Evolutionary Game of Investment in Electric Vehicle Power Battery Blockchain Technology

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.
