Effective marine conservation requires science‐based decisions and strong support from the public and local communities. Understanding the potential social influence of scientists and nongovernmental organizations (NGOs) in marine conservation is key, yet this aspect has been underexplored in conservation social science. In this study, we created a simple index of potential social influence (PSII) for scientists and NGOs, initiating an analytical framework to identify key variables correlated with the PSII and their underlying pathways. We illustrated this framework using China as a case study, where marine conservation advancement is urgently needed. Our results indicated that many of the variables we identified were correlated with the PSII, even though some are rarely mentioned in the related literature. Notably, both communication capability and annual funding positively impacted the potential social influence of scientists and NGOs, albeit through different pathways. This study provides valuable insights to enhance marine conservation efforts in China and addresses a critical research gap in assessing social influence on nature conservation.
