The Grey correlation analysis and grey correlation model are used to study the cargo throughput of Fujian coastal port and the data of inland province gross domestic product (GDP) from 2001 to 2013. The sequence for data processing through the correlation between distribution and sort was selected, the most influential spatial distribution and coastal port economic hinterland range was calculated.Thus the conclusion was made:Fujian province should focus on Jiangxi province as the main hinterland, and cooperate with Hunan province as secondary hinterland, and then take Hubei and Anhui provinces as the third hinterland. Finally Fujian province should combine the resource advantages of hinterlands with developed regional economyThe measuring of coastal ports of Fujian province provide the theoretical basis and support for its economic development.%运用灰色系统理论，采用灰色关联分析方法和模型，以2001-2013年间福建沿海主要港口货物吞吐量和内陆省内生产总值的数据为基础，选取数列进行数据处理，通过关联性分布和排序，得到福建沿海港口经济最有影响力的腹地范围和空间分布，实证得出福建沿海港口应重点发展以江西作为主要腹地、兼考虑湖南为次要腹地、湖北和安徽其次考量的结论，最后提出立足腹地实情、结合资源优势互补的经济策略建议，为福建扩展港口经济腹地措施提供理论依据和支持。
