Research On The Formation Mechanism For Low Carbon Supply Chain Based On Evolutionary Game Theory

In recent years, the development of low carbon economy has become a hot spot all over the world, and low carbon supply chain is the important step for enterprises to become low carbon economy. The developed countries have made a long-term strategy for the development of low carbon economy and promoted the construction of low carbon economy vigorously, such as Europe, USA, Japan, South korea,etc. China also attaches great importance to the construction and development of low carbon economy. However,the industrial development for our country low-carbon economy is not mature enough,and the construction and development of low-carbon supply chains are also at an primary stage.In real supply chain, not every company want to participate in the construction of low carbon supply chain, some enterprises want to implement low carbon strategy, some enterprises do not want to implement it. the formation of low carbon supply chain where some enterprises enter, some enterprises exit is an evolutionary process.According to the problems in the construction of low carbon supply chain,such as the willingness and the evolution stability for low carbon supply chain, this article puts forward indirect evolution method and direct evolution method, the possibility of formation for low carbon supply chain is studied with the former, the after is used to research on the fomation and the evolution stability of the supply chain.The factors for the formation of supply chain is brought out deeply, and finally the formation process of supply chain is concluded. The main jobs are discribed detailedly as follows.Firstly, the study for supply chain which is at the preliminary stage is concluded,according to the review of the previous results.Then,the meaning and the methods for research on low carbon supply chain are summarized detailedly.Secondly, On the basis of previous studies,we review the origin and development of evolutionary game theory,the core concepts of which is introduced later, the characteristics of whose model is pointed out,too.In addition,the similarity of the supply and evolutionary game theory is analyzed comprehensively,the logic relation of which is proposed.Thirdly, Why enterprises have willingness for low carbon and whether it can evolve in the process of natural selection is studied by using indirect evolution method and ESS which is the core concept of evolutionary game theory.The willingness for low carbon in this paper is illustrated as a preference parameter,which includes an enthusiastic participation in low carbon building, willing to authorize, sharing of low carbon technology knowledge, willing to accept low carbon management knowledge, comply with low carbon standard, the development of low carbon enterprise culture.The willingness and stability for low carbon is researched on with considing two kinds of enterprises,which are complementary enterprises and alternative enterprises.Fourthly, considering a supply group who has only two strategies,one is "low carbon",the other is "no low carbon",an evolutionary game model is established to research on the formation and stability of low carbon supply chain by using Replicator Dynamic and direct evolutionary game method,the factors of which is analyzed further. Afterwards, the effects of different factors on the selection of low carbon strategy is analyzed detailedly by using MATLAB software, which further confirmed the results of this paper. Finally, some useful conclusions and suggestions are given basing on how to build low carbon supply chain.According to the related research, the affecting factors and formation mechanism of low carbon supply chain are explored, moreover some useful suggestions and policies of how to buili a low carbon supply chain are given. The result shows that this paper has reached the expectant target and it is a scientific basis for low carbon strategy selection and the construction of low carbon supply chain.
