Infrastructure, administrative reform, and investment in skills can improve the return to private enterprise. Better transport can widen a firm's market; reliable utilities can reduce operating uncertainty; clearer procedures can lower the cost of entry. These effects differ from the immediate demand created by construction contracts.
At the same time, a large project program can compete with independent firms for labor, contractors, land, credit, and management capacity. Higher demand can raise input prices or delay other investment. The net effect depends on available capacity and the design of procurement and financing, rather than the public or private label alone.
An evaluation should therefore distinguish the demand impulse from the productivity effect. The former is visible in orders and expenditure during implementation. The latter requires evidence of lower costs, improved reliability, greater market access, or higher output from existing resources after the asset or reform becomes operational.
Project sequencing matters. Completing a complementary network can unlock private activity more effectively than beginning several disconnected assets. Conversely, an impressive construction pipeline can leave firms waiting for the last connection or operating agreement. Measuring the productive service delivered helps separate effective enabling investment from expenditure that has yet to yield its intended capacity.
Oil-linked demand also reaches firms through household balance sheets. A public employee spending wages at a private retailer creates private sales financed through a fiscal channel; an independent exporter selling abroad has a different immediate demand source. Neither transaction should be excluded from non-oil production. The distinction matters when testing sensitivity to expenditure restraint. A scenario should identify which incomes and contracts change, their timing, and the ability of businesses to replace customers. Applying one uniform percentage reduction to all non-oil activity would conceal those differences and overstate the precision of the exercise.
For suppliers, payment timing provides another test of resilience. A contractor with a diversified order book can still face liquidity pressure if a large customer delays settlement. Revenue dependence, working-capital exposure, and the ultimate ownership of the customer should therefore be measured separately.
