Policy support matters for the success of public policies. It is still unclear how governments can garner support for policies with high costs. Using a conjoint experiment in China, we demonstrate that governments can encourage policy support by offering institutional services and material interests to policy targets. In particular, citizens become more willing to support policies when governments timely disclose policy information and respond to and incorporate their voices in the policy design. Government subsidies in both the short and long runs also increase citizens' policy support. In addition, government transparency and long‐run subsidies are complementary to enhancing policy support; the role of institutions is strengthened when citizens are exposed to severe policy problems.
