社会心态是人类群体、民族、团体及个人受一定社会环境影响，在意识行为上的反映和表现　。其表现形式较政治、经济难以把握，也容易为人们忽略，实际上社会心态却对　历史进程起着重要的影响。北洋时期的社会心态主要有“接受”、“回归”和“再选择”三　种主流表现，这三种心态在北洋时期建立民国、复辟倒退和维护革命成果三大主题中，与政　治、经济、文化等因素一起构成推动历史运动的合力，共同影响着北洋历史的进程。这表明　北洋历史运动的发展不是简单地由政治和经济两项因素所决定，而是由更多的因素包括社会　心态在内共同作用的结果。 Social mentality is the reflection and performance of human groups, ethnic groups, groups and individuals under the influence of a certain social environment and their conscious behaviors. Its manifestations are more political and economic than control. It is also easy for people to ignore. In fact, the social mentality plays an important role in the historical process. In the Beiyang social mentality, there are mainly three main manifestations of “acceptance”, “return”, and “re-selection.” Of the three major themes of the founding of the Republic of China, restoration and retrogression of the Beiyang period and the maintenance of the revolutionary achievements, Culture and other factors together constitute the resultant force of promoting the historical movement and jointly influence the course of the history of the Northern Ocean. This shows that the development of the Northern Historical Movement was not simply determined by political and economic factors but by a combination of more factors, including the social mentality. 
