The study looked at how well Thai garment companies were doing in selling clothes to Japan from 1999 to 2005. They found that clothes made of cotton were selling more, while those made of synthetic fibers were selling less. The amount of clothes sold depended on factors like world trade, the types of clothes being sold, and how competitive the companies were. They also found that some companies were doing better than others based on their size, the quality of their clothes, their prices, and how well they managed their business.
