How Does Trade Policy Uncertainty Affect Supply Chain Efficiency: A Case Study of Listed Companies of Chinese Port Industry

Abstract

This paper uses a data sample from listed companies in the national port industry from 2007 to 2020 to systematically explore the impact of trade policy uncertainty on the supply chain efficiency of listed companies in the national port industry and its mechanism based on the events of Sino–US trade policy changes. It is found that the increase in trade policy uncertainty significantly reduces the enterprises’ supply chain efficiency. The further influence channel test shows that the increase of trade policy uncertainty inhibits the improvement of enterprises’ supply chain efficiency by reducing the export quantity and technological innovation channel of enterprises. From the perspective of trade policy changes, this paper provides a new explanation for understanding the dynamic changes in the supply chain efficiency of Chinese enterprises in recent years and enriches relevant research on evaluating the economic effects of trade policy uncertainty.

Examining the Contribution of Logistics and Supply Chain in Boosting Oman’s Trade Network

“…A trade policy's effects would spread throughout the world's supply chain network and have an impact on numerous supply chain participants. Lin et al (2023) discovered that increased Sino-US trade policy uncertainty dramatically decreased corporate supply chain efficiency. Therefore, increased trade policy uncertainty can dramatically lower the performance of an enterprise's supply chain.…”

“…In another dimension, the global trade expansion has been strongly driven by regional dynamics involving proliferation in regional trade agreements (Esteve-Pérez et al 2020). Trade policies also affect global supply chain networks, altering product flows (Lin et al 2023;Chen et al 2023;Feng et al 2022). According to trade network linkages, intermediate inputs are more important if their suppliers are more concentrated, and industrial chains containing several key intermediate inputs tend to be more complex than those in other sectors (Cui et al 2023).…”
