China Is Setting the Standard for the Connected Cities

For years, the smart city was sold as a dream, the kind of thing that lived comfortably in sci-fi movies and cartoons: everything linked, everything visible, everything run from one glowing wall of tv’s. What once looked like fantasy now looks more like procurement than fiction. By 2024, 70.9% of people in the EU were already using at least one internet-connected device.

Long before most people noticed the shift, parts of that logic had already become ordinary. Traffic lights were coordinated. Smart grids were. Airports had become dense operational environments where sensors and software quietly manage waste, parking, cleaning, and passenger flow. Global air traffic reached 9.4 billion passengers in 2024, and Atlanta alone handled more than 108 million. That kind of scale does not work without digital coordination. The airport is not a metaphor for the smart city so much as its smaller working prototype.

As the same logic moved into domestic life, connectivity began to feel less futuristic and more routine. We connected our TVs, thermostats, speakers, lights, appliances, and security tools until the connected home stopped feeling novel. The average U.S. internet household had 7 connected devices in 2023. The move from homes to urban infrastructure no longer feels speculative. It feels like scale.

That broader shift is the real backdrop to China’s current push. Beijing is not simply building smarter cities at home. It is positioning Chinese technologies, platforms, and protocols to shape how future urban infrastructure is built elsewhere. Its policy targets make the ambition plain: more than 50 standards and 10 billion IoT terminal connections by 2028.

From Smart Tools to Citywide Coordination

What defined the first wave of “smart” technology was improvement without full coordination. In homes, that meant app-controlled lighting, thermostats, and security. In cities, it meant better monitoring of traffic lights, water networks, and sewage. But those tools were usually procured separately and rarely built to work as one coordinated environment. Even in 2024, only 14.2% of people were using internet-connected home energy systems and 11.8% were using smart home security devices. The pattern was still partial adoption, not full orchestration.

What matters now is the next step.

Across cities, traffic, utilities, buildings, logistics, emergency response, and public administration are increasingly being treated as parts of one urban operating environment rather than as separate domains to be upgraded one by one. The point is no longer just to connect more devices. It is to make city functions legible to one another. More than 56% of the world’s population already lives in cities, and that share is projected to approach 70% by 2050.

From a policy and operational standpoint, the appeal is easy to understand. Better coordination can reduce waste, smooth commutes, lower costs, and improve service delivery. It can shave minutes from response times, reduce peak-load pressure, and route sanitation or traffic operations more efficiently. Cities already generate more than 80% of global GDP.

What separates the integrated city from earlier talk of smart grids, smart buildings, or connected transit is not sophistication alone, but convergence. Those tools may be advanced, yet they often stay in their own lanes. A city begins to change when those lanes start to merge: when transport data informs emergency response, when energy systems coordinate with buildings, and when sanitation, traffic, and public safety feed into the same operational picture. The environmental stakes are just as large. Cities consume between 75% and 78% of the world’s energy and produce more than 60% of greenhouse gas emissions.

Research increasingly reflects that same shift in emphasis. Smart-city development is now framed less as a matter of adding devices and more as a matter of aligning energy, transport, and digital functions across sectors. The important change is not simply that more things are online. It is that they are beginning to operate inside a shared logic. Cross-domain alignment now sits near the center of smart-city maturity.

China’s Edge Is Scale, Deployment, and Standards

Seen in that context, China’s position carries more weight than a standard urban-modernization story suggests. Many governments want smart cities. China is trying to shape the rules under which they operate. Its 2024 urban digital transformation guideline pushes development across planning, construction, management, service, and operation, while the broader IoT action plan sets targets for more than 50 standards and 10 billion terminal connections by 2028. At home, that looks like modernization. Internationally, it looks like an attempt to define the technical language of future urban infrastructure.

Because standards do not emerge in the abstract, scale matters. They are built through products, manufacturing, deployment, and repetition. China’s advantage is that it can align ministries, manufacturers, local governments, and platform builders around the same direction. By 2024, the country had built more than 4 million 5G base stations and accounted for roughly 60% of the global total.

Scale matters.

Once cities rely on large numbers of machines exchanging information, communications protocols, data formats, security frameworks, and interface rules all become more consequential. China already had more than 1 billion 5G connections by the end of 2024, and adoption is projected to reach 88% by 2030. China is not only building domestic capacity. It is creating a live proving ground for tools and rules that may travel later.

Looking Beyond China

What makes this important is that the value in urban technology is shifting away from the device itself and toward the layer that makes devices work together. That layer shapes procurement, compatibility, maintenance, and long-term dependence. Public-sector spending on data analytics continues to rise because the real leverage increasingly sits in interpretation, coordination, and control rather than in hardware alone.

Although the economic case is straightforward, the larger issue is geopolitical. Cities concentrate people, logistics, energy demand, and public services, and the pressure to manage them more efficiently will only rise. But if one country’s firms help define the rules through which urban infrastructure communicates, influence extends far beyond exports. It reaches into vendor compatibility, data formatting, platform dependence, and long-term control. That is why the standards target matters.

As urban functions begin to share more information, data sovereignty follows quickly. In an integrated city, transportation data can feed public safety, building data can shape energy use, and utility data can affect emergency management. Once those streams merge, ownership, storage, access, and governance become harder to separate. Interoperability quickly stops being a narrow engineering question and becomes a legal, institutional, and political one.

Governance changes with it. A city that can see more can manage more. It can also centralize visibility, deepen surveillance, and increase dependence on technical systems few citizens fully understand.

The politics sit underneath the efficiency.

That is why connected urban infrastructure cannot be treated as a neutral upgrade. It is also a choice about dependence, authority, and control.

The Contest Over Urban Infrastructure

As the smart city moves out of the realm of concept and into the realm of infrastructure, procurement and governance move with it. Cities will increasingly have to ask not only what tools to buy, but what system they are joining. In a world moving toward 5.5 billion 5G connections by 2030, that question will only become more pressing.

For that reason, China’s push deserves attention well beyond China itself. The contest over smart cities is hardening into a contest over the rules of urban connectivity. The countries and companies that define those rules will not simply influence products. They will influence the structure of urban life. China’s own targets, 10 billion IoT terminal connections and more than 50 standards by 2028, make that ambition unusually explicit.

Cities will keep growing. Infrastructure will keep digitizing. The unresolved question is not whether urban life will become more networked, but whose rules, values, and technical assumptions will govern that shift. In that sense, the future of the smart city may be decided less by the city itself than by whoever succeeds in setting the standard.

Key takeaways

• • The smart city has moved from isolated digital upgrades to cross-system urban coordination.
  • The strategic value now sits less in devices than in platforms, protocols, and standards.
  • China’s domestic rollout is also a bid to shape how connected urban infrastructure is built elsewhere.
  • As cities become more interoperable, procurement choices start to carry long-term governance consequences.
  • The deeper contest is no longer just over smart tools, but over who sets the operating rules.
  • Connected-city competition is becoming a market-structure contest, not just a technology race.
  • Smart grids are central because coordination fails without an intelligent energy backbone.
  • Interoperability is now a strategic issue because it shapes compatibility, lock-in, and long-term control.
  • Data governance matters more as urban systems begin to share information across agencies and vendors.
  • Domestic scale can become global influence when deployment, platforms, and standards move together.
