Research On The Model Construction And Coordination Mechanism Of Tobacco Supply Chains

China's tobacco industry plays an important role in China's national economy and is an important source of Taxation for the country.China is the world's largest tobacco product market.In 2017,it contributes more than 1 trillion and 114 billion 510 million yuan of taxto China government.However,these results were obtained under the barrieradministrational monopoly and high duty cost.With the development of economic globalization,especially the competition's aggravating after joined the WTO,the Tobacco Industry exigently needs the information-managing tools tocongregate the customer information,in order to improve themselves' working power.The supply chain management is centered around the core enterprise.Through the control of information flow,logistics and capital flow,it starts from purchasing raw materials to make intermediate products and final products.Finally,the product is sent to the consumer by the sales network to bring the supplier,manufacturer,distributor,retailer and end user into a whole,which makes the functional network chain structure mode.With the development trend of economic globalization,the competition among enterprises becomes the competition among the supply chains.How to improve the income of the supply chain is an important goal in the modern market competition.The coordination among the members of the supply chain and the optimization of the supply chain will become an important management activity of the modern enterprises.Based on this,tobacco supply chain model with value-added serviceis constructed in this paper,and we research coordination problemsbetween the tobacco supply chain members combined with game theory,economics theory.The main contents are concluded as follows:Firstly:in the context of modern competition,the diversification and individuation of consumer demand makes tobacco manufacturers seek breakthroughs and develop multiple products to meet the needs of the industry.Based on this,this paper constructs a three level tobacco supply chain model of multi manufacturers.The main research is the three level tobacco supply chain composed of tobacco manufacturers,tobacco commercial companies and retailers.The Shapley value method is used to optimize the benefit distribution of the three level supply chain,and a strict theoretical proof is given,and the optimal strategies are obtained through strict theoretical proof.The results show that the overall profit of the supply chain is the highest in the centralized decision-making model,and the income of all parties and the whole supply chain on the supply chain of the decentralized decision-making model are the lowest,and the alliance may be formed by all parties in the supply chain in order to improve their income.After the alliance,the income of the alliance members is improved,but there is a situation of faster growth of the profit of the members who do not participate in the alliance.At this time,the rational individual will withdraw from the alliance in order to pursue greater interests.The state of the alliance is not stable.The use of Shapley value method can not only improve the profits of all the members of the supply chain,but also make the supply of the supply chain more available.Secondly:based on the complexity of today's tobacco supply chainand the lack of related research,this paper builds a three level tobacco supply chain model for multi commercial companies,which analyzes the decision-making process between tobacco manufacturers,tobacco commercial companies and retailers,and gives a strict theoretical proof,and uses the Shapley value method for the coordination between the profit of members of the supply chain.The results show that the overall profit of the supply chain is the highest in the centralized decision-making model.When the income of all parties and the whole supply chain are the lowest,the alliance may be formed by all parties in the supply chain in order to improve their income.But some of the alliance states are unstable,and the stability of the three level tobacco supply chain composed of tobacco manufacturers,tobacco business companies and retailers is the result of the game.Thirdly:Based on the leading position of tobacco companies in tobacco industry,a tobacco companies led supply chain model is constructed.Because of the characteristics of the tobacco supply chain,the tobacco companies occupies a dominant position in the coordination game of the supply chain,so the tobacco companies is the dominant position in this game model,and the retailer is from the attribute position.By setting up different pricing game models with tobacco companies,we have different sales products and demand functions.Through the example analysis,we get the pricing choices of tobacco companies and retail merchants under their respective circumstances,and give corresponding explanations and suggestions.Fourthly:unlike the traditional supply chain analysis of the two level model,a complete supply chain of tobacco sales includes the three levels of the supplier(tobacco factory),the distributor(tobacco companies)and the retailer(sales terminal).By establishing the supply chain model of three level tobacco supply chain,including suppliers,distributors and retailers,this paper analyzes the Nash equilibrium solution to balance the supply chain,and on this basis determines whether the main strategies will maintain the Nash equilibrium solution.It is proved that the basic optimal solution of the supplier's basic inventory is always greater than the Nash equilibrium solution.Therefore,in order to make the system stock reach the most economical,the corresponding compensation mechanism should be set up to adjust the supply and demand structure in the supply chain.In this paper,the corresponding coordination mechanism is designed,and the optimal strategy of each subject can be consistent with the Nash equilibrium strategy by the compensation mechanism,so that the whole system can be optimized.
