本文首次提出全新的管理概念——管要讲理(Managing According to Reason,简称MR)。管是指领导、计划、组织和控制,理是指被管客观事物的发展规律。管理新概念是管和理两大要素的集成。新的管理(MR)科学研究对象是管和理之间的矛盾关系...本文首次提出全新的管理概念——管要讲理(Managing According to Reason,简称MR)。管是指领导、计划、组织和控制,理是指被管客观事物的发展规律。管理新概念是管和理两大要素的集成。新的管理(MR)科学研究对象是管和理之间的矛盾关系及其发展变化的客观规律。新的管理(MR)科学是传统的管理学和哲学、自然科学、工程技术科学和人文社会科学的大集成。笔者认为,管要依靠权力,理要依靠科学,新的管理(MR)是权力和科学两大要素的集成,权力是管理(MR)的保证,科学是管理(MR)的根据,两者不能缺一,21世纪是新的管理(MR)世纪。展开更多
