中文摘要:基于Panel Data 模型,采用中国31个省份,2005-2015年的面板数据,对信息化与物流产出的关系从静态和动态两个角度分别进行研究.面板数据模型的研究结果表明:信息化对物流产出的提高意义重大,其弹性系数为0.198.再利用向量自回归模型(PVAR)的脉冲响应函数和方差分解动态分析了不同变量冲击下物流产出的变化,结果发现信息化对物流产出的影响趋势最大且有明显的上升趋势,资金投入对物流产出呈现下降趋势,物流设施总体比较平稳.

Study on the Relationship between Informationization and Logistics Based On Panel Data
Abstract:Based on the panel data model,the panel data of 31 provinces in China from 2005 to 2015 were used to study the relationship between informationization and logistics industry from two aspects: static and dynamic.The research shows that informationization on the development of the logistics industry has a significant contribution,and the elastic coefficient is 0.198.Based on the impulse response function and variance decomposition of vector autoregressive model,the change of logistics output under the impact of different variables reveals that the influence of informatization on logistics output is the biggest and shows obvious trend,capital investment on the logistics output shows a downward trend,and the logistics facilities show the overall stability.
