【Aim】 Invasion biology is an emerging discipline in the field of biosecurity. Understanding the development process and current status of invasion biology biology both in China and globally is of significant importance for comprehensively grasping the global situation and frontiers of this discipline, as well as evaluating the scientific capabilities and influences of countries in this field. 【Method】 This study used ten keywords ("biological invasion""invasion biology" "invasion ecology" "invasive alien species" "alien species" "exotic alien species" "exotic species" "non-indigenous species" "non-native species", and "invasiveness") to search the databases such as Web of Science and China National Knowledge Infrastructure (CNKI) to obtain the scientific outputs (including papers and monographs) related to invasion biology. A bibliometric analysis was conducted to summarize and categorize various attributes of the scientific outputs. 【Result】 The period from 1950 to 2024 witnessed the publishing of a total of 117 575 Chinese and English papers and 389 monographs, the proposal of 45 hypotheses related to biological invasions, and the completion of genome sequencing and assembly of 1 463 invasive alien species. Despite a late start in the research on invasion biology, China has made remarkable progress in the past two decades and is now at the forefront of the world in terms of paper output, publications in top journals, number of monographs, leading researchers, and cutting-edge technology. Nevertheless, gaps persist between China and global leaders in this field. For instance, China lacks specialized journals with international influence, and its outputs remain to be improved. The citations of top-journal articles, hypotheses generated, and internationally co-authored papers from China accounted for only 30.0%, 16.7%, and 29.9%, respectively, of those from leading countries. 【Conclusion】 Filling the gaps should be prioritized for future development. The findings of this study objectively reflect the current research status of invasion biology in China and its international position and influence, providing a theoretical basis for pinpointing the future research directions.
