In China, both governments and civil institutions play important roles in non-profit regulation. However, with various regulatory instruments available, it remains unclear which has the strongest public support and most effectively promotes civic engagement. This study compared the impact of different non-profit regulatory instruments addressing information disclosure on two aspects of civic engagement intention: willingness to donate and willingness to volunteer. A survey experiment was conducted to analyse the perspectives of 939 Chinese participants on four types of regulation: no regulation, civil regulation, accommodative government regulation and deterrent government regulation. Results showed that regulation was preferred to no regulation and deterrent government regulation was preferred to accommodative government regulation, which was preferred to civil regulation. Additionally, public trust in non-profits significantly mediated the relationship between regulation and civic engagement intention. These findings suggest that government regulation, particularly the deterrent approach, garners strong public support and may be prioritized within the Chinese context.
