| With the rapid development of the economy and the continuous progress of the society,the concept that green mountains and green waters are the mountains of gold and silver has been deeply rooted in the hearts of people,and the country is attaching more and more importance to the development of low-carbon economy.New energy vehicles will reduce carbon dioxide emissions,help save energy and reduce emissions to protect the environment,and become the direction of the future sustainable development of China’s automobile industry.Due to the mutual cooperation of policy guidance,enterprise’s own innovation and market cooperation,China’s new energy automobile industry has maintained a very high growth rate for many years,and has been favored by investors everywhere.If investors want to use limited funds to effectively avoid risks and get the maximum investment income,they need to choose the most valuable investment objects to invest.Through the review of domestic and foreign research results,the investment value of enterprises is studied from two aspects in the research process,which makes the measurement of enterprise investment value more accurate,and also provides a reference for the study of other industries.Investment value analysis results not only can help investors to invest scientifically,effectively avoid risk,also can help shareholders to make the right investment decisions,and by the external environment and internal conditions of listed companies,corporate decision makers can adjust the development plan,according to the comprehensive analysis and timely reflection and the quantitative effective measures according to actual situation,is advantageous to the steady and healthy development of the enterprises and the securities market.Based on the theory and industry analysis,the choice of scientific financial indicators of new energy vehicles listed companies investing value evaluation index system,using SPSS25 through factor analysis to study the 2016-2018,180 new energy vehicles has investment value of listed companies in enterprises,and by using the BP neural network toolbox of MATLAB software,the construction of new energy vehicles listed companies investing value evaluation model.Basic clues of thesis are as follows: first,by reviewing domestic and foreign related to new energy automotive industry and investment value of literature,according to our country the development of the industry background,reality and related theoretical basisand analysis method,constructs the effective scientific investment value evaluation index system of listed company,and according to the opinions of the experts using analytic hierarchy process(ahp)to determine the weights of indicators and secondary indicators.Secondly,from the selected samples,financial indicators,dimension through the factor analysis method,makes the extracted four financial indicators can explain the selection of11 index contains the main information,.Through the comprehensive score evaluation model of new energy vehicles listed companies from 2016 to 2018 of intrinsic investment value,analyze the investment value and stability of the enterprise,and investment value will be 2018 rankings and price-to-book rankings comparative analysis of the current situation of development of new energy vehicles listed companies,analyze the market overvalued or undervalued by the market is worth investing have great development potential of the enterprise,For industry investors reference.Finally,using BP neural network to build the new energy vehicles listed company investment value evaluation model,using the 180 listed companies for three consecutive years of financial data and analytic hierarchy process(ahp)to obtain weights to get the output target,identify 11 input layer,one hidden layer and output layer 1 of the evaluation model,and 180 new energy vehicles in China listed companies to empirical research,future investors can take advantage of this model is to choose the same financial indicators,to want to invest in enterprises according to the error rate of investment value evaluation.Through theoretical research and empirical analysis,it can help investors avoid investment risks,choose listed enterprises of new energy vehicles with investment value to invest,and increase the success rate of investment.The decision-maker of the enterprise can also use and reference to help the decision making and the development of the company.Government departments can also consider the development of the industry and formulate corresponding policies according to the analysis.The research on the investment value of listed enterprises of new energy vehicles is of positive significance to the development of China’s new energy vehicle industry,the stability of the market and the establishment of a reasonable market structure. |
