With a clear agenda to reform the public service system and promote a service-oriented nonprofit sector, the Chinese government has been building a local service system by contracting with nonprofit organizations (NPOs) at the community level. Through the competing institutional logics perspective, this article examines the challenges that NPOs experienced and their responding strategies. The study found that bureaucratic logic, managerial logic, professional logic, and guanxi relations logic coexisted in the service field and each had different expectations of NPOs. In juggling the various requirements of these competing institutional logics, NPOs faced three major challenges: powerless status, legitimacy crisis, and accountability dilemma. Nevertheless, they were committed to the community and demonstrated agency in addressing these challenges. The strategies they used included using an intermediary platform to reduce power imbalance, compromising to share legitimacy with neighborhood committees, establishing professional identity, building community, and meeting both upward and downward accountability.
