将“产量利润效益”三者有机结合，运用系统动力学方法构建了汽车发动机再制造经济性分析模型。运用该模型选取某发动机再制造企业为实证案例，对其经济效益进行了动态仿真分析与模拟。通过分析得出以下结论：目前企业主要依靠三包汽车发动机盈利，大修机和报废机利润率较低，国家应进一步完善相关法律法规和补贴政策，提高废旧发动机的回收率以促进企业产生规模经济效应。

With the combination of production,profits and benefits,this paper proposed a model for the economic analysis of the vehicle engine remanufacturing by adopting Venism of system dynamics to e-valuate and dynamically simulate the benefits of the engine remanufacturing.Based on the model,an en-gine-remanufacturing enterprise was selected as an example to conduct a simulating analysis of its produc-tion,profits per item and overall benefits.It has been concluded that enterprises'profits mainly come from contracting vehicle engines,and the profits from overhauled and scrapped vehicles are relatively low. Therefore,the relevant laws and regulations and policies for subsidies should be improved to increase the rate of recovery so that the scale effect of the enterprise could be advanced.
