Abstract

In this research, the growth collapse experienced by 119 economic entities in the world from 1950 to 2010 is quantitatively analyzed. And the objective existence of the middle-income trap is proved from a statistical perspective. On this basis, the existing identification methods of middle-income trap are evaluated and revised. In addition, the late-developing economic entities that have been caught in the middle-income trap in history and the duration of the trap are identified, thus providing several policy references and guidance to step-over the middle-income trap.
