Abstract: This paper starts from the connotation of international dry port competitiveness, and based on high-frequency indicators in corporate competitiveness and dry port management, combined with relevant literature, it selects corresponding indicators to evaluate the competitiveness of international dry ports from four aspects: internal infrastructure of the dry port, level of logistics development, level of commercial and trade development, and the external level of regional economic development. The indicators are initially screened based on the principle of observability, and then quantitatively selected through a combination of correlation and principal component analysis, thus constructing an evaluation system for the competitiveness of international dry ports.
