Research and analysis on the spatiotemporal pattern and influencing factors of carbon emission efficiency in the fishery economy of coastal provinces in China
The improvement of carbon emission efficiency in fisheries can effectively reduce carbon emissions and achieve a low-carbon economy,which is of great significance for achieving China's"dual carbon"goals.This study takes 10 coastal provinces in China from 2010 to 2022 as the research object,uses the super efficiency SBM model to calculate the carbon emission efficiency of fisheries,analyzes the spatiotemporal structural characteristics of fishery carbon emission efficiency through standard deviation ellipse,and finally explores the influencing factors of fishery carbon emissions through the STIRPAT model.This research has found that the carbon emission efficiency of fishery economy in some coastal provinces of China is showing a downward trend.The difference in carbon emission efficiency of fishery economy in coastal provinces of China has gone through a process of"decrease-increase-decrease".The carbon emission efficiency of fishery economy in coastal provinces of China has experienced a spatial shift trend from"north-south-north".The degree of specialization,wealth,technological level,and industrial structure in the fishing industry will have a certain impact on the carbon emission efficiency of the fishing economy.Based on the above research findings,reasonable policy recommendations are proposed as followings.Promote low-carbon and environmentally friendly fishery production technologies and methods.Establish and improve monitoring and evaluation of fishery carbon emission efficiency.Develop differentiated carbon reduction strategies.Optimize the structure of the fishery industry.
