With respect to the features of EcoIndustrial Park (EIP), the government plays an indispensable role during the construction of EIP. In this paper, the function orientation of government has been analyzed during the construction of EIP by discussing the ways to realize EIP. The research results show that the main three functions of government are to provide systematical encouragement as well as planning and coordination services for the development of industrial symbiosis network, to guide and participate in infrastructure construction and “integration of utilities”, and to ensure the formation of park ecology by the way of microregulation and macromanagement.
