Abstract

The dynamic evolution and regional heterogeneity of fishery efficiency development must be explored from an ecological perspective to reveal the spatial pattern of fishery ecological efficiency. Thus, taking 30 provinces/cities in China between 2006 and 2020 as research objects, we measured the level of the fishery ecological efficiency and regional fishery ecological efficiency convergence indexes using the superefficiency and convergence indexes, respectively. We found the following: (1) The ecological efficiency of China’s fishery shows a wavelike upward trend with significant fluctuations, but the overall efficiency level is not high. (2) The development of regional fishery ecological efficiency is not well coordinated; however, the variation curve of fishery ecological efficiency in the eastern and central regions is gradually decreasing. (3) A trend of “catching up and surpassing” is observed in the development of fishery ecological efficiency in various regions of China, and regional fishery ecological efficiency gradually converges to the regions’ respective steady-state levels over time. The results indicate a significant gap in regional fishery ecological efficiency, as well as polarization; areas with lower fishery efficiency are catching up with high-efficiency areas at different speeds, and regional fishery ecological efficiency is stabilizing.

中国渔业生态效率的动态演化与收敛分析

要揭示渔业生态效率的空间格局，必须从生态学角度探讨渔业生态效率发展的动态演化和区域异质性。因此，本文以2006 - 2020年中国30个省市为研究对象，分别采用超效率指数和收敛指数测度渔业生态效率水平和区域渔业生态效率收敛指数。研究发现:(1)中国渔业生态效率呈波动较大的波浪形上升趋势，但总体效率水平不高。(2)区域渔业生态效益发展不协调;但东部和中部地区渔业生态效率变化曲线呈逐渐减小的趋势。(3)中国各区域渔业生态效率的发展呈现出“赶超”的趋势，随着时间的推移，区域渔业生态效率逐渐趋同于区域各自的稳态水平。结果表明:区域渔业生态效率存在明显的差距和两极分化;渔业效率较低地区正以不同速度赶超高效率地区，区域渔业生态效率趋于稳定。
