瞿同祖先生在《中国法律和中国社会》中提倡要从事活动的、功能的法学研究:“仅仅研究条文是不够的,我们也应注意法律的实效问题。条文的规定是一回事,法律的实施又是一回事。某一法律不一定能执行,成为具文。社会现实与法律条文之间,往往存在着一定的差距。——我们应该知道法律在社会上的实施情况,是否有效,推行的程度如何,对人民的生活有什么影响等。”① In the Chinese law and Chinese society, Qu Tongzu advocated functional and legal studies to carry out activities: “It is not enough to study only the provisions, and we should also pay attention to the actual effectiveness of the law. The provisions of the articles are one thing, and the laws The same is true of the implementation of a law may not be able to enforce, become an article between the social reality and the legal provisions, there are often some gaps.- We should know the law in the community to implement the situation is effective, What is the extent of its implementation and what effect it has on people’s lives. ”
