Linkages refer to the connections or relationships between different elements within a system. These connections can be physical, such as the linkages in a machine that allow parts to move together, or conceptual, like the linkages between ideas in a theory. Understanding linkages helps in analyzing how changes in one part of a system can affect others. In economics, linkages can describe how different sectors, such as agriculture and manufacturing, interact and influence each other. For example, a strong agricultural sector can provide raw materials for manufacturing, creating a beneficial relationship. Recognizing these linkages is essential for effective policy-making and economic planning.
