What are the market dynamics of smart cities industry?

Cities will be severely impacted by climate change. A survey of 1,000 cities by the Carbon Disclosure Project (CDP) found that more than 90% of the cities will face significant climate hazards that can put people and infrastructure at risk. Climate-related threats to cities include floods, severe heatwaves, and diminishing water sources. City digital twins will prove invaluable for limiting carbon emissions and simulating (and preparing for) climate disasters. Smart water metering and leakage detection technologies will become essential as water supplies diminish and urban demand grows.

Cities will need to become smart when using both existing and new technologies, such as the Internet of Things (IoT) and artificial intelligence (AI). Effective analysis of smart city data offers the prospect of automated infrastructure, where a city can use its data to benefit its people and keep them safe.  AI, for example, will help to find more efficient ways of allocating energy, improving the efficiency of water pipes, sewage, and utilities, and monitoring them to predict and reduce maintenance requirements. It can also be applied to the flow of transport and people and provide planning controls and transportation routes to reduce CO2 emissions.

What is the city-level outlook of smart cities?

The cities that have taken a leadership role in the drive to become smart are Amsterdam, Berlin, Copenhagen, Hong Kong, London, New York, Paris, Reykjavik, Singapore, Taipei, and Tokyo.

What are the key trends that will shape the smart city themes in the future?

The key trends shaping the smart city’s theme over the next 12 to 24 months can be divided into three categories: technology trends, macroeconomic trends, and regulatory trends.

Technology trends

The main technology trends that will impact the smart city theme are the metaverse, cyber threats, digital twins, AI adoption, 5G, surveillance tech, and digitalization.

Macroeconomic trends

The main macroeconomic trends that will impact the smart city theme are the post-COVID smart city, water shortages, smart city geopolitics, and the digital silk road.

Regulatory trends

The main regulatory trends that will impact the smart city theme are COP26 impact on cities and emerging tech charters.

What are the different value chains of smart cities?

The value chain of smart cities can be divided into three segments: smart city platforms, smart city apps, and smart city services.

Smart city platforms

Smart city platforms provide a platform for the unified delivery of local public services. Although each city is unique and all have its challenges around delivering services and providing vital infrastructure, a common factor is that more value will be delivered by integrating each smart city service in an all-encompassing platform. This allows for the creation of open data services to encourage innovation and the development of new digital services. It also supports the sharing of vital information to improve each constituent part of the smart city.

Smart city apps

Smart city applications can be further segmented into smart buildings, smart transport, smart infrastructure, and smart grid. Health measures in the form of improved heating, ventilation, air conditioning (HVAC), and screening systems are the crucial components of smart buildings. There cannot be a smart city without smart mobility, and smart mobility is impossible without smart transport infrastructure. The cities have also invested in two infrastructure types: health infrastructure that directly tackles the spread of COVID-19 and infrastructure that improves citizens’ digital access. Moreover, a smart grid modernizes power systems through self-healing designs, automation, remote monitoring and control, and the establishment of microgrids.

Smart city services

Cities do not have the design, technical, integration, or data analysis skills to become smart cities on their own. There is an active market for smart city design and integration services, which stitch together applications for smart buildings, transportation, infrastructure, and power grids. On the integration side, the providers of these services include large players such as IBM, Siemens, and Huawei, together with the likes of TCS, Capgemini, Wipro, and notably in Asia, Mitac.

Business Intelligence & Marketing Manager, SAL Heavy Lift

“COVID-19 has caused significant interference to our business and the COVID-19 intelligence from GlobalData has helped us reach better decisions around strategy. These two highlights have helped enormously to understand the projections into the future concerning our business units, we also utilise the project database to source new projects for Liebherr-Werk to use as an additional source to pitch for new business.”

Market Analyst & Management, Liebherr-Werk

Your daily news has saved me a lot of time and keeps me up-to-date with what is happening in the market, I like that you almost always have a link to the source origin. We also use your market data in our Strategic Business Process to support our business decisions. By having everything in one place on the Intelligence Center it has saved me a lot of time versus looking on different sources, the alert function also helps with this.

Head of Key Accounts, Saab AB

Having used several other market research companies, I find that GlobalData manages to provide that ‘difficult-to-get’ market data that others can’t, as well as very diverse and complete consumer surveys.

Marketing Intelligence Manager, Portugal Foods

Our experience with GlobalData has been very good, from the platform itself to the people. I find that the analysts and the account team have a high level of customer focus and responsiveness and therefore I can always rely on. The platform is more holistic than other providers. It is convenient and almost like a one stop shop. The pricing suite is highly competitive and value for our organisation.

I like reports that inform new segments such as the analysis on generation Z, millennials, the impact of COVID 19 to our banking customers and their new channel habits. Secondly the specialist insight on affluent sector significantly increases our understanding about this group of customers. The combination of those give us depth and breadth of the evolving market.

I’m in the business of answering and helping people make decisions so with the intelligence center I can do that, effectively and efficiently. I can share quickly key insights that answer and satisfy our country stakeholders by giving them many quality studies and primary research about competitive landscape beyond the outlook of our bank. It helps me be seen as an advisory partner and that makes a big difference. A big benefit of our subscription is that no one holds the whole data and because it allows so many people, so many different parts of our organisation have access, it enables all teams to have the same level of knowledge and decision support.

Head of Customer Insight and Research, Standard Chartered

“I know that I can always rely on Globaldata’s work when I’m searching for the right consumer and market insights. I use Globaldata insights to understand the changing market & consumer landscape and help create better taste & wellbeing solutions for our customers in food, beverage and healthcare industries.

Globaldata has the right data and the reports are of very high quality compared to your competitors. Globaldata not only has overall market sizes & consumer insights on food & beverages but also provides insights at the ingredient & flavour level. That is key for B2B companies like Givaudan. This way we understand our customers’ business and also gain insight to our unique industry”

Head of Consumer Sensory Insights, Givaudan

GlobalData provides a great range of information and reports on various sectors that is highly relevant, timely, easy to access and utilise.  The reports and data dashboards help engagement with clients; they provide valuable industry and market insights that can enrich client conversations and can help in the shaping of value propositions. Moreover, using GlobalData products has helped increase my knowledge of the finance sector, the players within it, and the general threats and opportunities.

I find the consumer surveys that are carried out to be extremely beneficial and not something I have seen anywhere else. They provided an insightful view of why and which consumers take (or don’t) particular financial products. This can help shape conversations with clients to ensure they make the right strategic decisions for their business.

One of the challenges I have found is that data in the payments space is often piecemeal. With GD all of the data I need is in one place, but it also comes with additional market reports that provide useful extra context and information. Having the ability to set-up alerts on relevant movements in the industry, be it competitors or customers, and have them emailed directly to me, ensures I get early sight of industry activity and don’t have to search for news.
