Want to start a company in the future. What major should I study?

As long as you have a business mind, no matter what major you study, you can start a company in the future.

It is best to study economics, such as management, business administration, human resources and so on.

Actually, it has nothing to do with this major. The key is to have a business mind and an eye for business opportunities. You see so many bosses now, some of them have majors related to the company they are engaged in when they go to school, so it doesn't matter what their major is, but your personal ability is the key.
