Abstract

Based on the unexpected output network SBM-DEA model, this study calculates the efficiency of marine science and technology, green efficiency of the marine economy, and comprehensive efficiency in 11 coastal provinces and cities in China from 2006 to 2017. The influencing factors of two-stage efficiency and comprehensive efficiency are tested by a panel tobit model. The results show that (1) the marine comprehensive efficiency in China from 2006 to 2017 is low, with an average of 0.581. The comprehensive efficiency has not achieved DEA effectiveness, because the efficiency of the first stage is less than 1. The green efficiency of the second stage is generally better than that of the first stage; and (2) among the influencing factors, the development level of the marine economy has a significant positive effect on the second-stage efficiency and comprehensive efficiency. Finally, the author suggests optimizing the input-output efficiency of marine scientific and technological resources, accelerating the transformation of marine scientific and technological achievements, and continuing to promote the development of the marine economy to improve the comprehensive efficiency of the marine economy.
