摘　　要：伴随区域协调发展战略的深度实施,我国区域空间布局不断优化,西部地区有望成为对外开放的新窗口,探究西部地区双循环水平时空差异及其驱动因素具有重要意义。基于2012—2022年83个城市数据,构建西部地区双循环评价指标体系并测算西部地区双循环的整体性进展,运用核密度估计、Dagum基尼系数分解等方法剖析西部地区双循环水平的时空差异特征,采用地理探测器探究其驱动因素。研究发现:从时序演变看,西部地区双循环水平在样本研究期内呈现渐进式增长特征;从空间演变看,西部地区双循环水平总体差异逐渐下降,地区内差异成为西部地区总体差异的主要来源;从驱动因素看,西部地区双循环水平受多因素的共同驱动,人力资本是最主要的驱动因素。With the deepening of the coordinated regional development strategy and the continuous optimization of China’s regional spatial layout,the western region is expected to become a new window for opening up,and it is of great significance to explore the spatiotemporal differences and driving factors of the dual circulation development level in the western region.Based on the data of 83 cities from 2012 to 2022,this paper constructs an evaluation index system for the level of dual circulation in the western region and measure its overall progress.The kernel density estimation and Dagum Gini coefficient decomposition are used to analyze the spatiotemporal differences and the geographical detector is used to explore the driving factors.The results show that:from the perspective of time series evolution,the level of dual circulation in the western region showed a gradual increase during the sample study period.From the perspective of spatial evolution,the overall difference in the level of dual circulation in the western region gradually decreased,and the intra-regional difference became the main source of the overall difference in the western region.From the perspective of driving factors,the development of dual circulation in the western region is driven by multiple factors,among which human capital is the most important driving factor.
