【摘要】 西部陆海新通道是中国西部地区对外开放的重要基础设施和新动力，在与东盟贸易互联互通中起着重要的桥梁和纽带作用。文章利用2015—2024年西部陆海新通道沿线地区对东盟进出口贸易数据，基于海关进出口商品（HS）2位数编码，从省份与国别“空间结构”和“商品结构”两个维度切入，分整体和省份两个层面对地区贸易格局进行测度。研究发现：首先，西部陆海新通道沿线地区较东部地区对东盟贸易比重低，经济发展水平及市场可达性等因素明显制约沿线地区与东盟的贸易；其次，沿线地区对东盟贸易格局空间差异逐渐缩小，呈明显“前沿—腹地—后方”格局，西部陆海新通道的建设使得后方省份在全国对东盟贸易中的优势显现，地位进一步提高；再次，越南是沿线地区的最大贸易伙伴，沿线地区的主要贸易伙伴各具特色，与东盟各国的贸易依存度各不相同；最后，沿线地区对东盟出口和进口的主要产品为机器电气设备，形成结构相近的三大出口组团和两大进口组团。更多还原

【Abstract】 The New Western Land-sea Corridor is a vital infrastructure and driving force for the opening up of China’s western regions, playing an important bridging and linking role in trade connectivity with ASEAN. Utilizing import and export trade data from 2015 to 2024 related to the provinces along the New Western Land-sea Corridor and ASEAN, this study employs 2-digit Harmonized System(HS) codes for customs import and export goods to analyze trade patterns from two dimensions:“spatial structure”and“Commodity Structure”at both the overall and provincial levels. The research findings are as follows: first, the regions along the New Western Land-sea Corridor exhibit a lower trade share with ASEAN compared to eastern regions, with factors such as economic development levels, geographical proximity, and market accessibility significantly constraining trade between these regions and ASEAN. Second, the spatial differences in trade patterns with ASEAN among the corridor regions are gradually narrowing, revealing a distinct“frontier-hinterland-rear”structure, with the rear provinces showing increasing advantages in national trade with ASEAN, indicating the initial effectiveness of the corridor’s construction. The effectiveness of the New Western Land-sea Corridor’s construction is beginning to manifest. Furthermore, Vietnam is the largest trading partner for the corridor regions, with each province having unique main trading partners and varying degrees of trade dependence on different ASEAN countries. Finally, the primary products exported to and imported from ASEAN by these regions are machinery and electrical equipment, demonstrating two major export clusters and three major import clusters with similar structures.更多还原
