Essential Pre-requisites for Building a Smart Economy in Cities

Building a smart city is often imagined as a question of technology: sensors, control centres, and digital dashboards. But underneath every successful smart city lies something far less glamorous and far more decisive: a smart economy. A city cannot run intelligent traffic systems, clean water grids, or efficient public transport if it cannot pay for them, sustain them, and keep attracting the money needed to upgrade them. This is why the economics of a smart city deserves as much attention as its technology. Before any city can call itself “smart,” it needs to put certain economic foundations in place. These pre-requisites determine whether a smart city thrives for decades or collapses into a half-finished project. Let us look at what these foundations actually are and why they matter so much.

Smart financing and business models 🔗

The single biggest obstacle to smart city development is money. Smart infrastructure demands huge upfront capital and long-term commitments, which makes traditional funding methods inadequate on their own. A smart economy begins by solving this problem in a structured, sustainable way rather than depending only on government grants.

Sound taxation and own-source revenue 🔗

Most urban local bodies in cities depend heavily on property taxes, but these collections are often kept low due to political sensitivities around raising rates. As a result, much of the revenue goes towards salaries and routine operations, leaving little for capital investment in roads, water networks, or digital infrastructure. A smart economy fixes this by widening the tax base. The 14th Finance Commission, for example, recommended levying taxes on vacant land and improving user charges for water, electricity, parking, and changes in land use. Other instruments include taxes on advertisements, entertainment, and entry into the city. The principle is simple: a city that generates strong own-source revenue is financially credible, and financial credibility is what attracts lenders and investors.

Green financing and sustainability-linked instruments 🔗

Modern investors increasingly want their money to support environmentally responsible projects. This has created a powerful financing opportunity for cities. Green bonds are issued specifically to fund environmentally friendly projects such as renewable energy, water recycling, or urban afforestation, and they attract a class of investors focused on sustainability. The advantage goes beyond image. When a city aligns its resource-mobilisation strategy with a green agenda, it can attract climate-specific investor groups who often accept lower returns, which lowers the overall cost of borrowing. Experts have also pointed out that sustainability-linked financing remains underused, and that credit enhancement measures by the finance ministry and donors could stimulate the municipal bond market and link it to Sustainable Development Goals.

Innovative funding strategies 🔗

Beyond taxes and green bonds, a smart economy keeps several funding tools ready. Municipal bonds allow cities to borrow directly from capital markets for infrastructure. Special Purpose Vehicles (SPVs) are separate companies created to isolate the financial risk of a project, making it easier to finance and manage large works. Researchers studying smart city financing have also proposed crowdfunding, monetising the big data that cities collect, carbon offsets, and smart government bonds as fresh sources of capital. The Pooled Finance Development Fund is another mechanism that helps smaller urban bodies, once seen as high-risk borrowers, access affordable financing through credit enhancement. The lesson is that no single source is enough; a smart economy blends many instruments so that no project stalls for lack of funds.

Public-private partnerships and community financing 🔗

Government money, no matter how well managed, can only cover part of the cost of a smart city. The rest has to come from the private sector and from the community itself. This is where partnerships become a core pre-requisite of the smart economy.

How public-private partnerships work 🔗

A public-private partnership (PPP) is an arrangement in which a private company designs, builds, finances, or operates public infrastructure in collaboration with the government. Common models include Build-Operate-Transfer (BOT) and Design-Build-Finance-Operate (DBFO), which allow inventive financing frameworks combining municipal bonds, SPVs, and revenue-sharing agreements. The scale matters. Of the nearly two lakh crore rupees worth of projects proposed by the winning cities under the Smart Cities Mission, about 23% was expected to come through private investments and PPPs. PPPs bring in not just money but also private-sector efficiency, technology, and management skills. For this to work, the partnership needs transparent governance, clear risk allocation, and strong dispute-resolution mechanisms so that both public and private partners are protected.

