[Purpose/significance] The preprint platform is an early publishing platform for academic research. As a part of the disciplinary institution, analyzing preprint platforms’disciplinary characteristics and innovative develop⁃ment path is beneficial for them to serve the needs of disciplinary development more accurately. [Method/process]Through literature analysis and online research, firstly, analyze the relationship between discipline classification, disci⁃pline institution, and academic publication; secondly, by describing the disciplinary characteristics of preprint plat⁃forms of China and abroad, analyze the problems and challenges they face under disciplinary institution; finally, based on the disciplinary institution, suggestions for the innovative development of preprint platforms are proposed. [Result/conclusion] The development of preprint platforms needs to focus on the following aspects: consolidating the strength of the academic community and creating a high-quality distribution center for various disciplines; to serve the disci⁃pline construction demand and promote academic development in new fields such as interdisciplinary studies; fully uti⁃lize modern digital technology to achieve a knowledge production mode of human-machine collaboration.
