Analysis Of Innovation Behavior Of New Energy Vehicle Enterprises Based On Dynamic Control Under Dual-credit Policy

The proposal of the " carbon emissions peak " and "carbon neutral" goals puts forward higher requirements for low-carbon development in various industries.The dual credit policy is an important way to achieve the " carbon peaking and carbon neutrality " goals in the field of passenger vehicles.How new energy vehicle enterprises make innovative decisions,produce products that meet market demand,meet the requirements of the dual credit policy,and strive for significant development and long-term benefits for the enterprise is a question worth exploring.This article mainly uses optimal control models to depict the actual production situation of new energy vehicle companies,and combines consumer behavior effects to provide optimal decision-making reference for monopoly vehicle companies or policy makers.Construct an optimal control model for monopolistic new energy vehicle enterprises to produce a single new energy vehicle,and analyze the different decisionmaking characteristics from two different perspectives: profit maximization and social welfare maximization.We conclude that innovative investment by new energy vehicle companies can bring long-term revenue growth to vehicle companies and help them maintain high fixed prices and high-tech levels.The profit margin of new energy vehicles is affected by factors such as price elasticity of demand,point prices,and innovation investment level.On the basis of the basic model,the dynamic impact of reference quality effects and learning by doing on innovation investment of automotive enterprises is considered.We conclude that the integral price will affect the pricing strategy of monopoly car companies,and the instantaneous investment change rate of innovative research and development is affected by product technology level,reference quality effect,and knowledge accumulation level.Based on the consideration of the reference quality effect,it is assumed that consumers are also affected by the reference price.We conclude that the instantaneous investment change rate of innovative research and development is influenced by the level of product technology,reference quality effect,and reference price effect,and the direction of action of the reference quality effect and the reference price effect is opposite.The goal of not changing the overall trend of decision-making by new energy vehicle companies will not change,but maximizing social welfare can promote vehicle companies to increase innovation investment,improve the technological content of their products,and reduce the price of their products.
