How to Utilize New Technologies to Improve Productivity:

This study investigates the transformative role of digital technologies in driving structural economic change across manufacturing, services, and agriculture in emerging markets, with China as a central case. Using a mixed-methods approach that combines empirical sectoral data, policy analysis, and comparative case studies, the research uncovers how artificial intelligence (AI), the Internet of Things (IoT), and platform economies contribute to productivity gains, labor market restructuring, and inter-sectoral synergies. Findings reveal that while digitalization enhances competitiveness in manufacturing and enables service-sector expansion through fintech and e-commerce, agriculture remains digitally marginalized due to infrastructural and institutional deficits. The paper highlights how policy asymmetries, digital literacy gaps, and regional inequalities deepen digital divides, impeding inclusive development. A conceptual framework is developed to illustrate how digital infrastructure and institutional support mediate sectoral transformation.
