文章以39个“一带一路”共建国家金融服务业为研究对象，基于全球价值链视角，刻画共建国家金融服务业在全球价值链中的参与度、分工位置等特征，分析共建国家金融服务业的全球价值链合作形式、双边依存度等，采用QAP分析法准确测量关系数据之间的策动机制。研究发现：“一带一路”共建国家在全球价值链参与度与国际资源依存度方面存在较大差异；不同国家经济金融发展水平不同，金融服务业合作在空间距离的相关性上呈现离散化特征；SNA分析表明，在 DVA、RDV、FVA 网络中分别有不同轴心国，PDC网络去中心化并形成欧亚派系；空间位置、经济发展水平、金融开放程度、金融发展规模以及利率差异是影响共建国家金融服务业增加值贸易网络的主要因素。今后应优化“一带一路”共建国家金融服务业发展方式，调整国际资源依存结构，推进金融合作高效发展。

This paper takes the financial services industry of 39 countries participating in the Belt and Road Initiative as the research object. Based on the perspective of the global value chain, it depicts the participation degree and division of labor position of the financial services industry of the participating countries in the global value chain, analyzes the forms of global value chain cooperation and bilateral interdependence of the financial services industry of the participating countries, and uses the QAP analysis method to accurately measure the driving mechanism between the relationship data. The research finds that there are significant differences among the participating countries in terms of their participation in the global value chain and their dependence on international resources. The correlation of financial services cooperation among different countries with different economic and financial development levels gradually shows a random state in terms of economic distance. SNA analysis shows that there are different core countries in the DVA, RDV, and FVA networks, and the PDC network is decentralized and forms an Eurasian faction. Spatial location, economic development differences, financial openness differences, and financial scale differences are the main driving factors of the value-added trade network of the financial services industry of the participating countries. In the future, the development mode of the financial services industry of the countries participating in the Belt and Road Initiative should be optimized, the structure of international resource dependence should be adjusted, and efficient financial cooperation should be promoted.
