新冠肺炎对浙江省各类运输方式货运量的影响

The Influence of COVID-19 on the Freight Volume of Various Modes of Transportation in Zhejiang Province

新冠肺炎对交通运输行业造成了较大冲击。为了研究分析疫情对各类交通运输方式货运量的影响,本文以浙江省为研究对象,收集整理了浙江省新冠肺炎确诊患者数量和各类交通运输方式货运量的月度数据,并通过数据处理和相关模型拟合,得到新冠肺炎确诊患者数量与各类交通运输方式货运量之间的相关性和最优拟合模型,结果表明:铁路货运量受新冠肺炎确诊数量影响最弱,当新冠肺炎确诊数量较少时水路货运量受影响程度最强,当新冠肺炎确诊数量较多时民航货邮出港量受影响程度最强,当新冠肺炎确诊数量非常多时公路货运量受影响最强。

COVID-19 has caused a great impact on the transportation industry.In order to study and analyze the impact of the COVID-19 on the freight volume of various modes of transportation,this paper took Zhejiang Province as the research object,collected the monthly data of the number of confirmed patients with COVID-19 and the freight volume of various modes of transportation in Zhejiang Province,and obtained the correlation and optimal fitting models between the number of confirmed patients with COVID-19 and the freight volume of various modes of transportation through data processing and relevant model fitting.The results show that the railway freight volume is the weakest affected by the number of confirmed cases of COVID-19.When the number of confirmed cases of COVID-19 is small,the waterway freight volume is the strongest affected.When the number of confirmed cases of COVID-19 is large,the outbound volume of aviation is the strongest affected,When the number of confirmed cases of COVID-19 is very large,the road freight volume is the strongest affected.
