The financial leverage coefficient refers to the ratio of the change rate of earnings per share to the change rate of pre-tax profit when an enterprise is in debt management. It reflects the risk and income level of the enterprise's debt management, as well as the change of shareholders' equity.

The determining factors of the financial leverage coefficient include the enterprise's debt level, pre-tax profit, debt interest rate, etc. When the enterprise's debt level is higher, pre-tax profit is lower, and the debt interest rate is higher, the financial leverage coefficient will be larger, and the financial risks of the enterprise will be greater.

The financial leverage coefficient is an important indicator for assessing the financial status and risk control ability of an enterprise. Enterprise managers need to plan and control the financial leverage coefficient reasonably based on the actual situation to reduce the financial risks and operational risks of the enterprise and ensure its sustainable development.

Overall, the financial leverage coefficient is an important indicator for assessing the risk and income of an enterprise's debt management, which is of great significance to its operation and development.
