摘　　要：文章基于非期望产出的超效率SBM模型,测算2007—2016年中国海洋渔业生态效率,运用标准差椭圆刻画其时空分异特征,并引入广义矩估计模型分析其影响因素。研究结果表明:中国海洋渔业生态效率呈现波动上升的趋势,但整体仍处于较低水平,有较大的提升空间;海洋渔业生态效率较高的地区为江苏、广东和山东,生态效率中等的地区为浙江,生态效率低的地区为辽宁和福建,生态效率无效的地区为河北、广西和海南;海洋渔业生态效率空间分布的重心整体向东南方向偏移,且空间格局在南北方向呈扩张状态,在东西方向呈收缩状态;海洋渔业的产业结构、环境规制和科技支撑对海洋渔业生态效率的提升起正向作用,而对外开放程度对海洋渔业生态效率的提升起负向作用。The super-efficiency SBM model based on undesired output was used to calculate the marine fishery ecological efficiency in China from 2007 to 2016. The standard deviation ellipse was used to characterize its spatial-temporal differentiation characteristics, and a generalized moment estimation model was introduced to analyze the influencing factors. The results showed that the ecological efficiency of marine fishery in China showed a fluctuating upward trend, but the overall level was still at a relatively low level, and there was still much room for improvement in the ecological efficiency of marine fishery. The areas with high ecological efficiency of marine fishery were Jiangsu, Guangdong and Shandong, the areas with medium ecological efficiency were Zhejiang, the areas with low ecological efficiency were Liaoning and Fujian, and the areas with ineffective ecological efficiency were Hebei, Guangxi and Hainan. The center of gravity of the spatial distribution of marine fishery ecological efficiency in coastal shifted to the southeast as a whole. The spatial pattern of marine fishery ecological efficiency was expanding in the south-north direction and contracting in the east-west direction. Marine fishery industry structure, environmental regulation and scientific and technological support had positive effects on the improvement of marine fishery ecological efficiency. The degree of opening to the outside world played a negative role in improving the ecological efficiency of marine fisheries.
