运用超效率DEA视窗模型对我国沿海11个省（市、区）2006－2012年海洋科技的投入产出效率进行评价，进而综合Malmquist指数与聚类分析深入挖掘效率变化的区域差异及原因。研究发现：全国层面上，海洋科技投入产出效率的增长主要得益于管理水平的提升和规模的优化；区域层面上，各省（市、区）的海洋科技投入产出效率变化可分为积累带动型、应用带动型和低增长型三类；驱动效率提升的主要因素存在明显的区域差异，但效率下降则主要源于海洋科技知识积累和改进不够。

This paper applies SE-DEA window model to value the input and output efficiency of marine science and technology of 11 coastal provinces and cities in China from 2006 to 2012. Then, it applies the Malmquist index analysis and clustering analysis to explore the regional disparity and the reasons of efficiency change. The research finds: at the national level, the overall growth of efficiency is mainly caused by the improvement of management level and scale optimization of marine science and technology activities; at regional level, regional efficiency changes can be divided into three types, accumulation-driven, application-driven, and low-growth. The main factors driving the efficiency of marine science and technology growth varies by region, however, the decrease of efficiency is mainly due to the lack of accumulation and improvement of marine scientific and technological knowledge.
