This study widely replicates the original studies by Zhan and Tang to verify the impact of political opportunities and the resources of organizations on policy advocacy, which uses a much larger sample of nongovernmental organizations (NGOs) who engage with social work. The main findings of the present study are similar to those of the original studies. First, the study finds that the higher the level of government support, the more likely NGOs is to engage in policy advocacy. Second, the NGOs with stronger political connections are more active in policy advocacy. Third, the income of an organization also has a positive effect on policy advocacy. However, the number of full-time staff, location, and the level of registration of an organization does not have a significant effect on policy advocacy. The study increases the understanding of policy advocacy and the relations between the state and society in China.
