The reasons why short-term loans and accounts payable account for a large proportion of current liabilities are: high borrowing cost, low investment cost and business development needs.

1. High loan cost: Enterprises will choose other financing methods, such as mortgage loan, cheque discount, accounts receivable financing, etc. These financing forms are more flexible than bank loans, resulting in an increase in the proportion of other payables to current liabilities.

2. Low investment cost: The low investment cost of enterprises can effectively reduce the financing cost, thus increasing the proportion of other payables in current liabilities.

3. Business development needs: In the process of development and growth, enterprises may encounter some temporary capital needs, so in order to meet these needs, enterprises will increase other payables to meet the capital needs, thus increasing the proportion of other payables in current liabilities.
