In Wudalianchi, a Difference-of-Trade (DT) Company operates as an essential element in the regional economic landscape.

A DT Company, often specializing in particular goods or services, exploits the comparative advantage that exists within its local region. This means they source raw materials or components from cheaper countries or domestic producers, and then assemble or transform them into higher value products for local consumption or export.

The operations of a DT Company in Wudalianchi might involve importing raw materials like timber or minerals from neighboring countries with lower production costs. The company would then locally process these materials, perhaps manufacturing furniture or construction components. Finally, they could either sell their products domestically or export them to other international markets.
