Abstract:From our marine science and technology investment, science and technology, socio-economic development of the three aspects of marine science and technology competitiveness evaluation index using entropy weighting for empirical analysis. Finally, the introduction of spatial weight matrix, with the spatial econometric model on the analysis of the factors affecting the competitiveness of science and technology of the sea. Results showed that: in research period within, China coastal provinces area marine technology competitiveness has obviously zone sex and space distribution differences sex, formed North to Shandong, and East to Shanghai, and southern to Guangdong for core of space distribution pattern; marine technology on social economic support role most obviously of 3 a province, and city respectively is: Tianjin, and Shanghai and Fujian province; marine technology talent structure on marine technology competitiveness effect maximum and most significantly, marine second industry accounted for than high on marine technology development has negative to role, Practitioners improve technology literacy levels can enhance the competitiveness of marine science and technology.
