Research papers on capital structure optimization are relatively easy to write. After all, we can find specific cases to explain the relevant reforms of some world-renowned big companies. The optimization of enterprise capital structure refers to the process of rationalizing its capital structure and achieving the set goals through the adjustment of capital structure, and implementing the strategic management of capital structure optimization for enterprises, so that enterprises are in the process of capital structure optimization. It is of great significance to establish a modern enterprise system with clear property rights, clear rights and responsibilities and scientific management, and to optimize the corporate governance structure formed on the basis of clear property rights. Starting with the concept of inventory, it is found that the main problems of inventory management are inventory backlog, too long inventory turnover days, and the lack of effective control of inventory at the retail end due to the constraints of inventory management mode. It is relatively difficult to put forward some suggestions for improvement after in-depth analysis of the problems.
