文章运用生态位态势理论和生态位重叠理论构建京津冀港口群竞合关系判断框架,建立港口生态位测评体系,通过实证分析对各港口之间的生态位重叠值进行测评。根据实证结果制定科学合理的京津冀各港口竞合策略以调整港口竞合关系,从而实现对京津冀区域港口资源要素的整合规划。 The article uses the theory of niche potential and niche overlap theory to construct the judgment framework of the co-opetitive relationship between ports in Beijing, Tianjin and Hebei, and establishes the evaluation system of port niche. Through the empirical analysis, the niche overlap between ports is evaluated. According to the empirical results, draw up a scientific and rational strategy for competing and competing with other ports in Beijing, Tianjin and Hebei to adjust the competition and cooperation in ports so as to realize the integrated planning of the resource elements in the port area of ​​Beijing, Tianjin and Hebei.
