Evolutionary Game and Simulation between Government and Logistics Enterprises Based on High-quality Development of Cold Chain Logistics
High-quality development of cold chain logistics is an important element in the 14th Five-Year Plan for the cold chain logistics industry.The high-quality development of cold chain logistics is of great significance to reduce the loss of agricultural products and food products in circulation,expand the scope of high-quality market supply,promote farmer income increase and rural revitalization,and improve the quality and safety of fresh agricultural products.Despite the rapid development of cold chain logistics in China,there is still a big gap compared with developed countries.By establishing an evolutionary game model between the government and logistics enterprises,we ex-plored the evolutionary stable strategies of both parties in the high-quality development of cold chain logis-tics and carried out simulation with Matlab.The research result shows that under different constraints,there are four kinds of evolutionary stable strate-gies in the game between the government and logistics enterprises participating in the high-quality develop-ment of cold chain logistics,including one excellent stable strategy,one local excellent stable strategy and two inferior stable strategies.The game between the two parties is influenced by multiple factors,among which efficient government regulation,appropriate penalty system,and active participation of the govern-ment and enterprises have positive impact on the system,while cost of government regulation and cold chain logistics have negative impact on the system.In addition,although the government's subsidy on cold chain doesn't have a direct impact on the evolutionary stable strategies,it plays the role as a catalyst in the system,which can effectively stimulate the willingness of logistics enterprises to participate.However,excessive cold chain subsidization will encourage free-riding by the enterprises,and increase the government's financial stress,so cold chain subsidy should be best kept moderate.Based on the above research results,we put forward three suggestions.Firstly,the government and logis-tics enterprises should prioritize the excellent stable strategy and avoid the inferior stable strategy.Secondly,to achieve the excellent stable strategy,the government should reduce the cost of regulation,assist logistics enterprises to reduce the cost of the cold chain,and improve the efficiency of regulation.Finally,the govern-ment should provide cold chain subsidies moderately to stimulate the participation willingness of logistics en-terprises and prevent their free-riding behaviors.In this paper,we provided theoretical basis and practical guidance for understanding and promoting the high-quality development of cold chain logistics,which has important reference value for the government and logistics enterprises to make decisions in the field of cold chain logistics.
