The development of marine science and technology (S&T) is essential to build a country with advanced marine industry. In general, the increasing investment in S&T is a practical measure to improve China's marine S&T rapidly. However, two problems emerged: (1) the increasing investment is the first requirement, but not the unique requirement to promote the marine S&T innovation capability; (2) compared with China's marine natural resources, the shortage of marine S&T resources, especially high-end talent, is more serious. Therefore, the efficiency of marine S&T should be paid more attention in the course of development of marine S&T and construction of a marine powerful country. In this paper, Stochastic Frontier Analysis (SFA) was used to measure the total factor productivity (TFP) index of marine S&T, and Exploratory Spatial Data Analysis (ESDA) and Spatial Panel Econometric Models were applied to identify the temporal and spatial distribution pattern and influencing factors from 2006 to 2011. The results showed that TFP of marine S&T in China during 2006-2011 was driven by technological advancement, and its regional growth pattern changed from several poles to a single pole. TFP of marine S&T remained higher values in the areas with low development level, which contribute to narrow the gap among inter-regional marine S&T continuously. Large proportion of traditional marine industries had a negative effect on marine S&T, while other aspects (i.e., technological literacy of practitioners, industry-university-research cooperation etc.) could improve marine S&T effectively. At last, based on the research results ,we proposed the following suggestions for China's marine S&T development: (1) The flow of marine S&T production factors among different regions should be strengthened in order to make full use of the existing space spillovers of marine S&T; (2) The introduction of marine technology should be enhanced, and the application capabilities and allocative efficiency of existing technologies should be improved, which could promote technology transformation and application; (3) The economic level and industry structure of coastal provinces should be optimized; (4) The inter-regional public cooperation platform should be built, including innovating the research cooperation and strengthening the building of marine industry infrastructure; (5) The role of the market in the allocation of S&T resources should be enhanced.
