# Foreign-owned production and domestic linkages

Data Note · International Trade
Foreign ownership and domestic production content are different classifications. A foreign-owned exporter can purchase extensively from local suppliers, employ resident workers and generate substantial domestic value added. A domestically owned exporter can rely heavily on imported components. Ownership alone cannot determine which contributes more to local production.

Vietnam's National Statistics Office reports [investment and merchandise trade in separate parts of its economic release](https://www.nso.gov.vn/en/data-and-statistics/2026/08/press-release-socio-economic-performance-in-the-q2-and-in-the-first-half-of-2026/). The distinction should be retained analytically. An investment relationship, an export transaction and the sourcing of production inputs are related observations, but none is a complete substitute for the others.

## Hold export receipts equal

Take two hypothetical resident plants, each exporting 100 of output. Plant A is foreign-owned and imports intermediate inputs worth 80. Its remaining value added is 20, consisting of resident wages of 10 and operating income of 10. Plant B is domestically owned, imports inputs worth 90 and generates value added of 10, consisting of wages of 7 and operating income of 3.

| Hypothetical resident producer | Export receipts | Imported intermediates | Domestic value added |
| --- | ---: | ---: | ---: |
| A, foreign-owned | 100 | 80 | 20 |
| B, domestically owned | 100 | 90 | 10 |

The foreign-owned plant contributes twice as much domestic value added in this restricted example. Nothing in that result implies that foreign ownership generally produces greater local content. The example disproves an automatic equivalence between the owner's residence and the origin of the export's value.

Now assume all A's operating income accrues to its nonresident owner and all B's accrues to residents. Ignoring depreciation, taxes and other flows, the resident income retained from each plant would be 10. The production comparison and the resident-income comparison then give different results because they apply different boundaries.

## Local purchases need a second look

A purchase from a resident distributor may contain mostly imported goods. A purchase from a foreign-owned resident supplier may embody substantial local labor and production. Classifying invoices by the supplier's ownership does not resolve the origin of their value added.

Tracing domestic linkages requires information on what is produced locally, the imports embodied in those inputs and the domestic services used along the chain. For a simple direct supplier relationship, transaction records can help establish the immediate connection. Assessing indirect linkages requires a wider production account or suitably detailed input-output information.

The existence of a local supplier relationship also differs from a technology spillover. A purchase establishes demand for an input; it does not prove that knowledge transferred, productivity rose or domestic firms gained the ability to supply unrelated customers. Such claims need evidence about capabilities and outcomes beyond the sourcing transaction.

## Read the statistics at their own boundaries

An ownership-based export total can reveal which types of enterprises conduct cross-border sales. It does not disclose the full distribution of wages, operating income, taxes or imported input costs behind those sales. Nor does the export total establish how much new investment was installed during the same period.

For analysis of Vietnam's production links, the appropriate table separates ownership, residence, export value, direct and indirect input origin, and income recipients. Those distinctions permit useful questions about supplier development and income distribution without assuming their answers from the foreign-invested-sector label.

A mature linkage assessment therefore asks what resident production takes place and who receives the resulting income. The nationality of the shareholder remains relevant, particularly for cross-border earnings, but it cannot serve as a shortcut for measuring either domestic value added or the development of local capabilities.
