2 0世纪上半叶 ,我国法学家提出了义务本位、权利本位、社会本位、义务先在、权利义务并重乃至权利权力中心等多种观念。这个时期的法本位研究是富有开创性的 ,取得了一些值得重视的认识成果 ,但同时也显现了基础性分析框架不合理、对所涉及的法现象本身缺乏深入的理解等缺失。这些成功和失误都对 2 0世纪末期的法本位研究产生了深刻的影响。 In the first half of the 20th century, our jurists put forward many concepts such as obligation-based, right-based, social-based, obligations first, equal emphasis on rights and obligations, and even rights and power centers. The research on legal law in this period is groundbreaking and has achieved some worthy cognition results. However, it also shows the lack of fundamental analysis framework and lack of in-depth understanding of the law phenomenon involved. All these successes and mistakes have had a profound impact on the legal-based research in the late 20th century.
