Research On LSSC Coordination Contract Considering Fairness-concern In Perspective Of CSR

With the development of e-commerce,the logistics industry of China has continued to growth.The logistics service operation cycle has gradually changed,and the demand for specialized specialization has continued to increase.At the same time,since competition in the market is increasing as participants continue to increase,companies continue to strengthen cooperation,and the idea of logistics service supply chain(LSSC)has emerged.At present,with the development of the Internet,the information channels for public to contact with the enterprises are constantly enriching,and people's attention to corporate social responsibility has also increased.In this context,topics about the lack of corporate social responsibility have emerged endlessly.Under the pressure from public opinion,the company met with public opinion internally,meanwhile,accusations and economic will blow.Moreover,other companies in the supply chain will also be affected.Therefore,in the daily operation of the supply chain,corporate social responsibility(CSR)has become a new hot spot.How to balance social responsibility and economic benefits in daily operations has gradually become an issue for LSSC's participation.The thesis summarizes the existing literature related to the logistics service supply chain and social responsibility for the above problems,on the basis of which the two are combined and studied through methods such as mathematical models and game theory.The thesis establishes a two-level LSSC composed of a logistics service provider(LSI)and a logistics service integrator(FLSP).In the process of the supply chain participating in the game,the company considers CSR and establishes a mathematical model based on the newsvendor model.By comparing and analyzing the optimal decision level of centralized decision-making and decentralized decision-making(wholesale price contract)under a rational game,it is concluded that decentralized decision-making will reduce the benefit of the supply chain.In order to find an effective method for supply chain coordination,the paper introduces the cost sharing contract and the combination contract based on cost sharing and transfer payment to verify whether the two coordination methods can effectively coordinate the supply chain.In order to verify whether it has broader applicability,the paper further considers scenarios where LSSC participants have fairness-concern behavior of the supply chain,and analyzes the dominant strategy of supply chain coordination in the context of considering unilateral fairness-concern behavior and considering both parties have fairness-concern behavior.Research indicates:(1)The level of CSR of LSSC participants is directly proportional to the sensitivity of market demand to the level of social responsibility,and inversely proportional to the sensitivity of cost to level of social responsibility.(2)Comparing with centralized decision-making,decentralized decision-making(wholesale price contract)reduces efficiency of supply chain,and cost sharing contracts can make up for part of decentralized decision-making,but cannot effectively coordinate the supply chain.The combination contract based on cost sharing and transfer payment can effectively coordinate supply chain;(3)The results of numerical examples and simulations show that under the wholesale price contract,the profit level of the supply chain will decrease through the increase of the wholesale price;in addition,whether it is considering only one party's fairness-concern behavior or when considering both parties' fairness-concern behavior,based on cost,the combination contract based on cost sharing and transfer payment is the supply chain coordination dominant strategy.
