Is a measure of the effectiveness of the international system, international system shape and influence the extent to which a measure of international behavior. From system to system function study of the effect of track, through the United Nations Security Council during the 2000-2005 analysis of issues dealt with, the use of set of assessment methods, study of the functioning of the UN Security Council, it can be concluded: the UN Security Council as a international system, its current functions of the play is complex, in conflict prevention and conflict resolution in the Council of the issues can not be fully functional, the system less effective, and in post-conflict peace-building and global issues on the Council's relative can play a role more fully. The effectiveness of international institutions is a scale to measure how much international institutions can shape and influence the international behavior. By following the research track from the functions to the effects of institutions, this paper does a research on almost all the issues discussed by UN Security Council, applying the assessment approach we design by ourselves, to examine the operation and functions of UN Security Council. We draw the conclusion that UN Security Council, as an international institution, plays complex roles; it can not play its roles in the issues of preventing and resolving conflicts, therefore its effectives in these issues is bad; but it is effective and can play relatively important roles in the issues of peace building after conflicts and in the global issues.

Post-Cold War international system is characterized by two prominent U.S. hegemony and a unipolar world dominated China's rapid development. China and the U.S. in the current international system there is both structurally strategic contradiction, but because of the limitations of U.S. hegemony and its process of rapid development in China in the domestic difficulties faced, particularly strong in China's foreign economic dependence , but also makes the structural contradiction between the two countries can not control will not evolve into large-scale conflict. As the Sino-US relations and cooperation between the co-existence of this contradiction the complex nature of bilateral relations in recent years, showing a very obvious, cyclical ups and downs of the prominent features. The near term, the two countries in their respective core fundamental conflict of interest does not exist; the long run, the two countries to avoid conflict, to strengthen cooperation in line with their national interests; the same time, international political changes in the nature of authority also will change the international system will inevitably lead to changes in the distribution of power among the major powers of the traditional understanding of conflict; In addition, diplomacy can play an important role in promoting peaceful means of their respective national interests between the two countries. The international system in the post-Cold War world is characterized by the unipolarity dominated by American hegemony and the rapid development of China. While structurally there is strategic contradiction between China and the United States in the international system, the interdependence between them also has increased continually. This characteristic has been marked by the ups and downs in their bilateral relations periodically. The author argues that there exists no critical conflicts of vital interests between the two states in the short term; in the long ran, it is strategically important and in their interests to avoid confrontation and strengthen cooperation; meanwhile, the changes of the nature of power will modify the traditional view of power in the sor1d polities; in addition, diplomacy can also play a significant role
