根据系统动力学原理和方法，从区域物流供需耦合系统特征和系统要素因果关系出发，建立耦合系统的SD模型，并以该模型仿真模拟了天津市物流供给、需求和环境之间相互影响的动态机制，据此对区域物流供需比、物流业经济贡献率和就业贡献率等参数进行分析，为促进区域物流与经济协同发展提供理论参考。
根據繫統動力學原理和方法，從區域物流供需耦閤繫統特徵和繫統要素因果關繫齣髮，建立耦閤繫統的SD模型，併以該模型倣真模擬瞭天津市物流供給、需求和環境之間相互影響的動態機製，據此對區域物流供需比、物流業經濟貢獻率和就業貢獻率等參數進行分析，為促進區域物流與經濟協同髮展提供理論參攷。

In this paper, using the principle and method of the system dynamics theory, and starting from the characteristics of the regional logistics supply-demand coupling system and the causal relationship of the system factors, we built the SD model of the coupling system, then used the model to simulate the dynamic mechanism of the mutual influence of the logistics supply, demand and environment in Tianjin and then analyzed the parameters such as the supply-demand ratio of regional logistics, contribution of the logistics industry to economic growth and to employment, etc.
