Mechanism of Cross-border Coordination through Regional Planning for Ecological Goals

At present, the world is facing the common challenge of "sustainable development". Since 2017, the Chinese government has proposed the goal of "High-quality Development", calling for concerted efforts to balance ecological protection and economic growth, refraining from the sole GDP-oriented developing model. Metropolitan areas, in particular, should change the extensive mode of development while balancing protection and development. The goal of green ecology is taken seriously（Bryan B A, et al., 2018）. China is currently undergoing a unprecedented urbanization process across the country，and metropolitan circles have become one of the significant symbols of this urbanization process, in which all kinds of cross-border elements interact frequently , space is developed continuously, and space demand for cross-border development encounters collaboration-conflicts and constrains（BODIN Ö, 2017）. In that case, state governance patterns transformation is more than required than ever, especially considering urbanization at such a scale not only generates economic miracles but results in annoying patterns of unsustainable development, the conflict is a typical problem that needs to be solved in the process of regional governance's transformation. How to realize cross-border spatial governance from a regional perspective has become a common focus of many disciplines such as economics, planning and administration（Hongtao Yi, et al.，2017）. This research focuses on the regional cross-border conflict, building "structure - process " meta-governance model. The study of spatial planning as a coordination tool is committed to solving the defects and functions of regional public governance in China's rapid urbanization areas, and exploring the planning and coordination mechanism in regional collaborative governance. This article mainly answers the following questions： 1) Practical issues of cross-border regional affairs and the dilemma of collective action in ecological issues; 2) Planning Governance Structure of cross-border regions at all levels ; 3) Planning Policy Process of the cross-border regions, the transmission process and interaction of different stakeholders；4) The coordination mechanism in cross-border regional planning，based on the static Planning Governance Structure model and the dynamic Planning Policy Process model；5) Exploration of spatial planning coordination mechanism and governance approaches applicable to cross-border regions such as urban agglomerations, in the context of ecological goals of global sustainable development. This paper selects two typical polycentric urban agglomerations, the Yangtze River Delta region in China and Randstad in the Netherlands, both of which span four provincial administrative units, as spatial objects. This article focuses on the conflict of water system spatial governance in the transboundary region of the Yangtze River Delta and the controversial conservation and ecological restoration of the "Green Heart" and "Green-Blue Delta" in Randstad（Balz V , Zonneveld W, 2018）, based on the theory of meta-governance and collaborative governance in the discipline of public management and urban planning. This paper structurally sorts out the regional planning of the two regions from the 1950s to the present, and conducts textual metrological analysis on more than 100 central and local policies and planning texts. In this study, semi-structured interviews and participatory observation will be carried out in government institutions in the Yangtze River Delta region of China. Land use data will be used to conduct a geospatial econometric analysis of regional spatial change and spatial network, and the efficiency loss and mechanism obstacle of regional spatial planning for realizing regional ecological protection goals in China will be found. In the context of the global regionalization process, this study hopes to provide planning solutions that are conducive to the protection of cross-border blue-green space, and provide governance insights for cross-border regional planning of sustainable development.
