摘要
为分析港口物流和对外贸易之间的关系,文章选取1990—2020年广西港口货物吞吐量和外贸进出口总额作为评价指标,通过建立VAR模型,运用ADF检验、协整检验、脉冲响应以及方差分解等方法对广西港口物流和对外贸易之间的关系进行实证分析。分析结果显示,长期看广西港口物流与对外贸易存在着相互促进的协整关系,广西港口物流对对外贸易的推动作用明显,广西对外贸易对港口物流的推动作用并不明显。
To analyze the relationship between port logistics and foreign trade,the article selects the cargo throughput and total import and export volume of Guangxi ports from 1990 to 2020 as evaluation indicators.By establishing a VAR model,the article empirically analyzes the relationship between port logistics and foreign trade in Guangxi using methods such as ADF test,cointegration test,impulse response,and variance decomposition.The analysis results show that in the long run,there is a mutually promoting cointegration relationship between port logistics and foreign trade in Guangxi.The role of port logistics in promoting foreign trade in Guangxi is obvious,while the role of foreign trade in promoting port logistics in Guangxi is not significant.
