Abstract Utilizing data from Chinese industrial enterprises and China Customs’ import and export data spanning from 2000 to 2014, this paper adopts a nationwide unified market perspective and introduces market accessibility as a novel metric for transportation infrastructure networks. It investigates the impact of transportation infrastructure networks on the quality of export products and explores the underlying micro-mechanisms. The study shows that the construction of transportation infrastructure networks significantly enhances the quality of export products. A series of robustness tests confirm that the conclusion remains valid. Mechanism tests reveal that the construction of transportation infrastructure networks promotes the upgrading of export product quality through demand-driven effects, talent mobility effects and technological innovation effects. Heterogeneity analysis indicates that the construction of transportation infrastructure networks is more conducive to enhancing the export product quality of state-owned and foreign-invested enterprises, differentiated products, technology-intensive and capital-intensive enterprises, as well as exports to OECD countries. Extended analysis demonstrates that the nationwide unified large market further intensifies the enhancing effect of transportation infrastructure network construction on the quality of export products. The research provides a theoretical framework and empirical evidence on how transportation infrastructure networks can drive international circulation through domestic circulation, thereby achieving a high level of openness to the outside world.
