Abstract:

Based on the three stage super-efficient SBM-Global model, standard deviation ellipse and centroid coordinate method, the marine economic efficiency of 11 coastal provinces and cities of China in 2000-2015 years is calculated and analyzed with the time and space. Research discovery: ① Compared with the first stage, the efficiency of marine economy in the third stage has increased overall, and the ranking of provinces and cities has changed differently. ② In the evolution of time: The efficiency of marine economy in all coastal areas of China has been on the rise, and the absolute and relative difference has been increasing and the relative difference changes relatively smooth. ③ In space evolution: The national standard deviation ellipse was distributed in the Northeast-Southwest pattern and its area increased from small to large. The efficiency distribution changes from the contraction trend to the dispersion trend and finally in the three level pattern of North, Middle and South, which is in accordance with the three major marine economic circles. The standard deviation ellipse area of the three major marine economic circles is gradually reduced, and polarization appears in the efficiency distribution. ④ There is a nonlinear relationship between development level of land area economy, marine economic location entropy, human capital of marine scientific research, marine environmental protection technology level and marine economic efficiency; land economic development level, the level of marine industrial structure, the government's support for marine science and technology has a significant positive impact on it, and the level of opening to the outside world has no significant impact on it.

Key words: marine economic efficiency, three stage super efficiency SBM-Global, standard deviation ellipse, center of gravity transfer, panel threshold model, coastal areas, China
