本文以沿海省区市为研究对象，利用核密度估计法和SPSS系统聚类法，对沿海地区2000～2013年海洋经济发展水平和海域承载力耦合度与耦合协调度进行分析。结果表明：（1）沿海11个省区市海洋经济发展水平和海域承载力空间分异明显，海洋经济的发展高于海域承载力的增强；（2）11个省区市海洋经济发展水平与海域承载力的耦合度范围处于高水平耦合，耦合协调度范围为0.65～0.84，耦合协调度水平波动增长，逐渐趋于最优状态；（3）沿海地区11个地域单元分为三个类型：高耦合—高发展水平、高耦合—中高发展水平和中高耦合—低发展水平。
Selecting coastal provinces and cities as the research objects，using kernel density estimation method and SPSS system clustering method，the article analyzes the characteristic of space and time series of marine economic development level and the bearing capacity of waters coupling and coupling coordination degree in coastal regions from 2000 to 2013. The result shows that：（1）There is great spatial differentiation between the marine economic development level and the bearing capacity of the waters in coastal regions，and the development of marine economy is higher than the bearing capacity of waters of reinforcement；（2）11 provinces and cities are at a high level coupling for coupling ranging from 0.96 to 1.00，and coupling coordination degree ranges from 0.65 to 0.84，which fluctuations in growth for the optimal state gradually；（3） 11 regional units of coastal area are divided into three types：high coupling-high development level，high coupling-mid-high level of development and high coupling-low development level to formulate development plan in accordance with the regional characteristics，comprehensive，balanced and sustainable development in coastal Marine economy.
