摘要
区域物流与区域经济发展之间存在着密切的关系。通过计算我国物流业与经济发展有关指标的相关系数和灰色关联度,对两个系统的相关性进行了定量分析,同时也进行了Granger因果检验,并应用多维灰色动态协调模型GM(1,N)来定量测度两个系统之间的协调性。研究结果显示:我国物流业与经济发展之间存在着高度的相关性,两者相互依存、相互促进,而物流业的发展不能适应经济发展的需要。
In this paper, through calculating the relevant coefficients and grey correlativity of the development of the logistics industry and economy of China, we quantitatively analyzed the correlation between the two systems, subjected it to the Granger causal test and applied the multi-dimensional grey dynamic coordination model to measure the level of coordination between the two. The result indicated that the two were highly correlated, interdependent and mutually promotive, yet the development of the logistics industry could not satisfy the demand of the economy.
