Speed up the adjustment of industrial structure.

Speed up the adjustment of industrial structure. Resolutely eliminate backward kinetic energy. Implement the "four ups and four pressures", and insist on "upgrading the new and suppressing the old", "upgrading the big and suppressing the small", "upping the high pressure and low", and "upping the whole and suppressing the dispersion." Promote the green transformation of key industries, build a green industrial chain supply chain, vigorously promote cleaner production, and strive to improve the green level of industrial parks. By the end of 2025, the proportion of eco-industrial parks will reach more than 50% of industrial parks.
