Spatio-Temporal Evolution Pattern of Technological and Financial Efficiency in the Beijing-Tianjin-Hebei Urban Agglomeration
In order to study the spatio-temporal evolution characteristics of the efficiency of science and tech-nology finance in the Beijing-Tianjin-Hebei urban agglomeration,based on the panel data of the Beijing-Tian-jin-Hebei urban agglomeration from 2012 to 2023,this paper analyzes the spatio-temporal evolution and spatial pattern of the sci-tech financial efficiency of the Beijing-Tianjin-Hebei metropolitan area by using directional super-efficiency SBM model,Malmquist index,global Molan index,standard deviation ellipse and spatial Markov chain. The empirical results show that the overall sci-tech financial efficiency of the Beijing-Tianjin-Hebei urban agglomeration shows a "W" shape change,and the overall trend is increasing. There is a large gap in the efficiency of sci-tech finance within Beijing,Tianjin and Hebei,and there are differences in the im-provement paths of sci-tech finance efficiency among different cities. The overall sci-tech financial efficiency in Beijing-Tianjin-Hebei urban agglomeration has a certain spatial impact,but the general pattern remains un-changed. Spatial factors will affect the efficiency of science and technology finance,and the efficiency of sci-ence and technology finance in cities is greatly affected by the original development level. This paper provides a theoretical basis for improving the efficiency of science and technology finance in Beijing-Tianjin-Hebei from the perspective of efficiency decomposition and space,which is of great significance for promoting the coordi-nated development of science and technology finance in Beijing-Tianjin-Hebei.
