How are inefficient firms affected by the reduction in trade restrictions among countries and the continuous increase in international trade?

Inefficient firms face increased competition from more efficient international competitors when trade restrictions are reduced. This heightened competition can lead to a loss of market share, forcing inefficient firms to either innovate, improve their productivity, or reduce costs to survive. If they fail to adapt, these firms may face declining profits or even exit the market altogether. Ultimately, the pressure from international trade can drive overall market efficiency by encouraging less competitive firms to either improve or leave.
