Countries are not short of priority sectors. Across national development plans, governments routinely identify manufacturing, tourism, agriculture, digital services, pharmaceuticals and other industries as potential drivers of jobs, investment, exports and economic transformation.

Yet why do some priority sectors become engines of growth while others remain priorities on paper? The answer lies in what happens after prioritisation: whether firms can invest, produce efficiently, reach markets and grow.

The obstacles to sector growth are often similar. Tourism businesses struggle with connectivity, skills, finance and approvals.

Manufacturers point to energy, logistics, standards and access to capital. Agribusinesses confront storage, transport, certification and markets. Digital firms face skills shortages, financing gaps, connectivity constraints and uncertain regulation.

This pattern matters. Sector development is about creating the conditions and capabilities that allow firms to invest, become more productive and compete. It requires both removing the constraints that hold firms back and building what the sector needs to grow. While the precise interventions will differ by industry, successful sector transformations tend to follow a practical sequence.

First, fix the constraints that cut across sectors. Energy, transport, finance, skills, digital infrastructure, standards, trade facilitation and regulatory predictability form the common platform on which productive sectors are built. These are horizontal constraints because weaknesses in any one of them can hold back several industries at the same time.

Where the same constraint repeatedly appears across priority sectors, it should be treated as a competitiveness problem rather than addressed through separate incentives or special arrangements. If tourism, manufacturing and agribusiness are all constrained by infrastructure, skills or finance, fixing those conditions can unlock investment across several sectors at once.

Second, address sector-specific challenges. Some constraints are vertical, making it important to understand the economics and particular requirements of each sector.

Tourism illustrates this well. Natural or cultural assets do not automatically create a competitive tourism sector. Growth also depends on air connectivity, transport infrastructure, accommodation, destination development and the quality of the visitor experience alongside effective promotion.

Other sectors require different capabilities. Pharmaceuticals depend on specialised regulation, laboratories, technical skills and quality assurance.

Agribusiness may require irrigation, aggregation, cold chains and links between producers and processors. Understanding these sector economics allows governments to target the constraints that actually determine competitiveness.

Third, build an ecosystem rather than pursue isolated projects. Morocco’s automotive sector illustrates this. Its development went beyond attracting vehicle manufacturers. Industrial infrastructure, logistics, training, export access and supplier development were built around anchor investors. Over time, the ecosystem deepened and one investment helped create the conditions for another.

This is the distinction between attracting a project and building a sector. A major investment should create demand for suppliers, deepen skills, raise standards and attract complementary businesses. Without those linkages, a country may secure a factory, hotel or technology company without developing the wider industry.

Digital economies follow the same logic. Estonia’s digital success was not built on connectivity alone.

Digital identity, interoperable public systems, skills, enabling regulation and widespread adoption created an environment in which digital services and businesses could scale. The lesson is that no single intervention builds a sector. Growth comes from the way different parts of the ecosystem reinforce one another.

Fourth, diagnose the value chain before designing interventions. Broad sector labels can hide the real constraints. Manufacturing consists of very different industries. Agriculture contains distinct value chains.

Sector development requires understanding where value is created, where costs accumulate, which capabilities are missing and what prevents firms from moving into more productive activities. Policy can then address bottlenecks rather than produce another list of generic programmes.

Fifth, coordinate delivery across government. Firms experience the economy horizontally while governments tend to manage it vertically. A tourism investor may depend on transport, immigration, environment, land and investment authorities.

A manufacturer may rely on energy, customs, taxation, standards and skills institutions. Yet no single ministry controls the investor journey.

Coordination is therefore part of competitiveness. Constraints need owners, decisions need timelines and progress needs to be tracked.

Public-private dialogue matters when it produces solutions. Its value should be measured by constraints removed, not meetings held.

Sixth, measure outcomes rather than activity. Launching a strategy is an activity. Hosting an investment conference, signing memoranda and announcing incentives are activities. They may be useful, but none proves that a sector is becoming more competitive.

The outcomes that matter are whether firms are investing, productivity is improving, exports are growing, local suppliers are entering value chains, technology adoption is increasing and more productive jobs are being created.

The private sector has responsibilities too. Government can create conditions for growth. Firms ultimately build the industry. Industry associations should identify shared constraints with evidence and work with government on solutions.

Anchor firms can strengthen local value chains by developing suppliers, skills and standards. Businesses must also invest in technology, capability and productivity rather than wait for policy to do the work.

Countries should continue identifying sectors capable of driving economic transformation. But prioritisation is only the beginning. The real test of a priority sector is not that it appears in a national plan, but that firms within it can invest, become more productive and compete.
