Abstract:Coupling coordination development of marine and terrestrial strategic emerging industry system will help promote the rapid development of strategic emerging industries in the coastal areas and accelerate the harmonious development of regional economy,thereby realizing the change from marine power country to marine economic power country.This paper constructed a coupling coordination model between marine and terrestrial strategic emerging industry,building a evaluation system of coupling coordination,we measured the coupling degree and coordination degree based on the statistical data from 2007 to 2012.It turned out that the coupling degree of strategic emerging industries in the coastal areas of china alternated between break-in-type coupling and high level coupling except Hainan, Guangdong has the highest coupling coordination degree and stays at primary and intermediate coordination development level;Hebei has the lowest coupling coordination degree and stays at seriously imbalanced recessional level;other regions roughly centered between moderately imbalanced level and mildly imbalanced level.
