Abstract:

At present, marine economy has become a new bright spot and indispensable part of world economic growth. Marine science has become a frontier area of global competition. In this paper, we have selected the academic papers and patent literature in the field of marine science from 2011 to 2017 in the core collection of the Web of Science and the patent literature of the Derwent Innovations Index. The comparative analysis between the paper and the patent and the patents is carried out by using the co-word analysis and the predicate tree analysis , digging out the technology opportunities of marine science.
