The new-generation information technology industry is a strategic, foundational, and pioneering sector of the national economy, serving as a crucial pillar for building a strong manufacturing nation and achieving high-quality development. Based on comprehensive data, this study reviews the overall progress and achievements of China's new-generation information technology industry from 2015 to 2025, focusing on four dimensions: industrial scale, industrial structure, innovation capacity, and integrated application. Meanwhile, aligning with the key development areas identified in the national strategy for strengthening the manufacturing sector, the study offers a detailed analysis of China's concrete practices in accelerating the development of the new-generation information technology industry through application-driven approaches and industrial collaboration. Special attention is given to addressing shortcomings such as insufficient self-sufficiency in core components, lagging processes of advanced integrated circuits, and dependence on foreign high-end software. Looking ahead to the next decade, China's new-generation information technology industry will center on supporting new-type industrialization, focusing on four key directions: innovation leadership, supply chain resilience, comprehensive penetration, and open cooperation. Through major strategic initiatives and multi-pronged measures, efforts will be made to achieve breakthroughs in cutting-edge technologies such as 6G, artificial intelligence, and quantum information; overcome critical constraints in high-end chips, core software, and key equipment; accelerate the widespread integration of new-generation information technologies across all sectors of the economy and society; and deepen the convergence of the digital and real economies, thereby providing robust momentum for Chinese modernization.
