What kinds of social organizations or nongovernmental organizations (NGOs) in China have a greater influence on government policy making and policy outcome? Using a random sample survey of 2,588 social organizations from Beijing, Zhejiang, and Heilongjiang, this article reveals that the new tendency of social marketization, including social entrepreneurship and achieving government contracts for purchasing services, is positively related to the perceived influence on government policy making and the perceived likelihood of achieving policy change. Organizational autonomy is negatively associated with the perceived policy influence and policy change, and corporatist connections are not statistically significant in the estimation. This research finds a positive relationship between social marketization and the perception of policy influence of social organizations, and compares social marketization with civil society and corporatism, the two mainstream approaches to explaining NGO–government relations in China.
