Maslow's hierarchy of needs, also known as "basic hierarchy of needs", is one of the theories of behavioral science, which was put forward by American psychologist abraham maslow in his paper "Theory of Human Motivation" 1943. The book divides people's needs from low to high like a ladder into five levels, namely: physiological needs, security needs, social needs, respect needs and self-realization needs. This theory has had a far-reaching impact since it came out, and it has been applied in human resources industry, education industry, floating population management, young teachers management, water resources development and utilization, management psychology, enterprise salary formulation and so on.
