Water Ecological Restoration Practice of Cross-Administrative-Area Synergic Projects—Case Study on the Yuandang Lake Synergic Eco-Development Pilot Project,the Demonstration Zone of Green and Integrated Ecological Development of Yangtze River Delta

Today integrated regional development becomes a national agenda of China. The Demonstration Zone of Green and Integrated Ecological Development of Yangtze River Delta faces a task of exploring a more effective and localized coordination mechanism for the implementation of cross-administrative-area synergic projects under the current administrative regimes. This article reviews the current practice of cross-administrative-area synergic development at home and abroad, and summarizes corresponding mechanisms and key issues; then by focusing on the case of the Yuandang Lake Synergic Eco-Development Pilot Project that sits on the junction of Shanghai City and Jiangsu Province, this article sorts out the key issues and the solutions at each project stage, and proposes the “3P3S” coordination framework for the implementation of cross-administrative-area synergic projects. As an exploration of spontaneous bottom-up approach—instead of administrative orders—the “3P3S” coordination framework can efficiently promote project implementation under the current administrative regimes, providing reference for synergic implementation of regular cross-administration-area projects.
