Connect transport, technology and policy to a cost or constraint.
Lower shipping and communication costs can make cross-border transactions worthwhile and allow production stages to be coordinated across locations. Better logistics, digital payment systems and reliable information reduce time, uncertainty and search costs. Lower policy barriers and more predictable rules can widen market access and support investment. Conversely, conflict, sanctions, border restrictions, higher freight costs or supply-chain risks can discourage some flows. A firm can diversify suppliers without ending international integration: it may replace a concentrated foreign source with several other foreign sources.
- Technology and delivery
- Better communication, transport and logistics (organising storage and delivery) can reduce the time, cost and uncertainty of trading across borders.
- Policy and risk
- Simpler border procedures can widen market access. Conflict, restrictions or unreliable routes can make the same international arrangement less attractive.
- Diversification
- Diversification means spreading purchases across suppliers. Replacing one foreign source with several others changes the network; it need not reduce globalisation.
Avoid one-direction predictions
Political and commercial risk
Uncertain rules or disruption can deter a factory investment expected to last many years, even if the tariff, a tax on imports, is unchanged.
Regional reorganisation
Firms may move activity between foreign locations. Identify whether global integration falls or its geography changes.
Feedback
A larger network can lower cost per unit, but suppliers may share the same port or shipping route. Their risks are correlated when the same disruption can affect them together.
Worked example: Faster customs, then a disrupted route
A component importer gains an electronic customs process that cuts delivery delays. Later, disruptions affect its main shipping route, so it adds suppliers in two other countries.
- Faster customs processing reduces waiting and inventory costs, making cross-border sourcing more attractive.
- Route disruption raises expected cost and uncertainty, potentially reversing part of that gain.
- Adding foreign suppliers reduces concentration; it is not the same as replacing imports with domestic production.
- The final effect on trade depends on the savings, alternative capacity and reliability, not on technology or policy labels alone.
Watch out for this
Any change in suppliers is deglobalisation.
Geographic diversification can preserve or expand international links while reducing reliance on one source.
Check your understanding
Why can reliable digital coordination encourage an international production network?
- It reduces communication and coordination costs.
- It eliminates every transport and policy cost.
- It guarantees every country gains equally.
