The Study Of Symbiosis Evolution Between Logistics And Manufacturing Industries

Developing the logistics industry rapidly and enhancing the manufacturing level have become the inevitable trend of our national economic development.In reality,the service demand of the manufacturing industry and the service supply of the logistics industry will be misplaced,and the instability of the cooperation relationship will lead to the low efficiency of cooperation between the industries.The cooperation development problem between logistics industry and manufacturing industry has become a major problem hindering the balance and full development of logistics industry and manufacturing industry.Manufacturing industry is the basis of demand for the development of logistics industry,the logistics industry also influence the development speed of the manufacturing industry,the two industries are interdependent,mutually integrated and permeated.Only by promoting the development of the symbiosis between the logistics industry and the manufacturing industry,can we clearly realize the stage of industrial cooperation,achieve effective cooperation between industries,and form a virtuous circle of cooperation.Thus,it is conducive to the formation and development of manufacturing supply chain and the realization of winning industry.This paper takes the symbiotic evolution of logistics industry and manufacturing industry as the research object,combines and establishes a variety of symbiotic evolution models between logistics industry and manufacturing industry based on Logistic model of the symbiosis evolution,discusses the symbiosis evolution relationship between the logistics industry and manufacturing industryin an independent environment and strategic alliance environment,takes Qinghai Province as an example of empirical analysis.Firstly,this paper judges whether there is a symbiotic relationship between the logistics industry and the manufacturing industry.The TOPSIS method is used to deal with all the data of the logistics industry and the manufacturing industry index system without dimensionalization.The VAR model is used to analyze and determine whether there is a symbiotic relationship between logistics industry and manufacturing industry.There is a long-term cointegration relationship between the logistics industry and the manufacturing industry.The symbiotic relationship between manufacturing industry and logistics industry is proved by impulse response function and variance decomposition.It is calculated that there is a symbiotic relationship between the logistics industry and the manufacturing industry in Qinghai province.Secondly,this paper establishes many symbiotic evolution models that may exist in the symbiotic relationship between logistics industry and manufacturing industry under the independent environment of industry based on the Logistic model,calculates the equilibrium points of each model and discusses the stability of its solution.Doing simulation experiment on each pattern using quantum genetic algorithm.The result of comparative analysis shows that the relationship between logistics industry and manufacturing industry is the cooperative symbiotic evolution under the independent environment of industry.The quantum genetic algorithm is used again to estimate the paramaters of the model on the basis of this.It is concluded that there is a cooperative symbiotic evolution relationship between logistics industry and manufacturing industry in Qinghai Province,and it is in the growing stage of symbiotic evolution.So the logistics industry and the manufacturing industry have evolved from a relatively independent environment to a strategic alliance relationship.Thirdly,this paper establishes many models of the symbiotic evolution relationship between the logistics industry and the manufacturing industry under the stragetic alliance environment based on the Logistic extension model.At the same time,this paper discisses the equilibrium point and stability solution of logistics industry and manufacturing industry in the existence of each model.Due to the different share resources of strategic cooperation offered by the logistics industry and the manufacturing industry in the industrial strategic alliance environment.This paper discusses three possible situation: when the resources provided by the logistics indistry are equal to the resources provided by the manufacturing industry;when the resources provided by the logistics indistry are less than the resources provided by the manufacturing industry;when the resources provided by the logistics indistry are more than the resources provided by the manufacturing industry.Doing simulation analysis of each shared resource state using quantum genetic algorithm.Combing the parameters of the equilibrium point and the stable solution of the symbiotic evolution model,obtaining the symbiotic mode of the logistics industry and the manufacturing industry under the background of each resourse.Finally,this paper analyzes the reasons of the low degree of symbiotic evolution between logistics industry and manufacturing industry in Qinghai Province,and proposes some countermeasures and suggestions on how to improve the degree of symbiotic evolution of logistics industry and manufacturing industry.
