法系概念在比较法研究中有着极其重要的作用。法系将世界上不同国家的法律分为若干个种类,这在一定程度上研究降低了法学研究的难度。但法系分类标准过于多样性、宏观性,难以应对法律的全球化,容易忽视异文化法,难以确定比较法研究之范围。 The concept of law has an extremely important role in the study of comparative law. The law divides the laws of different countries in the world into several categories, which, to a certain extent, reduces the difficulty of legal research. However, the classification standard of legal system is too diverse and macroscopic, it is difficult to cope with the globalization of law, it is easy to ignore the different culture law and it is difficult to determine the scope of the comparative law study.
