Research On Supply Chain Decision Of Green Agricultural Products Considering Expected Regret And Government Subsidies

Under the important background that the Chinese government advocates vigorously developing green circular economy,realizing green low-carbon and building a resourcesaving society,the concept of "green" has penetrated into all walks of life,and the green concept is deeply rooted in the hearts of the people.For some agricultural enterprises,the cost of completely choosing green production of agricultural products may be high,and the market demand is affected by consumer preferences.In addition,the government not only guides the public’s green consumption concept,but also encourages agricultural enterprises to carry out green development.Combined with practical factors,this paper considers the timing of expected regret and enterprise overconfidence for green agricultural products enterprises to enter the market and compete with ordinary agricultural products enterprises.In addition,the model of green agricultural products enterprises under government subsidies is also considered to explore the impact of government subsidy coefficient on enterprise profits and social welfare.The main contents are as follows:(1)In the case of market competition between green agricultural products enterprises and ordinary agricultural products enterprises,in order to explore the competitive decisionmaking of agricultural products supply chain under enterprise overconfidence and regret expectation,a duopoly enterprise market competition model including ordinary agricultural products enterprises and green agricultural products enterprises is constructed based on Stackelberg model.According to the different choices of expected regret and market entry,this paper constructs four models: no regret + ordinary agricultural products enterprises enter the market first,no regret + green agricultural products enterprises enter the market first,regret + ordinary agricultural products enterprises enter the market first,regret + green agricultural products enterprises enter the market first,compares and analyzes the profits of agricultural products enterprises in four cases,and explores the optimal market entry time of green agricultural products enterprises.Finally,the numerical simulation is established by MATLAB,and the specific management suggestions are given.(2)In the context of "Agricultural super docking",the government gives green supply chain subsidies.In order to promote the green development of agricultural products,the government promotes the greening of agriculture.A three-stage supply chain game model composed of government,green agricultural products enterprises and supermarkets is established.The government is the leader of the supply chain.According to the way of government subsidy,it is divided into three models: government subsidy to green agricultural products enterprises,government subsidy to supermarkets and government subsidy to consumers.Through comparative analysis and numerical simulation,relevant management suggestions are given.This paper discusses the best time for green agricultural products enterprises to enter the market and the Optimal Subsidy strategy of government subsidies.Using Stackelberg game to establish a theoretical model for research,obtain the optimal decision-making of the supply chain,then compare and analyze the optimal solutions of each model and make numerical simulation,and make relevant suggestions and prospects for the shortcomings of the article.Finally,the relevant results can provide theoretical and practical reference for the duopoly market competition between green agricultural products enterprises and ordinary agricultural products and the optimal strategy of government subsidies for green agricultural products.
