扩散—回波效应最初是由发展经济学家缪尔达尔提出,之后几十年学术界对这一对概念进行了多角度探索,从经济学领域到非经济学视角,从定性研究到定量分析,从实践经验总结到理论模型构建,使之成为经济学研究的一个重要议题。本文概述了缪尔达尔循环累积因果关系和扩散—回波效应的基本观点,探讨了这一理论研究的传承脉络、最新进展和模型化趋向,提出缪尔达尔转折点和空间成本这两个基本概念。
The diffusion-echo effect was first proposed by the development economist Myrdal. After decades, the academic community conducted a multi-angle exploration of this concept. From the economic field to the non-economic perspective, from qualitative research to quantitative analysis , From the summary of practical experience to the construction of theoretical model, making it an important topic in economic research. This paper summarizes the basic concepts of the cumulative and causal relationship and the diffusion-echo effect of the Myrrul cycle, explores the inheritance, the latest progress and the tendency of modeling of the theoretical study, and proposes the two basic concepts of the Myrdal turning point and the space cost .
