Abstract:

In the context of subsidy decline, the implementation of the “dual credit” policy will further realize the low-carbon development of the auto market through market mechanism regulation. Under the combined effect of the decline of government subsidies and the “dual credit” policy, it focuses on the changes in the automobile market equilibrium that considers carbon emissions. Specifically, under the two policies, consider how to optimize production, pricing, and emission reduction research and development strategies for fuel vehicles in the automotive market that simultaneously produces new energy vehicles and fuel vehicles, and discuss the decline in government subsidies and the “dual credit” policy for the automotive market. The impact of optimal production, pricing, and emission reduction research and development strategies, and finally an in-depth analysis of the impact of subsidy decline and the impact of the optimization of the auto market under the “dual credit” policy on carbon emissions. It is found that: 1) The impact of the integral transaction price under the “dual credit” policy on the optimal emission reduction R&D investment of fuel vehicles is non-linear. When the decline of government subsidies is low or high, the government should set higher and lower transaction price of points as an incentive for automakers to increase R&D investment in emission reduction of fuel-fueled vehicles; 2) The national target value of fuel consumption per 100 kilometers has an impact on the optimal emission reduction R&D investment and car demand of gasoline vehicles. The impact is non-linear. When the decline in government subsidies is low or high, the government should set a lower and higher target value of fuel consumption per 100 kilometers to increase the demand of new energy vehicles and reduce the demand of gasoline vehicles; 3) The implementation of the “dual credit” policy has made the automobile market increase investment in fuel vehicle emissions reduction research and development when government subsidies have declined. At the same time, the continued decline of government subsidies may lead to a continuous decline in carbon emissions in the automobile market.

Key words: new energy vehicles, subsidy back slope, dual credit policy, emission reduction R&D, carbon emission
