长江经济带新型城镇化对水资源与经济协调发展的影响

Influence of new-type urbanization in the Yangtze River Economic Belt on coordinated development of water resources and economy

水资源刚性约束条件的背景下,把握新型城镇化建设机遇,促进水资源与经济协调发展具有重要意义。基于长江经济带2007—2020年省级面板数据,综合利用耦合协调度模型、中介模型以及空间计量模型探究新型城镇化对水资源与经济协调发展的影响以及用水效率的中介效应。结果显示:新型城镇化对地区水资源与经济协调发展具有促进作用,用水效率在其中起到中介作用;新型城镇化的促进作用存在空间溢出性。据此提出扎实推进新型城镇化建设、稳步推动用水效率提升、强化地区联系、推动区域协同发展等政策建议。

Under the background of rigid constraints of water resources,it is of great significance to grasp the opportunities of new-type urbanization in order to promote the coordinated development of water resources and economy.Based on the provincial panel data of the Yangtze River Economic Belt from 2007 to 2020,the coupling coordination degree model,the mediation model and the spatial econometric model were comprehensively used to explore the impact of new-type urbanization on the coordinated development of water resources and economy and the mediating effect of water use efficiency.The results show that the new-type urbanization promotes the coordinated development of regional water resources and economy,and water use efficiency plays an intermediary role.And the promotion effect of the new-type urbanization has spatial spillover.Accordingly,policy recommendations are put forward such as promoting the construction of new-type urbanization in the region,steadily promoting the improvement of water use efficiency,strengthening regional connections,and promoting regional coordinated development.
