电动汽车动力电池区块链技术的投资演化博弈

Evolutionary Game of Investment in Electric Vehicle Power Battery Blockchain Technology

摘要:

为促进汽车生产商积极主动投资区块链技术，基于演化博弈理论，构建电池生产商、整车生产商和政府的三方演化博弈模型，探讨政府参与下汽车生产商区块链技术投资行为，分析三类参与主体之间的行为选择及演化均衡状态，并通过仿真模拟区块链技术特征参数和政府参与行为对于系统稳态的影响。研究表明汽车生产商在区块链技术投资系统中的策略选择与区块链技术所带来的额外收益有关；区块链技术带来的优势、政府所提供的间接收益率都能促进区块链技术投资系统较快地趋向理想均衡状态，而技术引进奖励的波动则对这一速度影响较小。研究结果可以为促进区块链技术引入到动力电池回收行业提供一定的理论指导。

Abstract:

In order to promote automobile manufacturers to actively invest in blockchain technology， based on evolutionary game theory， a three-party evolutionary game model of battery manufacturers， vehicle manufacturers， and the government is created to explore the investment behavior of automobile manufacturers in blockchain technology with participation from the government， analyze the behavioral choice， and determine the evolutionary equilibrium state among the three types of participants. And simulate the influence of the characteristic parameters of blockchain technology and government participation behaviour on the system steady state. The study shows that the additional benefits brought by blockchain technology， and the indirect rate of return provided by the government all contribute to the quicker convergence of the blockchain technology investment system to the ideal equilibrium， while the fluctuations in the incentives for technology introduction have less impact on this rate. The study's findings might offer some theoretical direction for facilitating the adoption of blockchain technology in the power battery recycling sector.
