本文利用单位根检验、协整检验和格兰杰检验对中国物流行业C排放与货运量增量两组时间序列进行平稳性、均衡关系和格兰杰原因的验证,并运用线性回归的方法对两组变量的关联程度进行分析。结果显示1随着经济的发展中国物流行业发展迅猛(以递增的货运量增量为代表),另一方面物流行业排放的C亦逐年增加,货运量增量与行业C排放水平呈较强的正相关关系。2物流行业C排放是货运量增量的Granger原因,计算行业C排放水平可以有效预测货运量增量大小。3在其他条件不变的情况下C排放每增加(或减少)1个单位则货运量增量相应增加或减少37.412个单位,二者之间有较强的互动性。
In this paper, the unit root test, cointegration test and Granger test are used to verify the stability and equilibrium of two time series of C emissions and freight volume increment in China’s logistics industry and Granger’s reasoning. The linear regression method The correlation between the two groups of variables was analyzed. The results show that with the economic development of China’s rapid development of the logistics industry (represented by incremental freight volume increases), on the other hand, the C emissions of the logistics industry also increased year by year, freight volume increases and industry C emission levels were strong Positive relationship. 2 C Logistics in the logistics industry is the Granger cause of freight volume increment. Calculation of industry C emission level can effectively predict the increment of cargo volume. 3 For every additional C increase (or decrease) in other conditions unchanged, a corresponding increase or decrease of 37.412 units in freight volume increase with strong interaction between the two.
