Adopting document and mathematical statics and so on as research methods, the 2012 Olym⁃pic Games as research platform, the paper conducts the research through analyzing the number of regional ad⁃vantageous projects and creating regional advantageous project group . The research has shown that the re⁃gional advantageous projects is dominant in Europe but worried in both Oceania and Africa, and has differenc⁃es between Asia and America. Therefore, it is suggested that regional advantageous projects should be distrib⁃uted hierarchically and the competition and confrontation of each project should be improved, based on the sustainable development of the Olympic Games, in order to solve the problem that each region takes on advan⁃tageous projects and the division of projects lacks confrontation.%采用文献资料、数理统计等研究方法，研究平台为2012年奥运会，以分析各地区优势项目数并创建各地区竞技体育比较优势项目群为核心展开研究。研究表明，欧洲地区优势项目占主导地位；亚洲和美洲优势项目存在差异性；大洋洲和非洲优势项目群令人担忧。建议各地区比较优势项目要分层布局；各地区包揽优势项目，项目分工缺泛对抗性，应基于奥运会的可持续发展提高各项目的竞技性和对抗性。
