The study looked at what factors affect how companies on the Hanoi Stock Exchange borrow money. They checked things like profits, company size, and assets. They found that profits and tax benefits make companies borrow less, while bigger companies borrow more. The type of assets a company has didn't really matter. The study shows that big companies borrow more to get tax benefits, supporting the idea that companies balance the benefits of borrowing with the costs. This helps companies make better decisions to improve their performance.
