Abstract: Against the background that global trade policy shocks are reshaping the pattern of China's domestic supply chains, this study takes "the US imposing tariffs on Chinese products" as an external shock, combines monthly matching data of Chinese enterprise supply chain data and industrial and commercial registration databases, analyzes the impact and mechanism of trade policy shocks on domestic supply chain networks, and explores the path of the unified national market to optimize domestic supply chains.

The study reveals empirically that when trade policy uncertainty rises, the timely adjustment of supply chain networks and the construction of domestic market integration are crucial to enhancing industrial chain resilience. It can provide policy references for China to coordinate development and security in a complex international environment and build an independent and controllable modern industrial system.
