This Study explores what account for the factors that promote regulatory reform for sustainable energy development. The findings suggest that policy decision makers' recognition and willingness significantly promotes regulatory reform for renewable energy and energy efficient use technology development. In addition, complicated procedures and environmental protection organizations substantially influence the regulatory reform for renewable energy development and varied network activities have significant impact on the regulatory reform for energy efficient use technology development as well. The final interesting findings are that economic conditions and private development organizations emphasized in conventional economic development are still significant in green economic development. Korean local governments need to pay attention to these finding to efficiently reform regulations for green economic development.
