First of all, college students' entrepreneurship is limited by personal qualities, market environment (mainly small market), sources of funds and other factors. The success rate is much lower than starting a business after graduation. It is definitely uneconomical to choose something with a low success rate and treat suboptimal and suboptimal as the best. This is one aspect that does more harm than good.
Second, entrepreneurial failure, although experienced, is often paid by parents, which may lead to higher adverse selection and moral hazard. This does more harm than good to entrepreneurs and the market.
Third, although some funds are provided by the government to college students, on the one hand, this part of funds is small, on the other hand, the government needs stricter requirements to pay for high risks, which may not be suitable for college students, but less stringent conditions will still lead to adverse selection and moral ethos. It's not good for anyone
Fourth, success in starting a business at school is not necessarily a good thing. First, most college students' entrepreneurial projects are not competitive in the real market, and most of them are projects with no market capacity such as dormitory convenience stores and campus agency industries.
5. Success leads to wrong self-evaluation, complacency, from door-to-door entrepreneurship to no real entrepreneurship in the adult world. Even if not, the transformation of this entrepreneurial project is very difficult. It may lead to great opportunity cost and uneconomical.
