Research On Battery Cooperative R&d And Recycling Strategy Based On New Energy Automobile Industry Chain

Since new energy vehicles entered the market,my country has continuously introduced relevant policies to promote the rapid development of the new energy vehicle industry,the production and sales of new energy vehicles have been increasing year by year,and the market competitiveness has gradually increased.However,due to the lack of effective cooperation between enterprises in the new energy automobile industry chain,energy vehicle battery technology has not yet achieved breakthrough innovations,vehicle endurance is still the main factor that inhibits consumers’ willingness to buy new energy vehicles.In addition,with the continuous development of the industry,the derivative problem of the recycling of decommissioned batteries has become more and more prominent.due to the lack of a complete battery recycling system,battery recycling efficiency is low,and it is easy to waste resources and cause environmental pollution during the recycling process.Therefore,battery technology innovation and recycling issues have become two key factors restricting the development of the new energy automobile industry.This paper takes the new energy vehicle industry chain as a research perspective,based on industrial organization theory,game theory,and technological innovation management theories,combined with theoretical analysis and numerical simulation methods,starting from the improvement of the battery quality level and recycling efficiency of new energy vehicles,study the issue of cooperative R&D and recycling strategies between enterprises in the new energy automobile industry chain.First,taking into account consumers’ demand for car endurance and the ability of industrial chain cooperation and innovation,three types of cooperative R&D game models with shareholding including upstream battery suppliers and downstream vehicle manufacturers in the industrial chain have been established.By comparing non-cooperative R&D and shareholding cooperative R&D strategies,it is found that cooperative R&D can more effectively improve the endurance of new energy vehicles,it is a better choice.And the feasibility of the three cooperative R&D strategies was verified,analyzed the optimal scenarios for different cooperative R&D strategies to improve the endurance level,and finally concluded the realization conditions of different shareholding cooperative strategies.Secondly,consider the influence of downstream retailer in the industrial chain on the cooperative innovation of the industrial chain,introduce the retailer into the above game model,study the strategy of vertically integrated shareholding and cooperative research and development.Through comparative analysis of the three integrated cooperative R&D game models,it is found that the two-way integrated shareholding cooperation strategy can not only achieve the highest endurance of new energy vehicles,but also achieve the coordination of the entire industrial chain,which is the optimal cooperation strategy.Subsequently,the paper studied the cooperative recovery contract strategy between the midstream new energy automobile manufacturer and the downstream retailer in the middle of the industrial chain.In order to improve the efficiency of new energy vehicle power battery recycling,two cooperative recycling contract models are designed.By comparing and analyzing the battery recycling efficiency in the case of independent recycling and cooperative recycling,it is found that the two cooperative recycling contract strategies can effectively improve the battery recycling efficiency,is a better choice.When the manufacturer’s recovery cost coefficient is large and the retailer’s recovery cost coefficient is small,the recovery cost allocation contract is better;when the manufacturer’s recovery cost coefficient is small and the retailer’s recovery cost coefficient is large,the recovery responsibility allocation contract is better.Finally,it summarizes the research conclusions of this paper,puts forward suggestions for the development of my country’s new energy automobile industry chain,and summarizes the research deficiencies and the next research directions.
