中文摘要：

从资源、产业、科技与环境4个角度，构建海陆一体化评价指标体系，通过能力结构关系模型与层次分析法，定量评价环渤海地区海陆一体化程度。计算结果表明：天津市和山东省的科技支持能力较强，海陆经济发展以科技带动为主，河北省和辽宁省的资源利用能力较高，海陆经济发展以资源型产业为主导产业。天津市和山东省的海陆经济属于高程度耦合、高层次的海陆一体化；河北省和辽宁省的海陆经济属于低程度耦合、低层次的海陆一体化。通过分析天津市、河北省、辽宁省和山东省自身的海陆经济发展情况，提出加强各地区海陆经济合作和整个环渤海地区区域间合作的建议。

The results show that： as for marine and land economy development pattern, Tianjin City and Shandong Province are the technology-driving type, while Liaoning Province and Hebei Povince are the resources-driving type. Finally, some suggestions for the inten- sive and extensive integration of sea ＆ land economy in Bohai Sea Ring Area are put forward.
