Research On Symbiotic Mode Of Manufacturing Enterprises And Logistics Enterprises Based On Stackelberg Game Model

With the deepening of specialization,many logistics enterprises have emerged.In the face of increasingly fierce competition,more and more manufacturing enterprises outsource their logistics to multiple logistics enterprises,and form a symbiotic relationship of mutual trust,risk sharing and revenue sharing through the mutual exchange of information,technology,talents,capital,etc.Because of the different symbiotic relationship between manufacturing enterprises and logistics enterprises,there will be a variety of symbiotic mode.Different symbiotic mode has different effects on product pricing and profit of manufacturing enterprises and logistics service level and profit of logistics enterprises.In addition,the intervention of logistics platform affects the symbiotic mode between manufacturing enterprises and logistics enterprises.Therefore,the study of symbiotic mode between manufacturing enterprises and logistics enterprises has important practical significance for the symbiosis development of manufacturing enterprises and logistics enterprises.Based on the systematic review of relevant literature at home and abroad,and the definition of symbiosis and symbiotic mode of manufacturing enterprises and logistics enterprises,the symbiotic mode between manufacturing enterprises and logistics enterprises and the symbiotic mode between manufacturing enterprises and logistics enterprises under the intervention of platform are studied by using game theory.First,the symbiosis system composed of single manufacturing enterprise and double logistics enterprises is constructed and four symbiotic modes are studied.The total profit,product price,product demand and logistics service level of symbiosis system under different symbiotic modes are compared and analyzed.It is found that the order of the total profit,product demand and logistics service level of symbiosis system of manufacturing enterprise and logistics enterprises in various symbiotic modes are manufacturing-dual logistics enterprises three party discrete symbiotic mode,manufacturing-single logistics enterprise and logistics enterprises symbiotic mode,manufacturing enterprise and dual logistics enterprises symbiotic unit symbiotic mode,nonsymbiotic mode.Secondly,considering the symbiotic mode between manufacturing enterprise and logistics enterprises under the platform intervention,a comparative analysis of different symbiotic modes is made,and a comparative analysis of the symbiosis system composed of manufacturing enterprise and logistics enterprises before and after the platform intervention is made.It is found that the total profit,product demand and logistics service level of symbiotic system in various symbiotic modes between manufacturing enterprises and logistics enterprises under the platform intervention are in the order of manufacturing-platform-logistics enterprises four party discrete symbiotic mode,platformmanufacturing enterprise symbiotic unit and logistics enterprise symbiotic mode and manufacturing enterprise and platform-dual logistics enterprises symbiotic unit symbiotic mode,manufacturing,logistics enterprises and platform-single logistics enterprise symbiotic unit symbiotic mode,nonsymbiotic mode.The order of the total profit,product demand and logistics service level of symbiosis system under the symbiotic mode of platform-manufacturing enterprise symbiotic unit and logistics enterprise symbiotic mode and manufacturing enterprise and platform-dual logistics enterprises symbiotic unit symbiotic mode depend on specific critical conditions.After the platform intervention,the logistics service level of the symbiotic system composed of manufacturing enterprise and logistics enterprises is improved.However,only when the parameter value meets a certain range,the manufacturing enterprise and logistics enterprises can obtain higher profits than those without the platform.
