Empirical analyses testing the impacts of entrepreneurial orientation (EO) remain lacking in public sector research despite strong normative expectations for public managers to foster a culture of innovativeness, risk-taking, proactiveness, and accountability in their organizations. Drawing data from a nationwide survey of the US local governments, this research uses structural equation modelling to examine relationships between EO, organizational integration processes, and performance in the Energy Efficiency and Conservation Block Grant (EECBG) programme. The study finds that EO positively influences programme performance, but does so indirectly by enhancing knowledge sharing, interorganizational collaboration, and performance information use. Practical and theoretical implications are discussed.
