This study aims to explain Environmental Regulation Modeling in the Halimun Salak Regional Green Economy Efficiency: Empirical Evidence from the National Park which is expected to be a sustainable solution in supporting the creation of a balance between the economic and environmental concepts, especially in the Halimun Salak national park area, Bogor, Indonesia. The research method used is a qualitative method with a grounded theory approach. The results show that the current environmental regulatory modeling has not been successful in implementing green economy efficiency in the salak forest area. This is evidenced by the findings that there are overlapping regulations, low economic income, the increasing population in the salak forest area, and the lack of resolution of legal protection cases. As well as the implementation of environmental policies to date is still in the form of command and control, which causes discrepancies between the parties that are interrelated. As a result, it is necessary to change the environmental policy model for forest areas, namely by using the rational choice theory model. This policy model will become a new solution in implementing increasingly dynamic policies following changes in human behavior and technological developments. Environmental policies that are made must be a role model in an open and dynamic implementation.
