摘　　要：为了研究京津冀城市群科技金融效率的时空演变特征,本文基于京津冀城市群2012—2023年面板数据,运用方向性超效率SBM模型和Malmquist指数、全局莫兰指数、标准差椭圆和空间马尔可夫链等方法分析京津冀城市圈科技金融效率时空演变和空间格局特征。实证结果显示:京津冀城市群总体科技金融效率呈现“W底”型变化,整体上呈上升趋势;京津冀城市内部科技金融效率差距较大,不同城市科技金融效率提升路径存在差异;京津冀城市群总体科技金融效率存在一定的空间协同影响,但大体格局未变;空间因素会影响科技金融效率,城市科技金融效率受原有发展水平影响较大,近邻效应会影响城市间的科技金融效率,邻域类型不同且转移概率不同。本文从效率分解和空间角度为提升京津冀科技金融效率提供理论依据,对推进京津冀科技金融协同发展具有重要意义。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.
