Voluntary certification that signals nonprofit organizations’ legitimacy has been found to be positively related to charitable donations in Europe and North America. However, whether these proxies of organizational legitimacy matter under authoritarian regimes where political connections are deemed critical for resource acquisition has not been explored. Based on a sample of 2,021 Chinese foundations, this article finds that organizational legitimacy achieved through certification is tied to an increase in charitable donations. Meanwhile, organizational legitimacy tends to negatively moderate the relationship between foundations’ political affiliation and charitable donations. That is, certification lifts the amount of charitable donations to civic foundations that are not formally affiliated with the state more than it does for politically affiliated foundations. As the first quantitative study on the effect of voluntary nonprofit certification programs on charitable donations outside Western democracies, this article contributes to our understanding of fundraising in China and other authoritarian states.
