海域空间利用经济效率衡量及其规划治理研究动态OACHSSCD

Marine space is an important component of national territory.The rapid expansion of construction-related sea use and its increasingly prominent contradiction with low utilization efficiency have become evident,while issues of three-dimensional overlapping of sea use projects have emerged,urgently requiring clarification of the trade-offs in sea use efficiency.Using bibliometric software,this study analyzes domestic and international research literature on aquaculture,shipping,tourism,mineral extraction,and offshore wind power under the theme of sea use,identifying research trends in the economic efficiency of marine spatial utilization.The findings reveal that:(1)Economic efficiency of marine spatial utilization has become a key indicator for sea management and control.Stochastic Frontier Analysis and Data Envelopment Analysis are commonly methods for measuring economic efficiency.However,analytical paradigms remain limited to logic paths based on input-output models,improving desirable outputs or establishing comprehensive evaluation indices.Rarely have studies examined endogenous factors of marine economic efficiency from the perspectives of marine spatial utilization structure and sea control elements.(2)Marine spatial planning primarily focuses on the endogenous relationship between sea functional zoning and marine"dual evaluation(carrying capacity evaluation of resources and environment and suitability evaluation of territorial space development)",refining access lists and standards for(elastic)sea use while encouraging regional optimization of sea use planning to enhance use efficiency.(3)The marine functional zoning,three-dimensional compatible utilization of sea areas,spatial elastic access,and intensive sea use control required in the marine spatial planning formulation process all point to sea area use efficiency as a measurement indicator.Future research should prioritize exploring efficiency rules with binding and expected characteristics under different functional zone scenarios,and propose more operational control logic chains and indicator clusters for sea area management that consider three-dimensional stratification.
