基于多元线性回归模型的物流领域标准实施效益评价

Evaluation of Standards Implementation Benefit in Logistics Field Based on Multiple Linear Regression Model

以2001~2018年物流行业GDP、运输线路长度、货运量、平均就业人数、标准化水平等统计数据作为基础样本数据,建立物流领域标准实施效益分析多元线性回归模型。通过Eviews统计分析软件,对回归方程进行估计并检验,分析标准实施对物流行业经济发展的边际影响。结果表明,标准实施对物流行业经济发展具有显著的正相关关系,标准化水平每提高1个单位,GDP将增长0.03%。

Based on the statistical data of GDP,length of transportation routes,freight volume,average number of employed person and standardization level of logistics industry from 2001 to 2018 as the basic sample data,this paper establishes a multiple linear regression model for the benefit analysis of logistics standards implementation.In Eviews software,we tried to estimate and test the regression equation of the model.Then we evaluated the marginal impact of standard implementation on the economic development of logistics industry.The results show that:the implementation of standards has a significant positive correlation with the economic development of logistics industry,and the GDP will increase by 0.03%for one unit increase of standardization level.
