Research On The Impact Of Digital Economy On High-quality Economic Development In The Yellow River Basin

As an important economic zone and ecological barrier,the Yellow River Basin plays an important role in the national economic and social development pattern.So how to achieve high-quality economic development in the Yellow River Basin has become an important issue of concern to all sectors of society.As a newly emerging economic form in recent years,the digital economy has improved the level of digitalization and intelligence of traditional industries through technological empowerment,and has affected various aspects of the national economy and society.It has opened up a new path for economic development,effectively improving the efficiency of resource element flow in various regions.In this context,this paper discusses the theoretical mechanism of digital economy promoting high-quality economic development in the Yellow River Basin,measures the development level of digital economy and high-quality economic development in the Yellow River Basin,and empirically analyzes the relationship between the two.This paper firstly reviews relevant literature research on the digital economy and high-quality economic development at home and abroad,clarifies the research content of this paper,and defines the connotation of the digital economy and high-quality economic development on this basis.Secondly,it explores the mechanism by which the development of digital economy affects the high-quality development of the Yellow River Basin economy,and proposes research hypotheses.Thirdly,this paper systematically and objectively constructs a comprehensive evaluation index system for the digital economy and high-quality economic development in the Yellow River basin.Based on panel data from 32prefecture-level cities in the Yellow River basin from 2011 to 2020,it measures the development level of the digital economy and the comprehensive index for high-quality economic development in the Yellow River basin,and analyzes the current situation and differences of the digital economy and high-quality economic development in various prefecture-level cities in the Yellow River basin.Finally,based on the indicator measurement results and panel data,this paper constructs a model and conducts empirical analysis.By constructing a panel dual fixed model,it examines the promotion effect of digital economy on the high-quality development of the Yellow River basin economy.It uses a panel threshold model to explore the non-linear characteristics of digital economy affecting the high-quality development of the Yellow River basin economy,and analyzes the heterogeneity of digital economy affecting the economy of the Yellow River basin through panel quantile models,and finally explores the spatial spillover effects of digital economy on high-quality economic development in the Yellow River basin through spatial econometric models.Finally,this paper can draw the following conclusions:Firstly,in recent years,the development level of the digital economy in the Yellow River Basin has generally remained consistent with the high-quality development level of the economy,showing a steady upward trend overall.The middle and lower reaches have benefited from the improvement of infrastructure construction and the rapid development of digital technology applications,while the development of the upper reaches has been relatively slow.Secondly,the digital economy can significantly drive the high-quality economic development of various cities in the Yellow River basin,and significantly promote the four dimensions of innovation,coordination,green,and openness in high-quality economic development.Among them,the digital economy has the most significant impact on innovation,but its impact on sharing is not significant.Thirdly,the digital economy has a significant nonlinear impact on the high-quality development of the Yellow River basin economy,that is,when the development of the digital economy reaches a certain level,its impact on the high-quality development of the Yellow River basin economy will significantly increase.Fourthly,there are regional and economic heterogeneity in the high-quality development of the Yellow River Basin economy due to the digital economy.Fifthly,the digital economy has a significant spatial inhibitory effect on the high-quality economic development of the Yellow River basin,which means that the development of the digital economy in this region will have a negative impact on the high-quality economic development of other regions in the Yellow River basin.
