改革开放三十多年来,虽然中国体育尤其是竞技体育取得了举世瞩目的成就,但是发展中仍存在一些不足。要实现中国体育的可持续发展,就必须转变发展观念和发展方式,并建立现代化的体育治理模式,而法治则是中国体育现代化的必由之路。尽管从1995年《中华人民共和国体育法》发布实施以来,中国的体育立法取得了很大的进展,但是在一些领域仍然滞后,特别是面对体育的社会化、产业化带来的新问题反应比较慢。因此,社会管理和市场管理是加强体育立法的重要方向。管理机构应该围绕权利和秩序这两个着眼点,完善体育立法,健全救济机制。体育仲裁问题成为当前国内体育法研究和体育制度建设中的一个热门话题,已有多名来自中国的仲裁员参与了国际体育仲裁庭的仲裁事务。国际体育仲裁制度的建立和发展,是对国际体育秩序的完善,同时它对各国国内体育救济机制的完善也具有指导和推动作用。的翻译是:
