基于环渤海港口经济“门户”功能战略视角，从环渤海港口群主要港口生产性指标出发，构建强度模型并引入港口变量，对环渤海港口群的辐射能力强度和有效性进行测度和实证分析。研究结果表明：①环渤海港口群在全国五大港口群中辐射强度中等。环渤海形成以青岛港、天津港和大连港为轴心的“弓形”陆向港口辐射系统。②环渤海港口群辐射力有效度弱：环渤海港口群整体K值为1.01，属于“极低贡献度”港口群。环渤海港口群之间Rij值在[50,100）之间，属于“中低度密切联系”港口群。③环渤海港口群系统内部发展水平存在明显的区域分异：环渤海南部港口群辐射力强于北部，南部港口群之间的空间密切联系程度高于北部，南部港口群系统内部资源使用的协调性和有效性优于北部。

Based on strategic perspective of Bohai Bay port economy "portal" function and Bohai Bay port production index, an Intensity Model was established with the introduction of port variablesto empirically research on Bohai Bay regional radiation availability and utility. The empirical result shows:①Area of Bohai Bay ports overall radiation intensity is in the middle level compared with domestic five big port group. Bohai Bay is formed in Qingdao port, Tianjin port and Dalian Port as the axis of the "arch" terrestrial port radiation system.②The availabilityof Bohai port group is weak: the overall K value is 1.01, which belongs to the "low contribution" port group. Bohai port groupRij=[50,100), whichbelongs to the "low level contact".③Within Port group the development level of Bohai have clear regional divergence: The southern Bohai port group has stronger radiation than the north of Bohai port group; the spatial contact within the south of Bohai port group is closer than that of northern Bohai; the coordination and utility of the southern Bohai port internal resources is better than that of northern Bohai.
