River is an origion of lives. It seems there is a renowned river flowing through in all the metropolitan cities.Many rivers have been polluted due to economic development, which has brought destructive impact on the environment and the quality of life. People begin to realize that the aim is switiching from economic development to preservation of the environment. The government, public organizations, and the public are all interested in balancing economic development and environmental preservation. Kaohsiung city is municipal , comparing with Kaohsiung county; both are ruled by two different levels of administrations under differing budget. Due to jurisdictions overlapping, Kaohsiung city and county failed to manage the Love River together, which is in need of restructuring the Policy Network, New Managerial Regime, and Collaboration. The Policy Network is to be revised to increase efficiency on the policy community, issue network, professionalized network, intergovernmental network, territorial network, and product network. For effective management of the Love River, there are four areas including the driving force, the public opinion, the interests of the state, and the economical/environmental response. We wish to find out a solution on Love River management which benefits the economy, the society, the ecosystem, and the environment, by reconstructing the current system to build up a cooperative relation between the city and county of Kaohsiung, in order to improve the water quality of the Love River. By consecutive interviews and thorough research of using the quality analysis software, ATLAS.ti, we analyzed the data and set a coding system that ranks the importance of various factors involved in the Love River management, which improves management base on the new method of management more than just geography. We suggest that the state and local authorities stay neutral from own political goals, and seek for consensus in decision-making. This brings in a competitive atmosphere of cooperation, quality, and relationship development between the responsible authorities and the public. The successful system of cross-area management is to be well-organized, strategic, active ,leadership and management guidance effective,these five factors enable the long-term management mechanism of the Love River .
