摘要
环境规制作为保护环境的有效手段对中国海洋渔业治理具有重要的参考价值.文章以海洋渔业为研究对象,运用基于非期望产出的SBM模型对2011-2020年中国沿海9个省(自治区)海洋渔业生态效率进行测算,使用标准差椭圆方法对海洋渔业生态效率的时空特征进行分析,最后运用Tobit回归模型探究环境规制及其他因素对海洋渔业生态效率的影响.研究发现:(1)海洋渔业生态效率整体呈下降趋势,各地区差距并未显著缩小,呈现两极分化的趋势.(2)海洋渔业生态效率重心整体向西南移动,呈东北-西南的空间发展格局.(3)环境规制与海洋渔业生态效率呈负相关,其他影响因素地区发展水平和产业结构与海洋渔业生态效率呈负相关,对外开放水平和科技支持与海洋渔业生态效率不显著.最后,基于研究结论,提出了相关政策建议.
Abstract
Environmental regulation,as an effective means to protect the environment,has im-portant reference value for marine fishery management in China.This paper takes marine fisher-ies as the research object,uses the SBM model based on non-expected output to measure the marine fishery ecological efficiency in nine coastal provinces of China during 2011-2020,and u-ses the standard deviation ellipse method to analyze the temporal and spatial characteristics of marine fishery ecological efficiency.Finally,Tobit regression model was used to explore the im-pact of environmental regulation and other factors on the ecological efficiency of marine fisheries.The findings are as follows:(1)The ecological efficiency of marine fisheries showed a downward trend,and the regional gap was not significantly reduced,showing a trend of polari-zation.(2)The center of gravity of marine fishery eco-efficiency moved to the southwest as a whole,showing a northeast-southwest spatial development pattern.(3)Environmental regula-tion is negatively correlated with marine fishery eco-efficiency,regional development level and industrial structure of other influencing factors are negatively correlated with marine fishery eco-efficiency,and the level of opening to the outside world and scientific and technological support are not significantly correlated with marine fishery eco-efficiency.Finally,based on the research conclusions,this paper puts forward relevant policy recommendations.
