Based on the regional society system of ancient China,this paper discusses international administrative tools including countries,nations and people,and makes comparison of the economic capital,administrative organization and institutional norm of Europe,America and Asia. Through research,this paper concludes that the regional theory of China has both historic and practical significance.展开更多
