RESEARCH ON IMPACT OF DUAL CREDIT POLICY ON SERVICE MODE IN NEW ENERGY VEHICLE SUPPLY CHAIN

. Under the dual credit policy, the new energy vehicle industry is faced with the multi-decision collaborative optimization problem of service level, R&D level and pricing under different service modes. This paper aims at the supply chain structure composed of a new energy vehicle manufacturer and a battery manufacturer, and respectively constructs decision models under three service modes: the new energy vehicle manufacturer providing service, the battery manufacturer providing service, and jointly providing service. On the basis of solving the model by using Stackelberg game theory, numerical analysis is used to put forward management suggestions. The results show that under the joint providing service mode, both enterprises can obtain the highest profit, followed by the mode of the new energy manufacturer providing service, while the profits of both enterprises are the lowest under the mode of the battery manufacturer providing service. The government departments should actively increase the credit price under the policy.
