Based on the social capacity for environmental management (SCEM) framework, we propose a dynamic process model of SCEM by integrating the three stages of SCEM development, i.e., 1) system making, 2) system working and 3) self-management. The integration is carried out based on government activities. For the system to start, a perturbation is assumed to initiate the system of relationships between environmental actors (government, firms and citizens). The data is compiled from Geo Data Internet portal maintained under United Nations Environment Programme. To estimate the model parameters we have used structural equations with latent variables. Behaviors of SCEM actors at different stages are assumed to be theoretical constructs (latent variable) based on different observed variables that characterize the SCEM stages.
