The basis of developing service industry is that a large number of people are willing to accept expensive services, and this needs the support of economic foundation, or that people can change their concept of thrift and be able to spend money to enjoy services if they have extensive employment and high income to a certain extent. If a country has not even achieved industrialization, then the people of this country will definitely have a bad employment situation, low income, impossible concept progress and no money. How do they support the development of service industry? Therefore, in general, we must go through the process of industrialization first. When people get rich, a large number of young people realize their awareness of employment and consumption, so as to promote the great development of the service industry. This is also the reason why the output value of service industry in developed countries is high.
