In what stage of tourism destination development will it focus on existing core products?

In the middle and late stages of tourism destination development, focus on existing core products.

Core products:

Any product is composed of three layers. The innermost layer is the core product, the second layer is peripheral products, and the third layer is epitaxial products. The core product refers to the basic utility or benefit of the product provided to the customer.

The core product is the benefit that customers really want to buy, that is, the use value of the product. For example, for washing machines, consumers want to buy "convenience, speed, and cleanness"; for movie theaters, consumers want to buy It's entertainment.

Fundamentally speaking, every product is essentially a service provided to solve a problem. For example: health products are products targeted at mid- to high-end consumer groups, and their prices are quite high. As a high-priced product, first of all, in the concept of core products, it must have ultra-mainstream quality and be reliable in quality assessment. And most consumers don't think this is a problem.
