C2B平台竞价回收博弈研究

C2B platform Game theory research for recycling

摘要:

网络回收商基于C2B网络回收平台回收废旧产品或二手良品并进行再制造以获取利润。由于C2B网络回收平台的竞价回收机制决定了众多回收商之间存在着激烈的竞争，每个网络回收商回收到的废旧产品数量不仅取决于自己所支付的回收价格，还与其他网络回收商所支付的回收价格相关。期望利润最大化是每个网络回收商的竞争目标。本文首先对C2B网络回收平台的运行机制进行研究，并利用最优化理论与非合作博弈理论，证明了该竞价回收博弈满足超模博弈的条件，并存在唯一的Nash均衡。在完全竞争与串谋合作的不同情况中，我们发现了完全竞争情况下的Nash均衡的网络回收价格高于串谋合作下的网络回收价格，并运用数值仿真的方法进行了验证。

Abstract:

Many recyclers recycle waste products or used fine products and remanufacture for profit in C2B network platform. Since the auction collection mechanism of C2B network platform determines there is a fierce competition among the many recyclers, the recycling number of waste products depends on the cost of recycling itself, but also the price of competitors, expected profit maximization is the objective of each network recycler. Firstly the paper studied the operation of the C2B network platform, and proved the bidding games fits the supermodel game by using the theory of optimum and non-cooperative game theory, and the existence of Nash equilibrium. In perfect competition and collusion cooperation cases, we found a perfect competition circumstance of Nash equilibrium of the recycling price is higher than the conspiracy cooperation network cost, and using the method of numerical simulation is verified.
