Why does the increase in social security application show that 0 people are injured at work?

That's because your company doesn't take insurance treatment for work-related injuries.

If the company fails to pay work-related injury insurance for the workers, the workers should complain to the relevant departments before applying for labor arbitration. If the employer fails to pay social insurance premiums for the workers as required, resulting in the workers being unable to enjoy the benefits of work-related injury, unemployment, maternity and medical insurance, and the workers demand the employer to compensate for the losses or pay related expenses as required, it shall be accepted. If the unit fails to pay social insurance to the employee, and the employee cannot enjoy various social insurances because the unit fails to pay, the losses caused may be claimed from the unit, and the labor dispute arbitration committee shall accept such disputes. You can report to the local labor administrative department, which will impose administrative penalties on the unit and supervise it to handle social insurance for workers.
