Abstract: With the continuous breakthroughs and development in transportation technology， transportation modernization has increasingly become a key driving force for promoting the process of Chinese style modernization. Utilizing panel data from 30 provinces spanning the years 2014 to 2022 as our research samples， this paper empirically examines the relationship between transportation modernization and Chinese style modernization. The analysis is conducted by measuring the respective levels of both concepts and employing various models. The results show that transportation modernization can significantly enhance the level of Chinese style modernization， and the conclusion remains valid after robustness tests. In terms of mechanisms， innovation capability and industrial structure upgrading are two important channels for transportation modernization to empower Chinese style modernization. In terms of regional heterogeneity， the positive impact of transportation modernization on the level of Chinese style modernization is stronger in the eastern region compared with the central and western regions. Furthermore， the analysis of spatial spillover effects reveals that transportation modernization not only enhances the modernization level within a given region but also significantly contributes to the modernization of neighboring areas.

Key words: transportation modernization, Chinese style modernization, regional heterogeneity, spatial spillover effect
