The thesis chooses the application of cost-volume-profit analysis in decision-making, but taking an industry as an example, I don't know what industry can highlight this theme.
Cost-volume-profit analysis focuses on the critical point of profit and loss, that is, the point where income is equal to fixed cost and the whole is in a state of no loss. Therefore, in order to make the results of the cost-volume-profit analysis meaningful, it is necessary to choose those industries with relatively high fixed costs, that is, industries with relatively large fixed assets investment, and manufacturing industries with relatively large fixed assets investment, that is, C industries in the industry classification of the CSRC. For graduation thesis, you can directly take company C as an example.
