Research On Green Packaging Recycling Pricing Decision

With the development of social economy,people pay more and more attention to environmental protection and green development concept.Green logistics is based on the concept of green development,a kind of sustainable development of logistics activities.The use and promotion of green packaging is a key link in the realization of green logistics.It can effectively reduce the pollution and waste in the process of logistics.Under the background of the new era of Internet,the rapid development of E-commerce makes online shopping become a part of people’s daily life.Express packaging waste has become the main force of new garbage,causing a lot of resource waste and pollution problems.The use of green packaging can reduce the waste of resources effectively and protect the environment better.With the continuous development of new technology,more and more environmental protection materials are used for green packaging.How to effectively recycle green packaging is not only the key problem of the promotion and use of green packaging,but also an important part of improving the recycling system of express packaging in China.This paper mainly studies the recycling pricing of green packaging.In the process of green packaging recycling,we need to make a reasonable pricing of green packaging,promote consumers to return waste green packaging to recycling point,improve the power of consumers to return green packaging,and increase the recovery rate of green packaging.Firstly,considering the situation of single recycler,the profit function of recycler and the scope of decision constraints are constructed to form a single objective optimization model.Combined with MATLAB software tool,the numerical results are calculated.Then considering the situation of multiple recyclers,the Nash equilibrium model is used for pricing analysis.Then considering the situation of multiple recyclers,the Nash equilibrium model is used for pricing analysis.When the Nash equilibrium point is the inner point of the constraint set,it can be obtained by the method that the derivative function equations of the benefit function are equal to zero.When the Nash equilibrium point appears at the boundary of the constraint set,the traditional calculation method is invalid.Therefore,the Nash equilibrium problem is equivalent to the variational inequality under certain conditions,and combined with the variational inequality projection algorithm,so as to overcome the limitations of the traditional calculation method.The main contribution of this paper is to provide a class of methods to optimize the pricing of green packaging recycling.In this process,the numerical simulation analysis shows that: improving the quality or value of green packaging,although it will increase the recycling price of packaging,leading to an increase in the early cost of recyclers,but whether it is a single recycler or multiple recyclers,it will ultimately improve the profits of recyclers.At the same time,it is suggested to promote the situation of multiple recyclers,because in the Nash equilibrium state,the recycling price of green packaging is higher than that of single recycler,which is conducive to consumers returning green packaging and improving the recycling rate of green packaging.
