A particular dress manufacturer closes a factory in South Carolina and moves the factory to Malaysia, where labor costs are lower. This is an example of

de-industrialization

Explanation:

De-industrialization is a process in which there is a shift of industries from an economy.

It is not necessary that the industry is then relocated somewhere else.

But it does not work any further in the city it is setup. Here also, the factory is closed in South Carolina. That is de-industrialization in the current city.

Although, the industry is setup in Malaysia, but the company do not work in its earlier location. And it has shifted from original location.

Thus, it is a case of de-industrialization.
