摘　　要：根据2013—2022年长江经济带11个省(市)的面板数据,采用超效率SBM模型和核密度估计对该地区淡水渔业养殖效率的时空分异特征进行探究,并利用地理探测器对长江经济带淡水渔业养殖效率影响因素进行了分析。结果表明,2013—2022年长江经济带淡水渔业养殖发展态势良好,整体上呈波动上升趋势,但是内部分异较明显。其中,东部地区淡水渔业养殖效率有所下降且起伏较大,中部地区淡水渔业养殖效率下降的趋势最为明显,西部地区近年来淡水渔业养殖效率快速上升;在渔业效率中,自然环境要素驱动力>社会经济要素驱动力>生产投入要素驱动力。根据研究结果,对长江经济带淡水养殖渔业的发展提出对策和建议。Based on the panel data of 11 provinces and cities in the Yangtze River Economic Belt from 2013 to 2022,the paper first used the super-efficiency SBM model and kernel density estimation to explore the spatio-temporal differentiation characteristics of freshwater fishery aquaculture efficiency in this region;then the influencing factors of freshwater fishery aquaculture efficiency in the Yangtze River Economic Belt were analyzed by using geographic detector.The results show that the development of freshwater fishery in the Yangtze River Economic Belt is good in 2013-2022,and the overall trend is fluctuating and rising,but the internal differentiation is obvious.The freshwater fishery aquaculture efficiency in the eastern region has decreased and fluctuated greatly,the decline trend of freshwater fishery aquaculture efficiency in the central region is the most obvious,and the freshwater fishery aquaculture efficiency in the western region has increased rapidly in recent years.The fishery efficiency is mainly affected by the level of natural environment,social and economic development and production input.According to the research results,suggestions and countermeasures for the development of freshwater aquaculture fisheries in the Yangtze River Economic zone are put forward.
