Trade networks are systems that connect different regions or countries for the exchange of goods and services. These networks can involve various routes, including land, sea, and air, facilitating the movement of products like spices, textiles, and electronics. They play a crucial role in the global economy by allowing access to resources that may not be available locally. Historically, trade networks have evolved over time, with notable examples such as the Silk Road and the Transatlantic Trade. These routes not only enabled the exchange of commodities but also facilitated cultural interactions and the spread of ideas. Today, modern trade networks continue to shape international relations and economic development.
