Government resources used for opening data and citizen engagement with open government data (OGD) are expected to have a mutual influence, but this has not been empirically investigated. Therefore, this paper investigates this mutual relationship by measuring both governmental resources and citizen engagement based on resource-based theory. The weight of their measurements is evaluated by the entropy method. Data was collected from 337 Chinese municipal governments to investigate whether governmental resources and citizen engagement with OGD are dependent. The findings by a coupling coordinated model and regression analysis revelated that: Although governmental resources and citizen engagement with OGD have a strong interaction, the coordination between them is low. An explanation for this is that the development of citizen engagement with OGD lags behind the deployment of governmental resources in most Chinese cities. @en
