Based on this, this paper firstly constructed a digital economy development evaluation index system consisting of five potential factors, including digital economy environment, digital industry development, digital infrastructure, industrial digital development and digital innovation level. Then, considering the information quantity, volatility and relevance of each evaluation index, this paper chose the combination of entropy and CRITIC method to quantify the five potential factors and calculated the digital economy development level based on TOPSIS method. Then, k-means clustering and greyscale models were used to analyse the spatial and temporal clustering and forecast the development level of the digital economy in each region. The empirical results show that the development trend of digital economy in cities along China's \"One Belt, One Road\" has been steadily increasing, but the balance of the digital economy development level of each city still needs to be improved. The growth rate of the digital economy is more pronounced in coastal cities than inland cities. Finally, suggestions are made to improve the quality construction of \"One Belt, One Road\" and the balance of digital economy development in China.","PeriodicalId":219637,"journal":{"name":"Journal of Computational and Financial Econometrics","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129236836","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study on the measurement of the new kinetic energy of economic development in Guangdong Province is helpful to the high-quality development of Guangdong's economy. Taking Guangdong Province as an example, 13 indicators were selected from four dimensions of openness level, development effectiveness, scientific and technological innovation, and economic vitality to construct a measurement and evaluation system for the new kinetic energy of economic development in Guangdong Province. Three common factors, namely external and science and technology, innovation and development, and economic vitality, were obtained by using factor analysis method. The total score of the new kinetic energy of economic development in Guangdong Province was calculated and empirically analyzed. The model has a good effect and the empirical results show that the growth rate of the new growth drivers of Guangdong's economy is obvious, but it is still at a low level of development, and there is a large room for improvement. Finally, three suggestions are put forward to stimulate innovation, enhance the openness level and optimize the industrial structure.","PeriodicalId":219637,"journal":{"name":"Journal of Computational and Financial Econometrics","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134200486","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
