Three-subject symbiotic evolution relationship of forest and fruit products cold chain logistics system
[Objective]In view of the current situation that the links of the cold chain logistics of forest and fruit products were not closely linked and the participants lacked effective connection and interaction,the realization path of the ideal symbiosis mode of the participants in the cold chain logistics of forest and fruit was constructed to promote the resource sharing and complementary advantages of the participants in the cold chain logistics of forest and fruit,further enhance the market competitiveness of the participants,and realize the symbiosis and mutual benefit of the three,so as to promote the high-quality development of forestry in China.[Method]The Lotka-Volterra dynamic evolution models of the two and three subjects of the cold chain logistics system of forest and fruit products were constructed respectively and the equilibrium points and stability conditions of the two and three subjects under different symbiotic modes were explored.The symbiotic evolution trend of the two and three subjects was analyzed by numerical simulation,and the influence of the addition of cold chain logistics providers on the internal symbiotic relationship of the cold chain logistics system of forest and fruit products was discussed.[Result]It was found that the symbiotic evolution results and equilibrium stability conditions of the cold chain logistics of forest and fruit products were determined by the symbiotic interaction coefficient.The symbiotic mode of the two subjects was difficult to achieve the overall mutual symbiosis due to the constraints of transportation technology and other constraints.The maximum environmental capacity of the two subjects was less than the maximum environmental capacity of the symbiotic evolution of the three subjects introduced by the cold chain logistics provider.The final stable scale of the participants in the cold chain logistics of forest and fruit products reached the maximum model was the three-subject reciprocal symbiosis model.The introduction of cold chain logistics providers significantly increased the scale of forest and fruit product business entities and demanders.The model was the best state of the symbiotic evolution of the cold chain logistics system of forest and fruit products,and it was a true sense of reciprocal symbiosis.[Conclusion]In order to promote the formation of the three-subject reciprocal symbiosis model of cold chain logistics of forest and fruit products,the participants of forest and fruit cold chain logistics should pay attention to innovation and service level while improving their competitiveness.Local governments should take comprehensive control measures to balance the development of various participants and coordinate the relationship;the central government should actively improve the standardization of the market and provide a good external environment to promote the formation of its mutually beneficial symbiotic relationship.
