摘要

电动汽车(EV)电池的回收和再利用是延长其有限寿命的方法。如果能对电池从生产到回收的全过程进行追溯,有利于电池的回收再利用。利用区块链技术构建智能电动汽车电池逆向供应链,可以解决缺乏信任和数据的难题。本研究的目的是讨论政府监管下的智能电动汽车电池逆向供应链的行为演化。本研究采用进化博弈论考察政府、回收废旧电池的电动汽车制造商和缺乏专业回收资质的第三方电动汽车电池回收商的决策行为。发现在区块链技术集成的智能逆向供应链中,当政府倾向于主动监管时,第三方电动汽车电池回收商的合作回收策略是最优选择。电动汽车制造商选择区块链采用策略的概率超过(低于)阈值,政府倾向于负(正)监管。数值分析表明,在电动汽车电池回收行业的成熟阶段,当应用区块链的投资成本较高时,电动汽车制造商应用区块链的意愿放缓,政府加速采取负监管策略,第三方电动汽车电池回收商倾向于合作回收。实践意义本研究结果对政府监管力度以及电动汽车制造商和第三方电动汽车电池回收商应在何种条件下实施区块链并进行合作提出了意见。另一方面,本研究为推动区块链技术在智能逆向供应链中的应用提供理论分析。与以往的研究相比,本研究揭示了政府监管、区块链应用和合作策略在智能电动汽车电池逆向供应链中的相关性。在初始阶段,即使补贴(补贴减免率)和罚款高,罚款减免率低,电动汽车制造商也应该放弃区块链技术的应用。在电动汽车电池回收行业的中期,政府可以设置较低的补贴(补贴减免率)结合罚款或较高的罚款(罚款减免率)结合补贴进行监管。建议第三方电动汽车电池回收商在补贴低或罚款高的情况下与电动汽车制造商合作。

The behavioural evolution of the smart electric vehicle battery reverse supply chain under government supervision
PurposeRecycling and reuse of the electric vehicle (EV) batteries are ways to extend their limited lives. If batteries can be traced from production to recycling, it is beneficial for battery recycling and reuse. Using blockchain technology to build a smart EV battery reverse supply chain can solve the difficulties of lack of trust and data. The purpose of this study is to discuss the behavioural evolution of a smart EV battery reverse supply chain under government supervision.Design/methodology/approachThis study adopts evolutionary game theory to examine the decision-making behaviours of the government, EV manufacturers with recycled used batteries and third-party EV battery recyclers lacking professional recycling qualification.FindingsOn the smart reverse supply chain integrated by blockchain technology, a cooperative recycling strategy of the third-party EV battery recycler is the optimal choice when the government tends to actively regulate. The probability of the EV manufacturer choosing the blockchain adoption strategy exceeds (below) the threshold, and the government prefers negative (positive) supervision. According to numerical analysis, in the mature stage in the EV battery recycling industry, when the investment cost of applying blockchain is high, EV manufacturers' willingness to apply blockchain slows down, the government accelerates adopting a negative supervision strategy and third-party EV battery recyclers prefer cooperative recycling.Practical implicationsThe results of this study provide opinions on the strength of government supervision and the conditions under which EV manufacturers and third-party EV battery recyclers should apply blockchain and cooperate. On the other hand, this study provides theoretical analysis for promoting the application of blockchain technology in smart reverse supply chain.Originality/valueCompared with previous research, this study reveals the relevance of government supervision, blockchain application and cooperation strategy in smart EV battery reverse supply chain. In the initial stage, even if the subsidy (subsidy reduction rate) and penalty are high and the penalty reduction rate is low, the EV manufacturer should rather give up the application of blockchain technology. In the middle stage in the EV battery recycling industry, the government can set a lower subsidy (subsidy reduction rate) combined with a penalty or a higher penalty (penalty reduction rate) combined with a subsidy to supervise it. The third-party EV battery recycler is advised to cooperate with the EV manufacturer when the subsidy is low or the penalty is high.
