黄河流域农业新质生产力对农业水资源绿色效率的影响OA

Clarifying the mechanism through which new quality agricultural productive forces affect the green efficiency of agricultural water resources is essential for promoting high-quality agricultural development in the Yellow River Basin.The entropy method and Super-SBM model are employed to measure the new quality agricultural productive forces and the green efficiency of agricultural water resources in the Yellow River Basin from 2011 to 2023.A two-way fixed-effects model,mediation effect model,and threshold effect model are utilized to examine the influence of new quality agricultural productive forces on the green efficiency of agricultural water resources.① The overall level of new quality agricultural productive forces in the Yellow River Basin is on the rise.The average green efficiency of agricultural water resources increased from 0.2061 in 2011 to 0.6766 in 2023,exhibiting a spatial pattern characterized by"middle reaches>lower reaches>upper reaches,""semi-humid regions>semi-arid regions,"and"major grain-producing areas>production-consumption balanced areas."② New quality agricultural productive forces have a significant positive impact on the green efficiency of agricultural water resources with heterogeneity,with more pronounced effects in the middle and upper reaches,semi-humid areas,and production-consumption balanced areas.③ New quality agricultural productive forces influence the green efficiency of agricultural water resources through agricultural industry agglomeration,upgrading of agricultural industry structure,and technological progress in agriculture.④ The impact of new quality agricultural productive forces on the green efficiency of agricultural water resources has a threshold limit on the level of economic development.It is recommended to utilize modern production factors to promote the development of new quality productive forces;adopt differentiated policies according to local conditions;and implement phased guidance in line with the stage of development.
