The medical device industry is an important midstream industry, with upstream nonferrous metals, chemicals, steel, the Internet, and biomedical materials industries, while downstream industries such as insurance, service, pharmaceutical circulation, and healthcare are connected. The development of the medical device industry drives the development of a number of upstream industries, while the relationship between products and service channels affects downstream industries, including hospitals, pharmaceutical specialty stores, other medical institutions, and end consumers.

The pharmaceutical industry can be mainly divided into raw materials, chemical preparations, biological products, traditional Chinese medicine, and health products. Among them, traditional Chinese medicine is an outstanding cultural heritage in ancient China, which has now spread to Southeast Asian countries, even affecting Europe and North America. The pharmaceutical industry is highly specialized and heavily regulated. The industrial chain is long and complex, from upstream API, Chinese herbal medicine planting and even scientific research institutes to intermediate chemical drugs and traditional Chinese patent medicines and simple preparations, to distributors, medical institutions and retail terminals, and finally to consumers. For pharmaceutical companies, the biggest impact is on the pharmaceutical business and medical system. Affected by the relationship between supply and demand, terminals, mainly hospitals and pharmacies, control the fate of pharmaceutical companies.
