世界经济史的主题,是按时序描述和阐释人类世界的经济发展和制度演进,包括所有国家和民族经济增长的实绩、经济交往、制度创新,以及各民族经济在历史上的竞争、冲突、融合与发展。因而,世界经济史是历时性与共时性的统一,是多线式发展与单线性发展的统一。我们必须运用历史与逻辑一致的方法,研究世界经济史的时间结构和空间结构,研究世界经济史的演进规律。 The theme of the world economic history is to describe and explain the economic development and system evolution of the human world in a time-series manner, including the achievements of economic growth in all countries and nations, economic exchanges, institutional innovations, and historic competitions, conflicts and mergers in the national economies And development. Therefore, the history of world economy is the unity of diachronic and synchronicity, and the unification of multi-line development and single-line development. We must use historical and logical methods to study the time structure and spatial structure of the world economic history and study the evolution law of the world economic history.
