Research On Corporate Social Responsibility (CSR) Investment In Low Carbon Supply Chain Under Consumer Preference

With the improvement of living standards,consumers are more and more concerned about the impact of their consumption behavior on the environment and society.By purchasing low-carbon,green and energy-saving products,consumers can reduce the pollution brought by consumption process,and such changes in purchasing behavior promote enterprises to shift to low-carbon production to a certain extent.From the perspective of enterprises,those who only aim at profit maximization cannot do anything.Enterprises need to fulfill their social responsibilities in the process of product production and sales,including but not limited to the production of low-carbon products and providing technical and financial support for the society.In this thesis,the CSR behaviors of supply chain subjects are studied in different supply chain cycles and different product markets to provide certain reference for enterprises’ production decisions.The third chapter of this thesis studies the market where low-carbon products and ordinary products coexist under the single cycle supply chain.Combined with the dual influence of consumers’ different willingness to pay for low-carbon and ordinary products and CSR preference,this thesis studies the CSR input of manufacturers of low-carbon and ordinary products.The competition and cooperation investment strategies of the two manufacturers were investigated,and the effects of different CSR inputs on product prices,market demand and manufacturers’ profits were investigated.The findings are as follows:(1)Manufacturers’ CSR input is not always conducive to the improvement of supply chain profits;(2)In the cooperative investment mode,it is the best strategy choice to invest in the two products,and the cooperative investment mode can improve the loss of competitive efficiency;(3)When CSR input is conducted for the same product,the profit of supply chain under cooperative input mode is higher than that under competitive input mode.The competitive input mode can be effectively coordinated through revenue sharing-two-way cost sharing contract.The corresponding conclusion is verified by an example analysis.The fourth chapter focuses on the market of only low-carbon products under the two-cycle supply chain.Based on the cost learning effect of manufacturers,a two-cycle supply chain system consisting of a single manufacturer and a single retailer is constructed to study the influence of the CSR investment cycle of retailers on the supply chain decision-making,and to explore the selection of CSR investment mode of retailers.The research shows that: for the whole supply chain,CSR input of retailers is always beneficial.When CSR is invested in both phases,the profit of manufacturers and retailers will be maximized.The profit of manufacturers and retailers increases with the increase of cost learning effect.Cost learning effect and consumer CSR preference weaken the influence of price on profit;The decentralized decision-making model will produce efficiency loss due to double marginalization.Pareto improvement can be achieved through joint revenue-cost-sharing contract and two-part pricing contract,and the supply chain profit can reach the profit under centralized decision-making.Finally,this chapter verifies the validity of relevant conclusions through the analysis of numerical examples.
