Unemployment rate: 18.2%. Reason: In order to maximize profits, supply exceeds demand. According to official website, the human resources management department of Nanning, the unemployment rate of college students in Nanning in recent five years is 18.2%, because:

1. Enterprises deliberately reduce the employment of college students in order to maximize profits. If all enterprises adopt the same method, the effective demand in the market will be insufficient, leading to unemployment.

2. Supply exceeds demand, higher education develops too fast, and the supply of college graduates exceeds demand, which leads to intellectual unemployment of college students.
