The Impact of Environmental Regulation on Ecological Efficiency of Marine Fisheries in China and The Spatial Difference of Ecological Efficiency
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.
