本文以综合前人对海洋生态资本的测度,估算出我国沿海十一省市近十年的海洋生态资本,并以超效率DEA模型为核心,以海洋生态资本等为投入,以海洋生产总值为产出,计算了沿海十一省市2003~2013年十一年间的海洋生态资本效率,再依据三阶段DEA模型的思想,剔除了陆域经济因素对其的干扰,得到海洋生态资本效率的实际值。结果表明,受陆域经济因素干扰的海洋生态资本效率与实际值有很大的差异,且各省市差异情况并不相同,并基于此得出经济和生态效率的耦合程度得到了显著改善,但经济与生态效率发展并不同步的结论,我国海洋经济与生态协调发展的态势依然严峻。
Based on the previous measurements of marine ecological capital, this paper estimates the marine ecological capital in the past ten years in 11 provinces and cities along the coast of China. Taking the super-efficient DEA model as the core and the marine ecological capital as input, For output, the eco-capital efficiency of the oceans in eleven provinces and municipalities during the eleven-year period from 2003 to 2013 was calculated. Based on the three-stage DEA model, the disruption of land-based economic factors and the efficiency of marine eco-capital Actual value The results show that the efficiency of marine ecological capital interfered with by land-based economic factors is greatly different from the actual value, and the differences among provinces and municipalities are not the same. Based on this, the coupling degree of economic and ecological efficiency has been significantly improved, however, Economic and ecological efficiency is not synchronized with the development of the conclusions of the coordinated development of China’s marine economy and ecological situation is still grim.
