摘　　要：在百年变局之中,为适应构建以国内大循环为主体的国内国际双循环新发展格局的需要,国务院提出了促进内外贸一体化发展的总体要求。本研究对经典的地理探测器原理进行了改进。选取长三角地区2007—2021年的内外贸易经济数据为样本,开展实证探究,揭示了内外贸易之间相互作用的内在机理。利用空间自相关模型分析内外贸发展水平的空间分布特征,通过测算耦合度分析内外贸一体化程度,利用地理探测器原理和回归分析模型探究长三角地区内外贸易相互作用机制。研究发现:1)长三角地区的内外贸易经济发展,在时间上,呈现不断上升的趋势;在空间上,呈现“一核多中心”的发展格局。2)长三角地区内外贸经济总体表现为显著的集聚发展态势。3)长三角地区内贸与外贸二者之间相互联系和相互影响,外贸水平每增加1个百分点可导致内贸水平增加1.0049个百分点。In order to meet the needs of building a new development pattern of domestic and international double circulation with domestic systemic circulation as the main body,the State Council has put forward the overall requirements for promoting the integrated development of domestic and foreign trade in the course of a century of changes.In the study,improvement ideas were proposed for the classic principles of geographic detectors,and improvement results were proposed,along with a proof process.Empirical research is conducted using domestic and foreign trade and economic data from the Yangtze River Delta region from 2007 to 2021 as a sample.Through empirical analysis,the internal mechanism of the interaction between domestic and foreign trade has been revealed.Using spatial autocorrelation models to analyze the spatial distribution characteristics of domestic and foreign trade development levels,analyzing the degree of integration of domestic and foreign trade by calculating the coupling coordination degree,and exploring the interaction mechanism of domestic and foreign trade in the Yangtze River Delta region using geographic detector principles and regression analysis models.The study found that:1)the economic development of domestic and foreign trade in the Yangtze River Delta region shows a continuous upward trend over time;in terms of space,it presents a development pattern of“one core and multiple centers”.2)The overall foreign trade economy in the Yangtze River Delta region shows a significant agglomeration development trend.3)There is a mutual connection and interaction between domestic and foreign trade in the Yangtze River Delta region.Every 1 percentage point increase in foreign trade level will lead to an increase of 1.0049 percentage points in domestic trade level.
