数字经济与新能源汽车产业的耦合协调及其影响因素OA

Based on the data from 2013-2023,a comprehensive evaluation index system for the digital economy and the new energy vehicle industry was constructed.Quantitative research was conducted us-ing the coupling coordination degree model and the obstacle degree model,and the evolution process of the coupling coordination degree was visually analyzed through a kernel density plot.The research find-ings are as follows:The development level of the digital economy and the new energy vehicle industry shows an upward growth trend,but the development of the new energy vehicle industry lags behind.As the collaborative development level continuously improves,the system coupling relationship is gradual-ly shifting from the initial mutual restraint to the stage of coordinated interaction.The main obstacle fac-tors to the coupled and coordinated development include the total volume of telecommunications servic-es,the number of websites per 100 enterprises,and the number of patent applications in high-tech in-dustries.Among them,the digital economy system has more obstacle factors,and its hindrance is great-er than that of the new energy vehicle industry system.
