| 摘 要： | 为应对海洋渔业发展新挑战，促进渔业经济与生态环境协同发展，践行全面协调可持续发展要求。文章基于2009—2019年我国沿海省(自治区、直辖市)数据，运用包含生态环境的随机前沿生产函数、泰尔指数分别量化我国海洋渔业绿色生产效率及其地区差异与变化程度，并对其影响因素进行回归分析。结果表明：(1)2009—2019年我国海洋渔业绿色生产效率呈现逐年上升的趋势，但整体水平仍不高，随着海洋渔业绿色生产效率水平的逐步提升，其增长率呈下降趋势；(2)泰尔指数逐年降低，表明我国海洋渔业绿色生产效率的区域差异正逐渐缩小；(3)海洋渔业经济总产值占地区GDP比重、海洋捕捞产量占海水产品产量比重、渔业从业人员专业化程度、水产技术推广经费对我国海洋渔业绿色生产效率产生显著的正向影响，水产品因污染造成损失产生负向影响。据此提出加强海洋资源监测、强化海洋渔业科技支撑、转变渔业发展模式等对策建议。

| Abstract: | In order to cope with the new challenges of marine fishery development, promote the coordinated development of fishery economy and ecological environment, and practice the requirements of comprehensive and coordinated sustainable development, based on the data of coastal provinces and cities from 2009 to 2019, this paper used the stochastic frontier production function and the Thiel index including the ecological environment to quantify the green production efficiency of marine fisheries in China and its regional differences and changes, and conducted regression analysis of its influencing factors. The results showed that: (1) from 2009 to 2019, the green production efficiency of China''s marine fisheries showed an upward trend year by year, but the overall level was still not high, and with the gradual improvement of the green production efficiency level of marine fisheries, its growth rate showed a downward trend; (2) the Thiel index decreased year by year, indicating that the regional differences in the green production efficiency of marine fisheries in China were gradually narrowing; (3) the proportion of marine fishery economic output value in regional GDP, the proportion of marine fishing output in seawater product production, and the degree of specialization of fishery practitioners, the funding for the promotion of aquatic technology had a significant positive impact on the green production efficiency of China''s marine fisheries, and the loss of aquatic products due to pollution had a negative impact. Accordingly, countermeasures and suggestions such as strengthening the monitoring of marine resources, strengthening the scientific and technological support of marine fisheries, and changing the development mode of fisheries were proposed. |
