| The contradiction between the fast-growing economy and the ecological environment has intensified.In order to reduce the environmental pollution caused by travel modes,people have gradually turned their attention to new energy,making new energy a hot topic in the current society.In order to adapt to the market demand,We have to turn our attention to the development and utilization of new energy vehicles.Since the emergence of new energy vehicles in the 1990s,after more than 20 years of precipitation,the proportion of new energy vehicles in the automobile market is gradually increasing.In order to further expand the share of new energy enterprises in the domestic automobile market,the relevant departments of our government have promulgated a series of preferential policies on new energy vehicles in 2009.Especially at the New Energy Vehicle Conference in 2022,General Secretary Xi Jinping pointed out that it is necessary to deepen the exchanges and cooperation of new energy vehicles,give full play to the advantages of scientific and technological innovation achievements in social development,and create a better life for mankind.The research results of many experts and scholars show that among the various factors that directly affect the fluctuation of stock prices,stock prices are more restricted by "policy" factors.Therefore,it is particularly important to further study the relationship between stock price fluctuations and fiscal and tax policies.In the process of research,this paper takes the content of the policy as the basis,analyzes whether the promulgation of the policy has an impact on the stock price of the new energy vehicle company with the aid of the event research method,and at the same time summarizes the company’s financial indicators and stock market transaction data.Analyze whether the policy differs from company nature,geography,etc.,to further improve the credibility of existing results and provide stakeholders with reasonable opinions. |
