This paper presents an improved method of interpretive structural model (ISM) based on Grainger causality test, which uses objective statistical data to determine the relationship between the influencing factors, and then helps to solve the subjectivity predicament in the original model in which the expert-evaluation method is used to determine adjacency matrix. The paper also analyzes the factors influencing the coordinated development level of logistics and economy, and makes an empirical test which verifies the feasibility of the improved ISM.
