Abstract: Based on panel data from 2014 to 2023 for Yibin, Luzhou, Neijiang, and Zigong in the Southern Sichuan region, this study constructs a comprehensive evaluation system encompassing five dimensions of the digital economy (infrastructure, industrial development, innovation potential, service development, and livelihood integration) and six dimensions of new-type urbanization (economy, population, society, ecological environment, land use, and livelihood). The entropy method is employed to measure the development levels of the digital economy and new-type urbanization, and a coupling coordination model is applied to empirically assess their coupling coordination degree. Key findings include: Both the digital economy and new-type urbanization in Southern Sichuan exhibit steady growth, though the digital economy lags slightly behind urbanization, with a narrow gap between the two. No significant polarization or developmental disparities exist among the cities in terms of digital economy and urbanization levels. The coupling coordination degree between the digital economy and urbanization shows an upward trend. During the initial study period, all cities experienced imbalanced coordination, but rapid advancements in both systems led to substantial improvements in coordination during the mid-to-late stages.
