This study explores the relationships among Industry 4.0 technologies, their application areas,and the involvement of Russian manufacturing firms in global and domestic value chains. Weapply logit and multinomial logit regressions using an original survey dataset of approximately1700 Russian manufacturing firms. We make a novel contribution to the literature by uncoveringan asymmetry in adopting Industry 4.0 technologies among Russian industrial firms in domesticvalue chains (DVCs) and global value chains (GVCs). This asymmetry has the potential to impedeGVC localization and DVC internationalization. Based on our results, software automation solu-tions are the only ones demonstrating statistical significance for firms participating simulta-neously in GVCs, DVCs, and both GVCs and DVCs. Companies in DVCs demonstrate a broaderutilization of Industry 4.0 technologies across various application areas. We also identify evidenceof reshoring in DVCs, indicating that Industry 4.0 adoption encourages firms to establish enduringrelationships with domestic suppliers. Highlighting that differences in technology adoption areinfluenced by external factors, including adherence to international standards and regulatoryprinciples, we propose policy implications for developing countries. Recommendations encom-pass reducing entry barriers to DVCs, improving procurement transparency, and promotingcompetition in the digital solutions market to empower firms for seamless GVC integration.
