Research on Temporal and Spatial Ddifferentiation of Green Production Efficiency of Marine Fishery in China Based on SFA Model
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.
