Trans-regional Collaborative Governance of Major Ecological Infrastructure

Major ecological infrastructure (MEI) plays an important role in supporting regional, national and even global ecological security. From the perspective of spatial governance, in this article: 1) The concept scope, function and significance, development process of trans-regional collaborative governance of MEI are sorted out; 2) The four major development stages and characteristics of trans-regional governance of MEI in China are reviewed, and the main challenges currently facing are analyzed; 3) An analytical framework for trans-regional collaborative governance of MEI is constructed from the three aspects of governance logic, governance structure and implement approach; 4) A practical framework of trans-regional collaborative governance of MEI is constructed from the three dimensions of functional synergy, social collaboration and management coordination; 5) The main objectives, orientation and strategic of trans-regional collaborative governance of MEI are discussed at the national level, urban agglomeration level and metropolitan level respectively; 6) Finally, the implementing guarantee of trans-regional collaborative governance of MEI in China is considered from the aspects of optimizing the institutional environment, establishing the social foundation, and improving the governance timeliness.
