Evaluation Of The Development Level Of China’s New Energy Vehicle Enterprises And Analysis Of Influencing Factors

With the development of the automobile industry,while automobiles bring convenience to our lives,problems such as energy shortage and environmental pollution also follow.As a new form of vehicle system,new energy vehicles have the characteristics of environmental protection and low energy consumption.Vigorously promoting and using new energy vehicles can effectively alleviate the current energy crisis.my country began to promote new energy vehicles in 2008,and has achieved initial results,but the market share of new energy vehicles is still low at this stage,so it is necessary to conduct a reasonable analysis of my country’s new energy vehicle enterprises to explore the impact of my country’s new energy vehicles factors of business development.Therefore,from the perspective of enterprises,this paper evaluates the development level of six new energy vehicle enterprises in my country at this stage,and analyzes the factors affecting the development of my country’s new energy vehicle enterprises,in order to provide relevant suggestions for the sustainable development of my country’s new energy vehicle industry.First,this paper uses BP neural network to construct a development level evaluation model from four perspectives,and analyzes six new energy vehicle companies.Through empirical research,it is found that the comprehensive development level of the three established new energy vehicle enterprises is significantly higher than that of the three emerging new energy vehicle enterprises.Among the three established car companies,Tesla has developed faster and higher quality,while BYD and CATL have relatively stable development.Among the three emerging car companies,Xiaopeng Motors has a relatively balanced development,and indicators such as ideal car operating capabilities are at a high level.NIO’s profitability and ability to resist financial risks are weak.Secondly,this paper analyzes the influence of various factors on the development level of my country’s new energy vehicle enterprises.This paper conducts principal component analysis on each influencing factor,and extracts three principal component factors: external ecological factor,enterprise internal development factor,and oil price level factor.Then,VAR models were established for the three factors,and impulse response analysis and variance analysis were performed.Through analysis,it is found that among the external ecological factors,the number of public charging piles and national support policies have a greater impact on the development level,and the number of public charging piles will promote the long-term development of new energy vehicle companies.It has a strong promoting effect in the short term but is not conducive to long-term development.Among the internal development factors of the enterprise,the R&D investment and marketing investment of the enterprise have a good promoting effect on the development of the enterprise,and the R&D investment has a better promotion effect and a faster response speed than the marketing investment.The effect of the oil price level factor on the development level is very obvious,and there is a trend of continuous influence.Finally,according to the previous analysis of the influencing factors,five key influencing factors are extracted,and the gray BP neural network prediction model is used to predict the development level of my country’s new energy vehicle enterprises in the next three quarters.
