民族区域自治是我国解决民族问题的基本国策 ,新中国五十多年的实践证明 ,它是适合中国国情的成功政策。笔者认为 ,它的成功实践与其自身特点密不可分。这些特点包括 :国家利益与民族利益的统一 ;目的与手段的统一 ;政治与经济的统一 ;原则性与灵活性的统一 ;广泛性与独享性的统一 ;法律与政策的统一。它们同时也是我国民族区域自治的优点 ,它们是六对矛盾的统一体 ,从而实现了对民族区域自治的利益、手段、权利、范围、执行等各方面的因素加以限制和保障 ,使之各方面因素形成相互制约 ,相互补充的统一的有机体。既保障了少数民族的合理的平等权利 ,又防止了各种民族主义的因素 ;既保证了国家的统一稳定 ,又促进了民族自治地方的充分发展 Regional ethnic autonomy is the basic national policy of our country to solve ethnic problems. The practice in more than 50 years in New China proves that it is a successful policy suited to China’s national conditions. The author believes that its successful practice and its own characteristics are inseparable. These characteristics include: the unification of national interests and national interests; the unity of purpose and means; the unification of politics and economy; the unification of principle and flexibility; the unification of universality and exclusiveness; and the unification of law and policy. They are also the merit of the regional autonomy of our country. They are the unity of six pairs of contradictions, so as to limit and guarantee the interests, means, rights, scope and implementation of the regional autonomy of ethnic minorities so that all aspects Factors form a unified body of mutual restraint and complementarity. Which not only guaranteed the reasonable equal rights of ethnic minorities but also prevented the various elements of nationalism. It not only guaranteed the unity and stability of the country but also promoted the full development of ethnic autonomous areas
