我国十大城市群对外贸易空间效应研究——基于区域性国际贸易中心的视角

Research on Spatial Effect of Foreign Trade of Ten Urban Agglomerations—— Based on Regional International Trade Center

经济全球化背景下,城市群作为全新区域单元参与国际贸易,综合反映国家外贸水平;区域性国际贸易中心又是城市群外贸水平的集中体现。本文以我国十大城市群为研究样本,观察各城市群对外贸易空间效应。结合贸易引力模型建立空间权值矩阵,运用ARCGIS和GEODA软件检验,发现东部沿海地区城市群呈现较好集聚和辐射效应,中西部内陆地区效应并不明显,并明确在"一带一路"战略背景下我国对外贸易的整体布局应实施差异化发展策略。

During economic globalization, the urban agglomerations participating in the international trade, reflects the overall level of national foreign trade. Regional international trade center is the concentrated reflection. This paper takes top ten urban agglomerations as research samples, observing the spatial effect of foreign trade with a spatial weight matrix, correlation analysis using ARCGIS and GEODA software , to find that the eastern coastal area has a good concentration and radiation effect, while midwest hinterland effect is not obvious, then corresponding advice is given.
