| At present,the reduction of international market demand has made China’s export-oriented economic development model face severe challenges.Therefore,China has put forward the“One Belt,One Road”strategy,and the Central European train is an iconic development project.Since the opening of China-European trains,although it has made China’s trade with foreign countries more convenient,the China-European trains themselves still have many problems due to their development.The long-standing lines are repeated repeatedly,and the return of empty trains has also made the Central European trains.The cost of the operation increased.Therefore,whether the opening of the Central European train has a positive impact on the Chinese economy remains to be studied.Studying the influence of China-European competition on China’s economy has certain practical significance.Firstly,studying the impact of the opening of the China-European class under the "Belt and Road" strategy on China’s economy is closely related to the development of the times.Secondly,the impact of foreign trade on the economy has been It is an important research direction.Finally,China Europe and Europe are the key projects of China in recent years.The in-depth study of it will also help China’s next strategic development.However,the study found that the scale of China-European trains has grown rapidly,and the data of many new trains is difficult to collect.Therefore,this paper selects the economics of several provinces in the central and western regions of China that have opened earlier.The specific impact;secondly,because it is necessary to study the economic changes before and after the opening of the class and the comparison between the provinces opened and the provinces that have not been opened,the simple regression analysis can not separate some macro factors and can not remove the differences before the opening and opening of the provinces.The double difference model,the double scoring model can not only remove the influence of other factors besides the opening of the train,but also compensate for the problem that the "natural experiment" cannot randomly allocate the observation sample.The wind data database is mainly used to collect the data used in this paper.According to the time of opening the Central European train,the two groups are divided into four groups to establish a double difference model.The provinces with the opening of the Central European trains before and after the opening and other central and western regions without the opening of the Central European trains are compared.The regional economic changes,specifically analyze the impact of the opening of the China-European class on the economy.It is proved by evidence that the opening of the China-European class has indeed promoted the economy of the country.After that,the earliest “Xinxin Europe ” class was explored to explore the specific reasons for its GDP growth in Chongqing.In view of the conclusions obtained and the problems found in the research,this paper proposes: Encourage the opening of the Central European trains and the nodes in the Central European trains to assemble the goods in order to generate economies of scale and promote economic development,and put forward the line on the serious situation of the repetition of the routes in China and Europe.Optimization is carried out to improve the utilization rate of the line.Finally,it is proposed to expand the scope of services and improve the competitiveness of the trains in China and Europe.The innovation of this paper is that the research content is the current hot issue,and the time for the opening of the China-Europe class is short,and there are still few people studying.The research in this paper can enrich this.Secondly,the dual difference method is combined with the Chinese-European economy.In the study,it was proved that the China-Europe team did positively promote the Chinese economy. |
