With the yearly increasing market penetration of new-energy vehicles in China, the retirement of power batteries has gradually become a scale, and most of the waste batteries have entered informal recycling channels, which has induced a series of environmental problems. Considering this issue, we introduced the system dynamics (SD), stimulus organism response (SOR), and the theory of planned behavior (TPB) in behavioral economics to establish the environmental economic benefit evaluation model of power battery recycling strategies, and we performed a dynamic simulation analysis on the effect of government subsidy policy, policy advocacy, and other recycling strategies. The results show that: (1) the recovery subsidy policy can improve the formal recycling quantity and economic benefits of recovery, but the effect on the degree of environmental pollution is limited. (2) The combination of environmental awareness promotion strategy and subsidy policy can overcome the shortcomings of subsidy policy and has significant environmental and economic performance. (3) Compared with the benchmark scenario, the formal recycling quantity, the CO emission reduction, and the economic benefits of recovery in scenario 4 (high subsidy-high policy propaganda strategy) increased by approximately 112 %, 208 %, and 223 %, respectively, and the degree of environmental pollution decreased by approximately 65 %.
随着新能源汽车在中国市场渗透率的逐年提高，动力电池退役已逐渐形成规模，且大部分废旧电池进入了非正规回收渠道，引发了一系列环境问题。针对这一问题，我们引入行为经济学中的系统动力学（SD）、刺激机体反应（SOR）和计划行为理论（TPB），建立动力电池回收策略的环境经济效益评价模型，并对政府补贴政策、政策宣传等回收策略的效果进行动态模拟分析。结果表明：（1）回收补贴政策可提高正规回收量和回收经济效益，但对环境污染程度的影响有限。（2）环境意识提升策略与补贴政策相结合可克服补贴政策的不足，具有显著的环境和经济绩效。（3）与基准情景相比，情景4（高补贴—高政策宣传策略）下的正规回收量、CO减排量和回收经济效益分别提高了约112%、208%和223%，环境污染程度降低了约65%。
