摘　　要：中国海洋经济近年来快速发展，但地区差异明显。以沿海11个省市区为研究对象，从时间与空间2个角度，运用变差系数及加权变差系数来表现1996～2010年沿海省市经济发展的差异程度，结果表明中国沿海省市海洋经济成倍增长，总体差异在波动中减小；采用区位熵、洛伦兹曲线及基尼系数对海洋产业结构及其空间布局演化进行分析，得出海洋产业结构向高级阶段演进，海洋产业集聚规模有所减弱，各产业趋于均衡发展；具有资源属性的海洋产业集聚程度最高，海洋第三产业集聚程度降低：利用主成分分析法对沿海省市的海洋经济发展进行综合评价将其分为3个梯队；使用R／S分析法对沿海地区差异情况进行预测，显示未来差距有增大的趋势。最后从提高海洋资源开发能力、提高海洋经济发展质量等角度提出了具体建议。The marine economy of China is growing rapidly in recent years. Due to the differences in terms of the regional natural resource endowment, technology, industrial foundation, development and policy etc., there are large economic disparities among coastal regions. It takes 11 coastal provinces and municipalities as the ob- jects to study the differences in characteristics of marine economy development in China from the two aspects of space and time in the article. The article uses Variation Coefficient and Weighted Variation Coefficient to represent the differences of coastal regions from 1996 to 2010. It adopts the Location Entropy, Lorezn Curve and Gini Coefficient to analyze the marine industrial structure and the evolution of its spatial distribution. Prin- cipal component analysis is used to evaluate the comprehensive marine economic development of the coastal provinces and the R/S analysis is used to forecast the disparities of the coastal regions. Then some reasonable suggestions are put forward to the existing problems in the development of marine economy. The results show that： marine economy in coastal regions has multiplied while there is a significant regional disparity and the overall difference decreases in volatility. Marine industrial structure is evolving into the advanced stage, the proportion of marine secondary and tertiary industry exceeds the primary industry and the marine secondary in- dustry develops slowly on the whole. The scale of marine industrial agglomeration is reducing and tending to the balanced development. The marine industry with resource attribute has the highest concentration degree and the marine tertiary industry with spatial accessibility has the lower cluster. The coastal provinces and cities are divided into three echelons through comprehensive evaluation. Zhejiang, Shandong, Shanghai, Guangdong and Fujian are in the first echelon of integrated development of the marine economy, Liaoning, Tianjin and Ji- angsu are in the second, Hainan, Hebei and Guangxi are in the thi
