We established a grey relation degree model as well as a harmonious and coupling degree model of the interaction between regional logistics and regional economy based on the grey relational analysis method ,and quantitatively reveals the main factors which effect the coupling of regional logistics and regional economic system in Shandong Province. The coupled degrees of change from the perspective of time series were analyzed ,and the phase characteristics of interaction between the regional logistics and regional economic of Shandong Province in recent years were revealed. Study results showed that the impact of regional logistics on economic growth in the province is mainly in terms of volume instead of quality. Although on the whole,local logistics in this province coordinated with the regional economic closely,there is an obvious volatility. The results also showed that the logistics industry in Shandong Province is on the way to an ordered state of growing and maturing.%运用灰色关联分析法构建出区域物流与区域经济交互作用的关联度模型和耦合度模型，定量揭示出山东省区域物流与区域经济系统耦合的主要因素，并从时序角度分析了耦合度的变化，并揭示出山东省近年来区域物流与区域经济作用的阶段特性。研究结果表明，山东省区域物流对经济增长的影响主要表现在量的方面，而缺乏质的方面挖掘。虽然从整体上来说，山东省区域物流与区域经济交互耦合比较紧密、协调。但物流与经济耦合度存在明显的波动性，山东省的物流产业正逐步进入成长和成熟的有序状态。
