摘　　要：由于传统DEA方法在对决策单元的效率评价及效率影响因素的分析上存在缺陷,本文运用基于自助抽样的DEA方法,利用我国12个主要沿海城市的相关数据,对它们的海洋经济效率值进行了测算,同时分析了影响沿海城市海洋经济效率的因素。研究发现,经济愈发达的沿海城市其海洋经济效率未必更高,但海洋经济发展水平对沿海城市海洋经济效率具有正向影响。同时,外贸依存度高的沿海城市海洋经济效率实际更低,表明其海洋资源可能存在过度开发的问题。此外,加强沿海城市的环境保护力度、改善环境治理有助于海洋经济效率的提升。Because the traditional DEA method has defects in the evaluation of the efficiency of decision-making units and the analysis of the influencing factors of DMU^s efficiency,this paper uses the DEA method based on bootstrap to use the relevant data of 12 major coastal cities in China to evaluate their marine economic efficiency.The calculations were carried out,and the factors affecting the marine economic efficiency of coastal cities were analyzed.The study finds that the economic efficiency of coastal cities with more developed economy is not necessarily higher,but the level of marine economic development has a positive impact on the marine economic efficiency of coastal cities.At the same time,the economic efficiency of coastal cities with high dependence on foreign trade is actually lower,indicating that their marine resources may have over-exploitation problems.In addition,strengthening environmental protection in coastal cities and improving environmental governance will contribute to the improvement of marine economic efficiency.
