2. Meeting and guiding consumers' needs is the starting point and center of marketing activities. Enterprises must take consumers as the center, face the changing environment and make correct responses to meet the changing needs of consumers. Meeting the needs of consumers includes not only the current needs, but also the potential needs in the future. The current demand is the tendency to buy existing products, while the potential demand is the desire for a certain function of products that have not yet come out. Enterprises should stimulate and guide consumers to generate new demands by developing products and using various marketing methods.
