The present study investigates the transformative impact of the Fourth Industrial Revolution, encapsulated in the "Industry 4.0" framework, on the socio-economic systems of G7 countries, Russia, Kazakhstan, and Uzbekistan, drawing on contemporary scientific evidence. It explores how the integration of digital technologies—such as Big Data, the Internet of Things (IoT), and cyber-physical systems—reshapes industrial production, enhances resource efficiency, and fosters sustainable development, while simultaneously posing social and institutional challenges. The research employs a systemic analysis and comparative approach, highlighting the differential adoption of smart technologies like Smart Grid in Russia and IoT-driven agricultural advancements in Uzbekistan, alongside G7 leadership in automation. Findings reveal that while Industry 4.0 drives economic growth and environmental benefits, it also exacerbates labor market disruptions and resource demands, necessitating robust institutional reforms and a "Just Transition" framework. This comparative analysis underscores the need for tailored strategies to balance technological progress with social equity across diverse economic contexts.
