西部大开发是中华民族改造自然、改造社会和改造人类自身的伟大实践。在西部大开发中 ,要坚持实事求是的客观性、实践性和能动性原则。检验西部大开发得失成败的根本标准是看实践的结果是否实现了“三个有利于” ,同时要注意实践结果的时效和转化等问题。 The great development of the western region is a great practice of the Chinese nation to transform nature, transform society and transform itself. In the large-scale development of the western region, we must uphold the objective, practical and initiative principle of seeking truth from facts. The fundamental criterion for testing the successes and failures of the development of the western region is whether the results of the practice have achieved “three benefits,” and at the same time pay attention to such issues as the limitation and conversion of the results of the practice.
