Results show that a new Marine industrial development potential, the biggest achieve stability needed for the longest time, second for Marine product, achievestability is faster than traditional Marine industries. Finally, the full text is summarizedand prospected.Article’s innovation lies in:(1) article will control theory to the research of theMarine economy development of our country, slam the door before only in mathematicsand economics theory of monopoly. Added control item in the differential equation, sothat we can better analyze the trend of the development of the Marine economy of ourcountry.(2) this article through to our country Marine economy of power systemresearch, the development of Marine economy has made the development bottleneck ofbold prediction, and "longevity" of the Marine economy development of our country isanalyzed, combining with the reality of our country’s Marine policies and conditions forthe development of Marine economy put forward reasonable Suggestions.
