Study On The Symbiotic Stability Of The Port And The Coal Enterprises

Port and coal enterprises are important nodes in port supply chain.The stability of their relationship is related to the stability of the entire port supply chain.However,it is not enough for each node to simply change its own way of operation.More importantly,how to coordinate the symbiotic relationship between itself and other enterprises and the symbiotic mode,so that the whole port supply chain can develop steadily.Based on this,from the perspective of symbiosis theory,this paper studies the symbiotic relationship between port and coal enterprises and its stability.Based on the symbiosis theory,this paper analyzes the symbiotic relationship and stability of port and coal enterprises,and establishes the topic of this paper.First,the background and the significance of research of this article are explained.At the same time,the rise and development of the theory of symbiosis and the theory of port supply chain are summarized and analyzed from two points at home and abroad,and the technical route and methods of the research are given,the theory of symbiosis,the theory of population ecology,and the stability are expounded.Secondly,the three elements of the symbiosis of the port and coal enterprise are introduced,the symbiotic index is established,the condition of the symbiotic relationship is formed,and the symbiotic model of the port and coal enterprise is constructed with the Logistic model and the Lotka-Volterra model,and the symbiotic model is made from two points without delay.The model is analyzed and its stability is explained.Finally,the symbiotic relationship between Qinhuangdao port and Datong Coal Mine Group is empirically analyzed,and the appropriate development countermeasures and suggestions are given.
