Abstract: If the country which has reached middleincome stage cannot achieve highincome stage through growth acceleration，it will fall into the middleincome trap.Based on three constrained conditions for economic growth slowdown and growth acceleration，we calculate Chinese data from 1960 to 2012 and find the timing points when the economy growth slows down and accelerates Then we use the Probit model to empirically study the sources which hinder China s economic growth acceleration from three aspects, which are structural factors, social and environmental factors and official corruption factors.In the last part, this paper puts forward the main results and related policy suggestions.

Key words: middle income trap , economic growth acceleration , Probit model
