Abstract: In order to analyze the degree of influence of science and technology input in China's marine fishery industry，this paper used Cobb-Douglas production function method to build China's marine fisheries scientific and technological progress contribution rate calculation model. Based on 2001—2010 data related to the production of China’s marine fisheries, the contribution rate of scientific and technological progress during the 10th-five-year period and the 11th-five-year period were estimated. The results showed that with respect to the 10th-five-year period, the scientific and technological progress contribution rate of China’s marine fisheries in the 11th-five-year period has increased, but was still at a low level, which indicated that the technological level of China's marine fisheries was lagging behind and the degree of its contribution to the economic development of marine fisheries was low. At last some countermeasures and suggestions on improving the level of scientific and technological development of marine fisheries were proposed, i.e. increasing research investment, improving R & D level, establishing marine fisheries science and technology promotion mechanisms, encouraging and guiding the transformation and enhancing the construction of marine fisheries scientific and technological information system.
