Abstract: Driving the deep integration of the digital economy and the real economy is a core issue in constructing a modern industrial system. The mining industry, as a traditional foundational sector, with its digital transformation provides a typical scenario for investigating the coupling coordination mechanism between the digital and real economies. However, systematic quantitative research on its pathways and regional heterogeneity remains insufficient. This paper aims to analyze the internal mechanism and regional heterogeneity of mining digitalization in driving the integration of the digital and real economies. Based on three core dimensions: technological enablement, data-driven processes, and institutional adaptation: a comprehensive indicator system is constructed to evaluate the development levels of both economies. Utilizing panel data from seven Chinese provinces or cities （Beijing, Tianjin, Shanghai, Jiangsu, Zhejiang, Anhui, Henan） from 2013 to 2022, the entropy weight method is employed to objectively determine indicator weights and calculate comprehensive development indices for the subsystems. A coupling coordination degree model is applied to accurately measure the integration level and dynamic evolution trends between the two major economic systems. The empirical results indicate that during the study period, the development of mining digitalization significantly promoted the integration process, with the coupling coordination degree of all provinces showing a steady upward trend, albeit with significant regional disparities. Specifically, eastern coastal regions （e.g., Jiangsu, Zhejiang）, leveraging strong technological accumulation and industrial foundations, achieve high-level coordinated integration. Central regions （e.g., Anhui, Henan）, relying on resource endowments and policy follow-up, demonstrate steady catch-up trends. Some municipalities （e.g., Tianjin）, although starting from a lower base, exhibit noticeable growth rates, indicating significant potential. Further mechanism analysis reveals that the effective synergy of the three-dimensional driving mechanism （“technology-data-institution”） is key to promoting integrated development, and its intensity and manifestation exhibit distinct regional adaptability characteristics. Based on these findings, the study proposes regionally differentiated strategies: in technologically advanced eastern regions, focus on building digital technology trading and conversion platforms to accelerate technology spillover; nationwide actively explore federated data sharing models and resource data assetization paths to break down data silos; simultaneously, establish a cross-regional flexible mobility mechanism for digital talent to provide sustainable systemic momentum for the deep integration of the digital and real economies across the country.
