Vigorously implement the industrial chain upgrading project. Cultivate leading enterprises in the fine phosphorus chemical industry chain, with the leading enterprises as the "chain masters", gather a group of specialized, special and new "little giant" fine phosphorus chemical enterprises, and join associations, chambers of commerce, and new promotion agencies to take the lead in building the upstream and downstream of the phosphorus chemical industry chain Enterprise alliance, promote the integrated development of fine phosphorus chemical industry chain, and form high-end phosphorus-based electronic-grade chemical industry chain, phosphorus-silicon fine chemical product industry chain, fluorine-based new material and fluorine-containing chemical industry chain, new energy material industry chain, Phosphogypsum phosphorus slag solid waste production of new wall material industry chain.

In response to the key core technology needs of the fine phosphorus chemical industry chain, the government takes the lead and supports the leading enterprises in the fine phosphorus chemical industry chain to build national and provincial industrial innovation centers, technology innovation centers, and manufacturing innovation centers. Using methods such as the unveiling system, support leading enterprises to take the lead in making breakthroughs in the industrialization of key industrial chain "stuck neck" technologies. Master supergravity technology, membrane process coupling technology, micro-chemical technology, magnetically stabilized bed technology, supercritical fluid technology, develop high-efficiency solid precious metal catalysts, new membrane separation materials, new photocatalysts, electronic grade phosphorus chemicals and etching solutions and other products, Development of new energy-saving and environmentally friendly building materials made from phosphogypsum, production of new phosphogypsum bricks, cement retarder from phosphogypsum, ammonium sulfate from phosphogypsum, glass-ceramic from yellow phosphorus slag, and production of carbon-one chemicals (formic acid, Sodium formate, formamide, ethylene glycol) and other key chemical technologies.
