According to the policy recommendations concerning remanufacturing in “Regulations on collection and dismantling management of discarded vehicles”, this paper studies the cooperation decision-makings for used vehicle collection and dismantling between an automobile manufacturer and an automobile dismantling provider. According to the substitution relationship between demand for the new and for remanufactured automobiles, game models of four cooperation modes between the two parties are constructed, and the remanufacturing effect, environment impact and the two parties' profits of the four cooperation modes are compared and analyzed. It is found that the yield and the rate of remanufactured vehicle dot not always increase in the deep collaboration circumstance; when the manufacturer does not provide technical support, automobile dismantling according to the requirements of remanufacturing will improve the environmental effect of both the collection and dismantling process and the two categories of cars; the implementation of “Regulations on collection and dismantling management of discarded vehicles”will reduce the profits of the automobile dismantling enterprises; however, the two parties' deep collaboration can be ensured by compensation strategies under certain conditions.
