The service economy, as a new form of economy, is reflected in the shift from a labour-intensive to a knowledge-intensive service industry, with modern service industries with a high knowledge and technology content gradually occupying a dominant position in the service sector. The service economy occupies an extremely important position in the composition of the national economy, and it has a height that cannot be reached by the general economic situation. It can be said that the service economy has penetrated into all aspects of all enterprises.
