Most published studies on RRI focus on the social benefits of research and innovation through examining RRI＇s definitions and approaches for its implementation. In contrast, the present study addresses the influence of RRI on economic growth, and discusses the situations in which RRI will benefit economies. Our study finds that for its implementation to be successful RRI needs to meet certain conditions, and that its implementation is not always beneficial to economic growth. To achieve a better result from RRI as part of an innovation policy, each country should balance the push and pull power of RRI to make sure that it becomes a building block rather than a stumbling block for innovation, economic growth and social welfare. To assure that RRI can be successfully implemented, China needs to strengthen and improve the participation mechanisms for stakeholders in major scientific and technological innovative activities.展开更多
