Secondly,we will study sustainable supply chain pricing and emission reduction decisions under the carbon tax policy.Considering the manufacturer's investment in carbon emission reduction and being constrained by the government's carbon tax,we build a social responsibility model with different members in the supply chain,and use the inverse induction method to obtain the optimal pricing decision and emission reduction decision of the company,and optimize the model.Make a comparative analysis of the decisions.The results of the research show that as the awareness of social responsibility of manufacturer or retailers increases,the overall profits and social benefits of the supply chain system gradually increase,while the company's own economic profits gradually decrease;when the manufacturer's social responsibility awareness is small,the economic profit of the manufacturer itself is greater than the retailer,whereas the economic profit of the retailer will be greater than the manufacturer.Finally,we study the sustainable supply chain pricing and emission reduction decisions under the carbon labeling system.Considering the market demand for products is a linear function of sales price and carbon emissions,establishing a pricing and emission reduction decision model for members of the supply chain when supply chain members have social responsibility awareness respectively.The result shows that the enhanced awareness of corporate social responsibility will lead to the reduction in economic profits,but it is conducive to promoting the increase in economic profits of other member companies to achieve maximum social welfare;further found that retailer has a more significant role in promoting product carbon emissions and increase social welfare when they have a sense of social responsibility.This study aims at the different mechanisms of different carbon emission policies,and combines the urgency of supply chain members to undertake social responsibilities,and studies the optimal pricing and emission reduction decisions problem for different supply chain members when they have a sense of social responsibility.The conclusions of this paper provide decision-making reference for decision makers in the sustainable supply chain.
