| 运用非期望产出超效率SBM模型测算2010—2020年海洋渔业碳排放效率,采用GC-TOPSIS综合评价模型测算海洋渔业经济和科技的综合发展指数,并用耦合协调模型和核密度估计分析中国10省(自治区、直辖市)海洋复合系统协调发展的时空演化特征。结果表明:(1)时间序列上,海洋渔业碳排放效率的综合发展水平变化幅度较大,呈现波动上升的态势,海洋渔业经济、科技的综合发展水平、海洋渔业碳排放效率-经济-科技三者耦合度和耦合协调度呈现出稳步上升的态势。(2)空间特征上,耦合协调度呈现出东部海洋经济圈>南部海洋经济圈>北部海洋经济圈的格局,形成了北部以山东为核心、东部以江苏为核心和南部以广东为核心的空间结构。(3)主要障碍因子上,准则层方面,排名前3的障碍因子分别为科技产出、渔业投入和经济结构,其中科技产出是所有省份的第一障碍因子;指标层方面,海洋专利授权数、海水养殖面积、发表海洋科技论文数和海洋渔业总产值出现的频次最高,因此应提高科技转化能力,发挥海洋渔业科技的作用。 |

| Abstract: |
| The non-expected output super-efficiency SBM model was used to measure the carbon emission efficiency of marine fisheries from 2010 to 2020, the GC-TOPSIS comprehensive evaluation model was used to measure the comprehensive development index of marine fisheries economy and science and technology, and the coupled coordination model and kernel density estimation were used to analyze the spatial and temporal evolution characteristics of the coordinated development of the marine composite system of the 10 provinces (municipalities and districts) in China. The results show that:The results show that:(1) on the time series, the comprehensive development level of carbon emission efficiency of marine fisheries has a large change in amplitude, showing a fluctuating upward trend, and the comprehensive development level of marine fisheries economy, science and technology, the coupling degree and coupling coordination degree among carbon emission efficiency, economy, and technology in marine fisheries have shown a steady upward trend. (2) In terms of spatial characteristics, the coupling coordination degree of carbon emission efficiency, economy, and technology in China′s marine fisheries shows a spatial pattern of eastern ocean economic circle > southern ocean economic circle > northern ocean economic circle, forming a spatial structure centered on Shandong in the north, Jiangsu in the east and Guangdong in the south.(3) On the main obstacle factors, on the guideline level, the top three obstacle factors are scientific and technological output, fishery input and economic structure, of which scientific and technological output is the first obstacle factor for all provinces, and on the indicator level, it is found that the number of marine patent authorizations, the area of marine aquaculture, the number of published marine scientific and technological theses, and the total output value of marine fisheries have appeared with the highest frequency, so that the transformation capacity of science and technology should be improved and the role of marine fishery science and technology. |
