The article analyzes the concept of “spatial balance” of water resources from the perspective of regional economy

and discusses the new trend of economic development in the north and south. To address the emerging issue of uneven development between the north and south

it is required to accelerate the resolution of water resource constraints in the northern region

in order to unleash the development opportunities and potential of other advantageous factors

the article further proposes policy recommendations to strengthen the top-level planning and design of coordinated development between water resources and the economy and society

accelerate the exploration and establishment of a strategic reserve system for water resources in the northern region

incorporate the payment responsibility for water resources strategic reserves into the central government's authority
