European Economic Integration and Development of European Union Economic Constitution --From the Perspective of the Institutional and Evolutionary Economics

摘要

Institutional and evolutionary economics believes that, the successes of economic organizations are owing to the allocation efficiency brought about by the enlargement of markets, and the "adaptive efficiency"comes Produced by institutional development. European economic integration could be considered as a process of complex evolution, in which actors with different interest preferences choose and implement different integration strategies, and the interactions among them result in the emergence of the institutions. Economic constitution can be understood as the totality of laws and institutional arrangements regulating the economic activities. As an entity "sui generis", EU has already had capabilities to make an economic constitution to some extent. However, such a "constitution" could not substitute the constitutions of EU Member States entirely, and it has to share the competences with the Member States on the principle of subsidiarity.
