Research On The Internal Complexity And Coordination Of Green Supply Chain Based On Government Subsidy

In order to cope with the pressure from regulators,competitors and customers,it has become an inevitable choice for enterprises to seek sustainable development and promote green technology to realize product transformation and upgrading.Based on the current research status of green supply chains by domestic and foreign scholars,this paper takes enterprises that continue to invest in green innovation as the main research object,builds a multi-period dynamic game model of enterprises,and studies the inherent complexity and coordination of green supply chains based on government subsidies Using theories and methods of game theory and non-linear systems,the complexity of the evolutionary game of the system is studied,and the influence of parameters and multi-parameter coupling on the stability and evolution of the system is studied.Numerical simulation results verify the correctness of the theoretical model The experimental calculation results make up for the analysis and research work on the stability and dynamic evolution of the system in the case that theoretically accurate solutions cannot be obtained.The specific research content and innovative work are summarized as follows:1.Based on the government's investment in product energy-saving levels under government subsidies,a green supply chain model consisting of two green innovative companies was constructed.Assuming that the decision-making subject in the model is bounded rationality,the pricing stage is divided into a manufacturer-led pricing decision stage or a retailer-led pricing decision stage based on the actual situation.The research results show that the stability of the manufacturer's pricing decision will affect the stability of the retailer's pricing decision.It has a greater impact and conduction effect.Theoretical analysis and calculation experiments have found that the decision-making adjustment coefficient of the decision-maker has a significant impact on stability.At the same time,in order to ensure the stability of the system,manufacturers must not blindly pursue the improvement of the energy-saving level of the product.2.Based on the research of traditional green supply chain,a duopoly multi-period repeated game model considering extended producer responsibility system and corporate remanufacturing behavior was constructed,and the complexity of the model was analyzed.Combining theoretical research and numerical simulation,it can be found that the decision-making adjustment parameters of decision-making subjects have a great impact on stability;the company's investment in product innovation has less impact on the system's stability domain,and has a positive effect on corporate profits and recovery.3.This paper studies the government policies and their effects in different scenarios,and studies the green product subsidy levels and green energy benchmark energy efficiency indexes formulated by the government.The results show that the appropriate stepped policy subsidy levels will encourage enterprises to carry out Energy-saving investments,and overly demanding subsidy standards cannot prompt manufacturers to increase investment in environmentally friendly technologies.In addition,the government's subsidy for the recycling of waste products by enterprises can increase the profit of manufacturers and stimulate the increase of the proportion of recycling waste products.The stability area of this complex system will gradually decrease as the subsidy level increases.4.Based on the great harm of chaos to the system,this paper effectively controls the chaos phenomenon of the system by adjusting the parameters of the decision-making process of the decision-making subject and their parameter combinations.The research results can provide theoretical and practical reference for the operation of the enterprise.
