The causes for the decline of ancient Greek Olym-pic Games include defects in the polis political system, instability of agricultural economy, and disappearance of competitive spirit. Problems occurred in the modern Olympic movement include over politicization of sport, two extremes in economic development, increased difference between the rich and the poor, and negligence of ethical standard and competitive spirit of athletes. The authors derived the following enlightenment from comparing the an-cient and modern Olympic movement: narrow economic difference; increase investment; perfect systems; strengthen policy execution; boost the return of humanistic spirit.
