Based on the statistical data in the coastal area from 2001 to 2011，through the construction of the Marine environment comprehensive index include environmental factors in Marine economy total factor productivity measurement framework，and then based on SBM directional distance function and Luenberger productivity index to measure ocean economic total factor productivity and factor analysis. Study conclusion shows that：the study period，the ocean economy total factor productivity is on the decline. The decomposition of total factor productivity results from Marine economy，Marine technology frontier invagination Marine economy is the main reason for decline in total factor productivity. In addition from the decomposition of total factor productivity the causes of this phenomenon also includes the lack of marine output taking into account environmental constraints China’s coastal provinces and the three regions of the marine productivity have emerged large Scale rise.
