I'm in the electronics industry, can any of you tell me: what is the meaning of upstream and downstream?

The upstream industry refers to the industry that is at the beginning of the whole industrial chain, providing raw materials and components manufacturing and production.

Inside the broad industry category, upstream enterprises are relative to downstream enterprises, referring to enterprises and manufacturers at the initial stage of the industry's production and business, and these manufacturers mainly produce manufacturers of raw materials and primary products, etc. that are necessary for downstream enterprises. Downstream companies mainly process and modify raw materials and convert them into actual products for production and life.

It can be said that upstream and downstream enterprises are interdependent. Without the raw materials provided by the upstream enterprises, the downstream enterprises are like a clever woman without rice; if there is no downstream enterprise production products into the market, the upstream enterprise's materials will be heroes without use. Therefore, the upstream enterprises and downstream enterprises in various industries should be the same sweet **** bitter, mutual assistance and mutual profit, *** with the survival and development.

In fact, the upstream and downstream is a relative concept in the modern production industry chain, than the traditional division of agriculture, heavy industry, light industry, has a more detailed and wider application value. The development trend of economic globalization makes the correlation between industries and the whole socio-economic development increase continuously, and the connection between industries and related industries become more inseparable. Except for the production of certain terminal consumer goods (such as certain home appliances), the vast majority of industries are upstream industries from one point of view and downstream industries from another point of view.

When discussing issues such as the circular economy, the concept of "midstream industries" sometimes arises. For example, agriculture is the upstream industry of food processing, textile, furniture industry, etc., and at the same time is the downstream industry of fertilizer, pesticide and other production enterprises. Textile printing and dyeing is the downstream industry of the chemical fiber industry, and at the same time is the upstream industry of garment processing. Then, textile printing and dyeing is a midstream industry between the chemical fiber industry and garment processing industry.
