With the rapid development of the market economy, the reform has not stopped and is progressing in a good direction. For example, it is obvious in the publishing industry in China. Due to the deepening of the reform, the publishing industry has been gradually increasing the number of books sold abroad, which has brought huge profits to enterprises. But on the other hand, it also brings a negative impact on the publishing industry, which is to produce more books while increasing sales volume, increase inventory for enterprises and increase costs. In order to be successful, enterprises must solve the two problems of controlling inventory and improving the competitiveness of enterprises. As the publishing industry is greatly affected by inventory, enterprises should pay more attention to the inventory of the publishing industry. The surplus inventory should be dealt with in a timely manner, which can save costs and increase profits for the enterprise and also meet the development needs of the contemporary society, which is beneficial to enhancing the competitiveness of the enterprise.
