In the past there decade, average economic growth rate gor emerging markets have been fairly above that of world average and debt of emerging markets are lower than that of advances economic. Thus, this paper attempts to discuss the evolution of external debt to DGP ratio in emerging economics and how it may have impacted on economic growth. Althouht the relationship between external debt level and economic growth is unclear, some studies have suggested that on average, high levels of external debt to GDP ratio is associated with slow economic growth (Hendon et all, 2013). Our anaysis is based on data from six emerging economies that are Brazil, India, Indonesia, Mexico, Nigeria and Turkey from 1972 to 2012.
