Study on the Mechanism of Multi-Scalar Transboundary Water Security Governance in the Shenzhen River

This paper examines the evolution and mechanism of multi-scalar transboundary water governance in the Shenzhen River, flowing through Shenzhen and Hong Kong since the 1980s. The research identifies three phases of governance: negotiation, consultation, and cooperation. It highlights the roles of the Shenzhen government as initiator, the Hong Kong government as collaborator, and the central government of China as participant and coordinator. The analysis indicates that severe flooding events, economic growth, and central government support are key consensus drivers. The research fills a gap in the understanding of transboundary governance, providing insights for improved cooperation and regional development between Shenzhen and Hong Kong.
