The construction of China’s self-independent knowledge system of legal science is to build a legal knowledge system that covers all disciplines of Chinese legal science and highlights Chinese academic autonomy, originality and practicality. This is the general requirement of China for the research of philosophy and social sciences, and it is also the responsibility and expectation of scholars in the current academic research. As an important part of the legal academic community, no matter the law column of comprehensive journals or professional legal journals, they should contribute to the construction of China’s self-independent knowledge system of legal science. It is the mission of academic journals to compile and publish original, independent and practical legal achievements. The importance of the topic of law paper is self-evident, under the trend and requirement of constructing China’s independent legal knowledge system. To determine the cutting-edge, original and breakthrough topic is the first step for an excellent law paper to write. In the new era, the research requirements of the topic selection of law papers should be changed from the original introduction, comprehensiveness and generality to the independent, original and realistic topic selection, to the prominent problem consciousness and clear research purpose. It not only requires that the research topic should constantly strengthen the issue orientation and form the issue consciousness, but also puts forward new requirements for the grasp of the direction and content of the research issues in the issue consciousness, which is the basic starting point of legal academic research, and an important standard for journals to judge the quality of legal papers. When editors set columns in the journal, they should try their best to guide the legal research achievements to flow into this goal and form research forces. The scientific research method gives legal research a new perspective and topic selection direction, and the pluralism of legal research method promotes the new change of topic selection of legal papers. And the appropriate title design will make the content of the topic of the law paper clear and accurate. When determining the title of an article, two kinds of titles need to be treated with caution: the homogenized title should be strictly selected; academic judgment is required for titles that are self-explanatory and overly decorative. Therefore, how to face the Chinese problem, refine the Chinese problem and solve the Chinese problem are new requirements of the times, and they are also important missions of the law circle and the periodical circle. This requires that the topic selection of legal papers should take these as research direction and basic requirements, and the research methods should be deeply developed. The legal academia and the periodical circle should practice this goal with a high sense of responsibility in academic research.
