摘　　要：考虑碳价波动的特点,研究了风险规避行为对碳排放依赖型工程机械再制造企业生产决策的影响.首先,分别研究了风险中性情形以及风险规避情形,得到了两种情形下新品和再制造品的最优解,进而分析了风险规避行为对最优生产决策和消费者剩余的影响,并基于全生命周期分析法探讨了环境影响.研究发现,风险规避行为既提高了企业实施全部再制造策略的可能性,且在一定条件下也提高了再制造品的产量,但不会改变企业进入再制造市场的阈值;在任何再制造策略下,企业的期望利润和消费者剩余总是随着风险规避程度的提高而降低;经济效益和环境效益的目标总是冲突的.Considering carbon price volatility,this paper studies the impact of risk aversion on production decisions of an emissions-dependent construction machinery remanufacturing firm.Firstly,the risk-neutral case and the risk-averse case are investigated,and then the optimal solutions of both new and remanufactured products for the two cases are obtained.Subsequently,the impacts of risk aversion on the optimal production decisions and consumer surplus are analyzed,and the environmental impact is discussed based on the life-cycle analysis method.It is found that the firm’s behavior of risk aversion increases the possibility of implementing complete-remanufacturing strategy,and also increases the quantity of remanufactured products under certain conditions,but has no impact on the threshold that the firm enters remanufacturing market.Under any remanufacturing strategies,the expected profit and consumer surplus always decrease in the risk aversion coefficient.In addition,the objectives of economic and environmental benefits are always in conflict.
