French legal sociology has been developed greatly after World War II, and plays an important role in the academic world with its distinctive features. Comparing to the Law and Society movement in the US, its theoretical paradigms and methodologies are more complex and more diverse. On the other hand, it also shows some certain assimilation tendencies. Especially, more and more researches pay attention to the relations between law and politics. On the basis of analysis on these characteristics, this article argues that, as an external perspective of law, the development of legal sociology is highly contextualist; its distance to law often depends on the perfection degree of legal system and the closure degree of legal studies in one country of specific period. Compared with the American tradition, French legal sociology is closer to and more suitable for the Chinese circumstance. Therefore, the study on French legal sociology can be a beneficial reference to the hot academic topics in recent years-the paradigm disputes of legal studies, as well as the disciplinary orientation of legal sociology in China.
