The issues and solutions reviewed within the Local Agenda 21 are almost the ranges in dealing with local activities. Thus, the local government involvement and cooperation will be the critical factors to determine if it is available for national eternal management in the future. On the eternal management, the local government bodies are playing the very important roles for the realized tasks because local government bodies emphasize the public affairs to serve local regions and also hold the duty to improve local environment and life quality. Meanwhile, despite the small duty ranges of local government bodies, they actually own much on autonomy management. They can directly and effectively promote and implement various public measures. In addition, the local eternal management is featured with the characteristics varying with locations. Because the establishment and research about sustainable development systems is not only a nationwide issue but also the issue focused by the efforts made by cities, communities or even business organizations. Within this research, we make the research criteria based on the Kaohsiung City-Kaohsiung County-Pington County Sustainable Development Strategy Report. By using questionnaire survey, we focus on the eternal development strategies of Pington County. Also, through the research goals about overall regional sustainable development, we insightfully investigate the sustainable development courses and strategies about Pington County only. Seeing from the execution of eternal development policies locally, the single local government body will make the materialization of local eternal development easier and more harmoniously. By referring to cases about the sustainable development activities made by Kigmen County, Hualien County, Tainan County, Yilan County and Changhua County, totally 5 county government bodies, we investigate the research courses, methods and strategies of sustainable development activities of local county governments. Also, based on the research basis of Kaohsiung City-Kaohsiung County-Pington County Sustainable Development Strategy Report, we make further efforts for professional questionnaires in dealing with the sustainable development strategies of Pington County. Through 4 dimensions separately of environment, society, economic and systems, we create 43 issues about the eternal development of Pington County. Also, we focus on these issues for the upcoming efforts which shall be made by Pington County for their own eternal development goals so that our research can be available for the reference made by Pington County to execute their own eternal development strategies.
