Some issues have been extensively discussed in the existing achievements, such as the definition, basic concepts, categories, advantages, historical evolutions, development motivations, obstacles, challenges and routes, goals, characteristics and tools, policies and practices of open science. However, there is a lack of systematic research on domestic open science policies, practice surveys, development models, implementation paths, and evaluation. [Originality/Value] This study clarifies the research achievements, shortcomings and future research directions, though exploring and analyzing the viewpoints of open science research results.
