Abstract:

:This article measures the marine ecological efficiency of 11 coastal regions in China with the SBM model considering the undesirable output. The center of gravity model is applied to projecting and visualizing the evolution of spatial pattern of marine ecological efficiency from 2001 to 2015. On this basis, the VAR model is introduced to explore the dynamic relationship between spatial evolution of marine ecological efficiency and its influence factors.The results showed that: 1) The marine ecological efficiency of coastal provinces is generally low but shows an upward trend. Among them, the marine ecological efficiency of Tianjin, Shanghai, Jiangsu, Fujian and Guangdong jumped from relatively ineffective to relatively effective, and Liaoning,Shandong and Hainan rose from relatively ineffective to relatively inefficient, while Hebei, Zhejiang and Guangxi remained relatively ineffective. 2) The transition process of the gravity center of marine ecological efficiency can be divided into "northeast migration phase from 2001 to 2006" and "southwest migration phase from 2006 to 2015", however, the movement range of of the center of gravity is mainly located in the Yangtze River Delta region. 3) By analyzing the influence factors on the evolution of spatial pattern of marine ecological efficiency, we can find out that the impact of marine industrial structure on marine ecological efficiency has fluctuations between positive and negative but mainly positive. As the industrial structure is continuously optimized, the negative effect is weakened over time. Marine science and technology have a significant positive effect and sustained benefits on marine ecological efficiency, especially in the initial stage of the change of marine ecological efficiency. As a terminal treatment, the effect of environmental regulation on the marine ecological efficiency is not significant.

Key words: marine ecological efficiency, barycenter model, VAR model, coastal regions of China
