Abstract: 【Purpose/significance】Lotka's law and scientific productivity are important tools to analyze and understand the discipline development law, and help to re-examine the development status and mutual relationship of Humanities and Social Sciences in China. 【Method/process】Using the academic papers of Duplicate Newspaper and Periodical Materials as the research basic data, this paper classifies and describes the scientific productivity of Chinese Humanities and Social Sciences as a whole and each first-level disci⁃ pline according to Lotka's law.【Result/conclusion】The results show that the overall scientific productivity of Humanities and Social Sciences has a downward trend year by year, and the number of low yield authors has shrunk significantly; There are obvious differenc⁃ es in science productivity among the first-level disciplines, and some applied or popular disciplines still have good development poten⁃ tial; After 2016, a series of policies to encourage the development of philosophy and social sciences with Chinese characteristics have played a significant role in promoting the discipline development.【Innovation/limitation】For the first time, the integrity and accuracy of the data of the second literature of Chinese Humanities and Social Sciences and the overall research of its branches are well guaran⁃ teed, and the development relationship among several first-class disciplines of Chinese Humanities and Social Sciences is deeply ana⁃ lyzed.