The role of the SPV and government support 🔗

Under the Smart Cities Mission, each city set up an SPV as a limited company incorporated under the Companies Act, with the state and the urban local body holding equal equity. This structure lets the city use central and state funds, including equity, as leverage to raise additional money from external sources. The government’s role does not end with grants. Smartcities.gov.in notes that the success of these projects depends on the robustness of the SPV’s revenue model and the comfort it provides to lenders and investors, and that state-backed guarantees through financial intermediaries can serve as instruments of comfort. In other words, a credible SPV with a believable revenue plan is itself a pre-requisite for attracting private capital.

Community and participatory financing 🔗

A smart economy also draws on the people who live in the city. Participatory financing means involving local communities and residents directly in funding and shaping projects. Crowdfunding is one practical form, mobilising small contributions from a large number of people and democratising the financing process. When residents contribute money or are consulted on how funds are spent, two things happen. First, the city taps a new source of capital. Second, and more importantly, citizens feel ownership of the project, which improves how well services are maintained and used over time. User fees for water, transport, and other services also fall into this category, since they make residents direct stakeholders in keeping services efficient. Sustainable service delivery is far more likely when the community has a financial and emotional stake in it.

Foreign direct investment and downsizing the informal economy 🔗

The final pre-requisite looks outward and inward at the same time. A smart economy needs to attract money from abroad while simultaneously bringing more of its own businesses into the formal, taxable, and measurable economy. Both moves expand the resource base a smart city can draw on.

Why foreign direct investment matters 🔗

Foreign direct investment (FDI) is investment made by a foreign company or individual into businesses and infrastructure within a country. For cities, FDI is a powerful engine because infrastructure is one of the sectors that attracts the most foreign direct investment, and the country needs such investment to rebuild ports, highways, and urban systems. The Smart Cities Mission was itself designed partly to attract foreign capital into urban infrastructure, technologies, and services across cities. The numbers show the scale of this opportunity: FDI into construction development sectors such as townships and built-up infrastructure crossed US$26 billion between 2000 and 2021. When foreign capital flows into a city’s businesses and infrastructure, it creates jobs, transfers technology and management know-how, and raises the overall standard of urban services.

Creating the conditions to attract FDI 🔗

FDI does not arrive on its own; it follows good policy and good governance. Studies on infrastructure and growth find that the level of urbanisation, combined with strong physical infrastructure and quality of governance, leads to better development outcomes. Reforms that improve the ease of doing business, simplify approvals, and offer investor facilitation all make a city more attractive to foreign investors. This connects back to the earlier pre-requisites: a city with sound finances, clean governance, and reliable infrastructure is exactly the kind of place foreign investors want to put their money.

Downsizing the informal economy 🔗

A large share of urban economic activity happens informally, outside the tax net and beyond official records. Street vendors, unregistered small workshops, and cash-only businesses are part of daily city life, but an economy dominated by informality is difficult to plan for and finance. Formalisation means bringing these businesses into the regulated economy where they pay taxes, keep records, and access formal credit. The benefits are mutual. As cost and complexity fall, more firms enter the formal economy, which helps them innovate, access credit, and scale efficiently. Digital platforms and shared infrastructure accelerate this shift by formalising transactions and linking small producers with wider markets, while generating millions of jobs and improving access to insurance and welfare benefits. For the city, a larger formal economy means a broader tax base, better data for planning, and a more resilient base of small and medium enterprises. Downsizing informality is therefore not about pushing vendors out; it is about pulling them into a system where they can grow and contribute.

How these pre-requisites fit together 🔗

It is tempting to treat these three areas as separate checklists, but they reinforce one another. Sound taxation and innovative financing build the financial credibility that makes private partners and foreign investors confident. PPPs and community financing spread both the cost and the ownership of projects. FDI brings in external capital and expertise, while formalising the informal economy widens the tax base that underpins everything else. A weakness in one area undermines the others. A city with poor own-source revenue will struggle to attract PPPs; a city with a largely informal economy will find it hard to plan and to draw foreign investment. The smart economy, in this sense, is a system rather than a set of isolated tools. Getting the pre-requisites right is what turns the dream of a smart city into something financially real and sustainable for the long term.

What do you think? If your own city had to raise money for a new smart transport system, which pre-requisite do you think would be the hardest to put in place, and why? And how might a city balance the goal of formalising its informal economy with the livelihoods of the millions who depend on it?
