中国海洋科技产出效率实证分析：基于典型相关和DEA-Malmquist

he output efficiency of ocean technology of 13 regions of China is analyzed by using the methods of canonical correlation analysis and DEA-Malmquist based on the annual data of 2006 to 2012. And the results show that the total factor productivity of China's marine science and technology is growing during the period，but the regional difference is significant and the technical efficiency is quite low. Furthermore, the growth of output and the improvement of efficiency of ocean technology are significantly related to the increase of input in recent years. Therefore, in order to increase the output and improve the innovation efficiency further，the pure technical efficiency and technical transformation capacity should be improved, and more research talents should be introduced and cultivated.
