Abstract: Current interactions of international institutions often take place in the context of institutional complexity, which refers to the governance structure of a large number of institutions and regimes in areas where some functions overlap. As an important platform for Chinas foreign political and economic cooperation, the “docking” between the “Belt and Road Initiative” and different institutions is a brand new way of interactions between international institutions. The “docking” of the international institutions is the integration between the “source institution” and the “target system”, aiming to generate “synergistic effects” between institutions. Based on institutional complexity, by constructing a theoretical framework to explain the differences in institutional “docking”, this paper theorizes that the “docking” of international institutions can be approached as “institutional embedding”, “institutional nesting” and “institutional generating”, and then verifies the explanatory effectiveness of the theoretical framework through cases of the docking of the “Belt and Road Initiative” with ASEAN and the United Nations and the creation of the AIIB.

Key words: the “Belt and Road Initiative”, docking of international institutions, institutional complexity, synergistic effects

摘要： 当前的国际制度互动往往发生于制度复杂性的环境之中，制度复杂性是指数量众多的制度在部分功能重叠领域的治理结构特征。作为中国对外政治经济合作的重要平台，“一带一路”与不同制度之间的“对接”是一种全新的国际制度互动方式。国际制度“对接”是“源制度”与“目标制度”之间的融合，旨在产生制度间的“协同效应”。在制度复杂性的基础上，通过构建一个解释制度“对接”差异化的理论框架，本文将国际制度“对接”理论化为“制度嵌入”“制度嵌套”和“制度生成”三种模式，进而通过“一带一路”与东盟、联合国的对接和亚投行的创设作为典型案例验证了该理论框架的解释效力。
