Abstract: Based on classical economic growth theories, combined with the characteristics of middleincome countries, the following theoretical assumptions were proposed in this paper: in middleincome countries, inflation caused by the loss of family benefits would seriously affect the macroeconomic development and thus promoted the countries falling into “middle income trap” This paper used FGLS, difference GMM, and system GMM methods to analyze the panel data of four groups of typical “middle income trap” suffered countries The results showed that: after controlling the factors such as infrastructure, debt level, technological innovation and savings rates, inflation had a significant negative impact on per capita GDP growth at all four groups of countries Even for the East Asian group whose average annual inflation rate was only 514 %, the impact of inflation on per capita GDP growth also reached 123～221 percentage points, and the gravity of impact reached 27%～48% Therefore, Chinese economy would develop sustainably and healthily by strengthening the control of inflation
