作为一项新事物，“一带一路”既不同于现有的区域合作机制，也不同于现有的多边合作机制。本书试图运用经济学的方法对“一带一路”最基本的问题（是什么、做什么、如何做）进行系统的理论分析。这种分析至少需要满足三项基本原则：理论上的自洽，实践上的可行与认知上的国内外统一。以此为前提，本书系统阐述了“一带一路”的发展导向，并对其做出了一个学理化的定义，即以发展为导向的新型区域经济合作机制。这一定义为进一步研究其治理结构奠定了基础。“一带一路”的治理结构具有动态特征：尽管其起步阶段具有区域主义属性，但其开放性决定了最终目标是多边主义。针对学术界在“一带一路”目标研究中的“泛化”现象，本书提出了确定“一带一路”目标的标准，并对其目标的可行性进行了探讨，其中重点探讨了秉行正确义利观与“经济外交顶层设计”的关系。正确义利观不仅为“一带一路”的成功与否提供了衡量标准，而且也是中国特色经济外交的标志。经过第一阶段的成功实践，“一带一路”建设正在步人高质量发展阶段。本书以可持续 性作为高质量发展的切人点，提出实现可持续性的出路在于机制化。这种机制化并非是对现有区域经济一体化机制化模式的简单复制，而是要在共商、渐进性与义利观原则的指导下探索出一条新型发展道路。

As a new thing, the Belt and Road Initiative is different from both existing regional and multilateral cooperation mechanisms. This book attempts to use the methods of economics to provide a systematic theoretical analysis of the most basic problems of the "Belt and Road" (what is, what to do, and how to do it). This analysis needs to meet at least three basic principles: theoretical self-consistency, practical feasibility and cognitive unity at home and abroad. Based on this premise, this book systematically expounds the development orientation of the "Belt and Road" and makes a theoretical definition of it, that is, a new development-oriented regional economic cooperation mechanism. This definition lays the foundation for further study of its governance structure. The governance structure of the BRI is dynamic: despite its regionalist nature in its initial stages, its openness dictates that the ultimate goal is multilateralism. In view of the phenomenon of "generalization" in the academic research on the goals of the "Belt and Road", this book puts forward the criteria for determining the goals of the "Belt and Road" and discusses the feasibility of their goals, focusing on the relationship between upholding the correct concept of righteousness and benefit and the "top-level design of economic diplomacy". The correct concept of righteousness and benefit not only provides a measure of the success of the "Belt and Road", but also a symbol of economic diplomacy with Chinese characteristics. After the successful practice of the first stage, the "Belt and Road" construction is entering the stage of high-quality development. This book is known for sustainability As the cutting point of high-quality development, it is proposed that the way to achieve sustainability lies in institutionalization. This kind of institutionalization is not a simple copy of the existing regional economic integration institutionalization model, but a new development path should be explored under the guidance of the principles of consultation, gradualism and righteousness.（AI翻译）
