What term describes a zone consisting of modern factories at the edge of a settlement?

The term that accurately describes a zone consisting of modern factories at the edge of a settlement is "new industrial zone." This term specifically refers to areas that have been designated for industrial use, often associated with the latest technological advancements and constructed with modern facilities. These zones are strategically situated on the periphery of urban areas to benefit from easier access to transport links and to minimize the impact of industrial activities on residential zones.

While "commercial center," "manufacturing hub," and "business park" are terms related to economic activities, they do not precisely refer to modern factories located on the outskirts of settlements. A commercial center typically focuses on retail and services, a manufacturing hub indicates a broader area where manufacturing occurs but isn't limited to modern factories, and a business park usually accommodates various businesses that may not be exclusively industrial. Hence, the term "new industrial zone" clearly identifies the specific type of area being referred to in the question.
