Figures unveiled at the 2026 China International Big Data Industry Expo in Guiyang, Guizhou province, showed that data-related software products, including AI application software, and data-resource products involving token services generated a combined 4.99 trillion yuan. The two categories accounted for 73.6 per cent of the industry’s total output, underlining the growing commercial connection between data resources and AI development.

The number of data enterprises operating across China reached 482,000 by the end of 2025, an increase of 17.9 per cent from a year earlier. The eastern regions remained the largest concentration of activity, with their data industry valued at about 5.23 trillion yuan.

Growth has accelerated steadily over the past three years. China’s data industry was valued at 5.06 trillion yuan in 2023 and 5.86 trillion yuan in 2024 before climbing above 6.7 trillion yuan last year. Expansion has increasingly shifted from basic data collection and processing towards higher-value services designed for AI models, intelligent agents and industry-specific applications.

High-quality datasets have emerged as a particularly important segment. By August 2026, more than 126,000 such datasets had been established nationwide, containing more than 1,815 petabytes of data. Their combined volume has risen by more than 89 per cent since March, reflecting rapidly expanding demand from developers training and refining AI systems.

The broader supply of digital information is also growing sharply. China generated 52.26 zettabytes of data during 2025, up 27.28 per cent from the previous year and representing roughly 27.4 per cent of global data production. Enterprises accounted for about nine-tenths of the increase, with manufacturing, transport and logistics, software and information technology services recording especially strong gains.

That expansion is occurring alongside rapid growth in AI itself. China’s core AI industry exceeded 1.2 trillion yuan in 2025, with more than 6,200 specialised AI enterprises operating nationwide. More than 30 per cent of large manufacturing enterprises had adopted AI technologies by the end of the year, widening demand for industrial datasets capable of training systems for production, quality inspection, predictive maintenance and automation.

AI development is also changing the composition of the data market. Large language models initially depended heavily on publicly accessible text and image material, but developers are increasingly seeking proprietary industrial, scientific, financial, medical and operational data. The expansion of intelligent agents and embodied AI is adding demand for video, three-dimensional information, sensor readings, physical interaction records and synthetic data.

Intelligent-agent innovation has become another growth area. More than 3,400 patents associated with agent technologies were authorised during 2025, with the pace of growth more than doubling from the previous year. Commercial platforms are simultaneously combining access to multiple AI models with tools that allow companies to select, adapt and deploy systems without developing every component internally.

Policy is increasingly focused on turning China’s vast quantity of information into commercially usable AI resources. A national programme launched this year calls for high-quality industry datasets covering areas including scientific research, manufacturing, agriculture, energy, transport, financial services, healthcare, education, e-commerce, tourism, meteorology, urban governance, autonomous driving, embodied intelligence and biotechnology.

The programme is intended to expand dataset supply, improve annotation and quality assessment, encourage controlled circulation and connect dataset development more closely with practical AI applications. Authorities are targeting significant progress by the end of 2028, including industry datasets tested through real-world applications and specialised companies capable of developing tools and standards around them.
