中国海洋渔业生产效率时空格局及影响因素研究OA

This study investigates 10 coastal provinces in China from 2010 to 2023.By constructing a super-efficiency SBM model incorporating undesirable outputs,we measure marine fishery production efficiency(MFPE)and analyze its spatiotemporal evolution and driving forces using the standard deviational ellipse(SDE)and geographical detector model.The findings reveal:(1)China's MFPE exhibits fluctuating trends with significant regional disparities.(2)Temporally,MFPE experienced strong volatility before gradually improving;spatially,its centroid shifted along a"south-north-south-north"trajectory.(3)Influencing factors demonstrate marked spatiotemporal heterogeneity in their impacts.Based on these conclusions,we propose policy recommendations:(1)Establish a differentiated governance system with a primary focus on ecological priorities.(2)Enhance and refine the policy support framework for the integrated development of the three Marine economic zones,while innovating the approach to regional collaborative governance.(3)Promote innovation-driven development,digital transformation,and institutional optimization in marine fishe ries.
