技术创新背景下电子废弃物处理商的竞争博弈

On a Competitive Game Model of E-waste Processors under the Background of Technological Innovation

为探索电子废弃物处理商之间竞争优势,构建了两处理商间的竞争博弈模型。分析了技术创新因素对处理商竞争优势获取的影响,并利用数值仿真对技术溢出率、回收竞争系数、居民自愿返还数量这三个因素对竞争优势的影响做进一步分析。结果表明:引入技术创新有利提升回收价及回收量,然而竞争优势获取与否由技术溢出率的大小所决定,当技术溢出率较高时,处理商的回收量随之增加,对创新实践者而言无法取得竞争优势。当技术溢出率较低时,技术创新实践者相比竞争对手可获得更高的回收量和利润。

In order to explore the competitive advantage among e- waste processors,a duopoly game model related with the two processors is established. With the introduction of the technological innovation,this article analyzes the process of how to achieve the competitive advantage from a static game to a dynamic game. And the effects of technological spillovers＇ rate and the recycling coefficient of the competition on processors＇ pricing decision are researched with the numerical simulation. The results show that the technological innovation is conducive to the increase of the recycling price and quantity. Whether the processor can achieve a competitive advantage through technological innovation depends on the technological spillovers rate. The higher the technological spillovers rate is,the higher the recycling price and quantity will be. But,the innovation practitioner can＇t achieve the competitive advantage. The lower the technological spillovers rate is,the more competitive advantage innovation practitioner can achieve.
