Supply Chain Coordination of Fresh Products with Government Subsidy in the Live-streaming E-commerce
摘要
Abstract
With the development of economy and change in consumers'shopping mode,live broadcast with goods,as a new sales mode,can expand the sales channels of fresh agricultural products and improve the circulation speed of fresh agricultural products.The Chinese government attaches great importance to the live broadcasting and cargo carrying industry of agricultural products,and has issued a series of policies to promote the development of live broadcasting and cargo carrying industry of agricultural products in recent years.Howev-er,due to the freshness of fresh products and the flow of live fans,the efforts of product preservation and the live broadcast efforts of the host are important factors affecting the supply chain of fresh agricultural products under the live broadcast e-commerce,which greatly affects the circulation efficiency of fresh agricultural products under the live broadcast mode.Under the live broadcast e-commerce mode,there are still some problems,such as une-ven income distribution among supply chain members and insufficient effectiveness of government subsidies.There-fore,how the government should implement the subsidy strategy to improve the level of consumer surplus and social welfare,and how the optimal decision-making of fresh agricultural products supply chain members will change when the government subsidies are adopted are practical problems that need to be studied and solved urgently. In this paper,a Stackelberg game model is established for a supply chain composed of a fresh agricultural product supplier and an anchor,considering the freshness of fresh agricultural products,the price elasticity of product demand,and the efforts of the anchor of live broadcast e-commerce.Aiming at maximizing the profits and social welfare of the fresh agricultural product supply chain,the impact of government subsidies on the mem-bers of the supply chain will be analyzed when the price elasticity of fresh agricultural products is different.A"revenue sharing cost sharing"contract is designed to improve the profits of each member and the surplus of consumers,so as to achieve a win-win situation for all parties in the fresh agricultural product supply chain.Finally,supply chain coordination is achieved by using the supply chain contract theory,and the impact of gov-ernment subsidies on consumer surplus and social welfare is further studied.The decision-making of government subsidies for anchors under the live broadcast mode is discussed,and the forms of subsidies for fresh agricultural products with different price elasticity of demand are analyzed.This provides a theoretical basis for the choice of government subsidy strategy. Our results show that:(1)Under the government subsidy mode,anchors will improve their efforts to obtain subsidies,and the number of anchor fans will increase synchronously.Although suppliers do not receive subsidies directly,their income will also increase with an increase in government subsidy coefficient.At the same time,suppliers will also improve the fresh-keeping efforts of fresh agricultural products.(2)Compared with the model without government subsidies,government subsidies under decentralized decision-making do not neces-sarily improve the income of supply chain members,the level of consumer surplus and social welfare.In addi-tion,when the government subsidizes fresh agricultural products with greater price elasticity,this can improve the profits of supply chain members and consumer surplus,but will reduce the overall social welfare.(3)The"revenue sharing cost sharing"contract can effectively coordinate the fresh e-commerce supply chain,and improve the consumer surplus and the profits of supply chain members.(4)Government subsidies for fresh agri-cultural products with large price elasticity can increase consumer surplus.Government subsidies for fresh agricultural products with small price elasticity of demand can improve the overall welfare of society.Therefore,when the government subsidizes fresh agricultural products,it should consider the impact of price demand elasticity of agricultural products on the subsidy effect.关键词
