China uses big data to connect public services, transport, finance, healthcare, agriculture, commerce and environmental systems. Government reports show large-scale digital infrastructure and online services already in operation; a national action plan also sets out capabilities it aims to promote, which should not be mistaken for proof that every proposed system is deployed everywhere.
What “big data” means in China’s case
Here, big data is not one database or consumer product. It refers to the collection and analysis of information from many sources—such as government records, transport networks, payments, utilities, health services and connected devices—to support decisions or coordinate services. Some applications are reported as current outputs; others are policy goals described in a national action plan.
The scale indicators in the National Data Administration’s 2024 and 2025 reports help explain why the subject is treated as infrastructure. The figures below are government-reported national totals, not measures of the data actually used by any one service.
| Indicator | Reported figure | Source and period |
|---|---|---|
| Data production | 32.85 ZB | National Data Administration, 2024 report, reporting 2023 |
| Data production | 41.06 ZB, up 25% year over year | National Data Administration, 2025 report, reporting 2024 |
| Computing capacity | 230 EFLOPS | National Data Administration, 2024 report, reporting 2023 |
| Computing capacity | 280 EFLOPS | National Data Administration, 2025 report, reporting 2024 |
| 5G base stations | 4.251 million | National Data Administration, 2025 report, reporting 2024 |
| Internet users | 1.092 billion | Government of China, 2024 report, reporting 2023 |
| Cellular-IoT terminals | 2.332 billion | Government of China, 2024 report, reporting 2023 |
ZB means zettabytes; EFLOPS is a measure of computing operations per second. The reported growth in data and computing capacity is evidence of expanding infrastructure, not by itself evidence that a particular application is effective or that every data source can be freely combined.

How big data is used in government services
Digital-government systems bring administrative information together so people and businesses can apply for services online and, in some cases, across jurisdictional boundaries. The National Data Administration’s 2024 report says 92.5% of provincial administrative-licensing matters were accepted online in 2023. “Accepted online” describes the application channel; it does not mean every procedure was completed instantly or without further checks.
The Administration’s 2025 report lists 21 “high-efficiency” cross-government service items. It also reports remote medical services covering all cities and counties. These are reported national service outputs; they do not establish identical service quality, access or processing times in every locality.
How data supports smart-city management
A national action plan describes bringing together information about people, land, events, objects, conditions and organizations. Its aim is to give city agencies a more current picture of conditions and help them assess risks and coordinate responses. The plan names traffic management, public health, public security and ecological protection among the areas where this could be applied.
It also points to services that cross city boundaries, including business registration, medical-expense settlement and pension portability. These are policy directions rather than a guarantee that all cities already offer every service through interoperable systems. In practice, the plan’s goals depend on agencies being able to share compatible data and act on it in time.

How big data is used in transport and logistics
The plan proposes connecting transport and logistics information that is often spread across different operators and systems. Sources it names include freight, waybills, settlements, insurance, tracking, road infrastructure, traffic flows and driving behavior. The intended uses include:
- Route planning informed by traffic, road and logistics conditions.
- Electronic bills of lading and more connected freight processes.
- Intelligent port security and coordination.
- Dynamic vehicle data for safety measures, insurance and differentiated credit.
- Commercial self-driving-car pilots in defined areas and periods.
Those examples describe the plan’s targets; they do not show that each capability is available nationwide. In particular, the reference to autonomous vehicles is bounded to pilot commercial operation in specified places and time periods, not unrestricted deployment.
How finance and insurance use data
The action plan encourages financial institutions to draw on data from sectors including tax, commerce, consumption, healthcare, social security, agriculture, utilities, science, industry and weather. Its proposed applications span several stages of financial services:
- Identity and business checks: combining records to improve identification of people or entities.
- Credit and insurance design: using relevant cross-sector indicators in credit assessment or product design.
- Underwriting and claims: supporting risk assessment and processing with information beyond a single application or claim.
- Fraud and money-laundering controls: using data analysis to flag suspicious patterns.
- Risk warnings: identifying potential risks earlier for institutions and regulators.
The plan states intended functions, not the precise data fields any lender or insurer uses in an individual decision. It also does not establish that every institution has access to every listed source. For consumers, the important distinction is that more data may help assess risk but can also make it harder to understand which records influenced a decision; the cited policy material does not quantify either outcome.
How data is used in healthcare and public health
Healthcare applications in the action plan cover clinical coordination as well as administration. Proposed measures include sharing electronic medical records, mutual recognition of examination and test results among medical institutions, easier insurance claims, and links between basic and commercial health-insurance information.
The plan also proposes personal health records and connections between healthcare services and disease-control systems. For public health, it names occupational-disease monitoring and early warning of public-health incidents. These are intended uses: the plan does not demonstrate that records are interoperable across every provider or that every patient’s information is available across institutions.
How data supports agriculture and food supply
The plan calls for information about production capacity, transport, processing, trade and consumption for products such as grain, hogs, fruit and vegetables. Combining those signals is intended to improve monitoring and early warning when production or supply is disrupted.
The specific risks named include natural disasters, epidemics and price fluctuations. The practical aim is to give decision-makers a wider view of supply conditions, rather than relying only on a single stage such as farm output or retail prices. The plan does not provide a measured estimate of how much these systems reduce losses or price volatility.

How data is used for the environment, energy and climate
The action plan proposes linking meteorological, water, transport and electric-power information. It identifies hydrological forecasting, disaster analysis, pollution response, water-environment management and energy scheduling as use cases. It also includes measuring carbon footprints.
These applications depend on combining observations from different systems: for example, weather and water information can inform flood analysis, while power data can support energy management. The plan establishes these as policy objectives, not as independently assessed results or proof of uniform implementation.

The plan proposes connecting order demand, logistics, production capacity, supply-chain information, transactions, payments and population distribution. The stated goals include faster responses to market demand, more targeted promotion, supply-chain finance and cross-border e-commerce.
The National Data Administration’s 2024 Digital China report says China remained the world’s largest online-retail market for 11 consecutive years and reports 2.38 trillion yuan in cross-border e-commerce imports and exports. Those are report-level market indicators; they do not isolate how much activity was caused by big-data systems.

Is China’s social-credit system one big-data product?
No single product represents the broad data uses described here, and “social credit” should not be treated as one nationwide consumer score or database on the basis of these reports. The government reports and policy plan covered above describe data infrastructure and sector applications; they do not establish that all information is combined into one system or that a single score governs access to services, credit or travel.
They also do not provide a full account of the rules, implementation or consequences of every system sometimes labeled “social credit.” The careful conclusion is narrower: China’s documented data strategy includes cross-sector collection and use, while these sources do not prove a unified all-purpose scoring product.
What these examples do—and do not—show
The National Data Administration reports and the action plan are Chinese government sources. They document reported infrastructure and service outputs, alongside intended capabilities. They are not independent evaluations of every local implementation and do not quantify privacy harms. A plan’s use of phrases such as “will promote” describes a policy direction, not proof that all localities have deployed the capability.
