Research On The Stability Of Symbiotic Development Between Manufacturing And Logistics Industry Of Jingjinji Based On Logistic Equation

The integrated development of Jingjinji has been raised to the height of a major national strategy.In 2010 the national 12th Five-Year plan clearly presented to place the integration of Jingjinji region "and the construction of "capital economic circle "as a national regional development strategy.In 2014,at the central economic work conference," Jingjinji collaborative development " and " The Belt and Road","the economic belt of Yangtse River" had been the national three regional development strategy.The first task Jingjinji integration will be faced with is to locate the industrial function in large areas.In a sense,the industrial structure adjustment is the focus of regional cooperation in Jingjinji.Therefore,the integrated development of Jingjinji will have an impact on the development of manufacturing and logistics industry and related enterprises,and then have a greater impact on the symbiotic development between manufacturing industry and the logistics idustry.This paper analyzes the present situation of symbiotic development,symbiotic development mechanism of Jingjinji manufacturing and logistics industry,and considering the environment changes of integrated development of Jingjinji,establishes the symbiotic development model,and analyzes the stability of the model.The main contents of this paper include the following:First of all,based on the in-depth understanding of the Jingjinji integrated development policies and planning,and the existing research of symbiotic development between manufacturing and logistics industry,the paper analyzes the symbiotic environment,the characteristics of population growth and the present situation of symbiotic development between Jingjinji manufacturing and logistics industry under the background of integrated development.Secondly,based on the symbiosis theory and the theory of regional industry linkage,the paper develops the symbiotic development mechanism under the background of the integrated development of Jingjinji manufacturing and logistics industry,including the analysis of framework mechanism and system mechanism which uses the basic method of system dynamics to establish a causal relationship map,and makes specific analysis.Finally,based on the symbiotic development mechanism of Jingjinji manufacturing and logistics industry,using the logistic equation,the paper reflects the quantitative environmental changes of integrated development to the initial symbiotic development model,and establishes the new model of symbiotic development and carries out the prediction of stable point of symbiotic development.Then,this paper analyzes the affecting relationship between stable point and factors,and then draw the conclusion that all factors how to affect the symbiotic stability in different stage of Jingjinji collaborative integration and propose implementation suggestion.
