How to understand that the upstream industry chain in the pension industry chain is equipment and talents?

With equipment and talents, there is a pension industry.

The concept of industrial chain is derived from the concept of "division of labor" in Adam Smith's The Wealth of Nations, which is manifested in the mutual value exchange between upstream and downstream industries, the delivery of products or services and the feedback of information, and then the interlocking relationship between industries.

A large number of studies have proved that a complete pension industry chain should include core industries, pillar industries and upstream and downstream supporting industries. After several years of industrial development and integration, China's existing pension industry chain takes pension service as the core industry, food, medical rehabilitation, health care, nursing, tourism and leisure industries as the pillars, health care products production, medicines, auxiliary devices and other industries as the upstream industries, and pension real estate, pension financial services, funeral and other industries as the downstream industries.
