A characteristic of specialization is that it causes entities to rely on one another, resulting in:

Specialization refers to the process where individuals, firms, or countries focus on the production of a limited range of goods and services to improve efficiency and productivity. When entities engage in specialization, they become highly skilled or efficient in their specific areas, leading to a greater output in those areas.

As a result, they develop products or services that often complement one another, creating a scenario where they depend on each other for the full range of goods or services needed. This interconnectedness among specialized producers is termed interdependence. Entities become reliant on others to provide different goods or services that they do not produce themselves. Interdependence is a key principle in economics, highlighting how specialization fosters cooperation and collaboration in the market, enhancing overall economic efficiency and growth.

Thus, the characteristic of specialization leading to reliance among entities is best captured by the concept of interdependence, which showcases the benefits of collaborative economic relationships formed through specialized production.
