The chemical industry chain is a vital component of modern industry, encompassing a complete ecosystem from raw materials to end products. Its upstream primarily involves the extraction and processing of essential resources such as petroleum, natural gas, and coal. The midstream focuses on the production of basic chemicals, polymers, and new materials, while the downstream extends to diverse applications, including plastics, coatings, pharmaceuticals, and agrochemicals.

As a highly technology-intensive sector, the chemical industry chain drives green and sustainable development through innovation, serving a wide range of industries such as automotive, construction, electronics, textiles, and food. Furthermore, the synergy between the upstream and downstream segments significantly enhances efficiency and reduces costs through supply chain optimization and intelligent management.

In the context of globalization, the chemical industry chain is transitioning towards digitalization, intelligence, and low-carbon solutions. Emerging technologies such as industrial IoT, AI, and blockchain are introducing new momentum for integration and efficiency enhancement. The chemical industry chain plays an irreplaceable role in driving economic growth and improving quality of life and will continue to evolve towards high-value-added and sustainable development in the future.
