Abstract

Through building an indicator system for evaluating the marine sci-tech innovation ability of China’s coastal provinces, this paper made a comparative analysis on marine sci-tech innovation ability of 11 coastal provinces in 2011-2013 by the principal components analysis (PCA) method. It found these coastal regions can be divided into three levels. Guangdong Province belongs to the first level because its marine sci-tech innovation ability is relatively high. On this basis, it analyzed changes in marine sci-tech innovation ability of 11 coastal provinces with the aid of DEA’s Malmquist productivity index model. Results indicate that the overall marine sci-tech innovation ability of 11 coastal provinces is rising, but there is significant difference between provinces and the influence of regional economic development level is not considerable. Technical progress is main driver for promoting marine sci-tech innovation ability of Guangdong Province and major factor influencing ranking of total factor productivity.
