The institutional changes of economic integration that include the reconstruction of international system and countries'economic integration which to meet the convergence of system reform. In the two system, the costs of system and ideology played an important role. Based on this theory, the article is to analyze 1990 - 2005 institutional Change of economic integration of East Asia.ASEAN has become the pioneer of East Asia regional economic integration after the cold world time. Basing on paying the cost and building the common sense, the building of regional institution and reformation of the convergence of countries made certain achievements.1997 East Asian broke out financial crisis, which was means that the potential of "East Asian Miracle" system has disappeared, East Asian countries faced with a new transition of system.
