Is it the consumer's buying behavior? If so, the purpose of studying consumers' buying behavior from the standpoint of enterprises should be to determine the trend of the consumer market and reduce the unnecessary waste of funds by enterprises. For example, if more consumers boycott Japanese goods, enterprises will reduce their purchases of Japanese goods and increase domestic products, so that the market will be dominated by domestic products. If you are a student, the school should increase students' sensitivity to the market and let them know more about what you have learned, instead of just reciting theories. This is just my understanding, I don't know if it's right.
