The restricted category adheres to the principles of marketization and legalization, and mainly sets restrictions on safety, environmental protection, energy consumption, water consumption and quality. The production capacity, technology, equipment and products that are no longer overcapacity, can be effectively regulated by the market, have no hidden dangers such as safety and environmental protection after the liberalization of restrictions, and have clear regulatory measures are no longer included in the restricted category. Investment in new projects
falling into the restricted category shall be prohibited. Investment management departments shall not examine and approve, financial institutions shall not grant loans, and departments of natural resources, construction, ecological environment, water conservancy, market supervision, fire control and customs shall not go through relevant formalities.
Those who carry out investment and financing construction in violation of the regulations shall be investigated for the responsibility of the relevant units and personnel. For the existing production capacity that belongs to the restricted category, enterprises are allowed to take measures to upgrade within a certain period of time, and financial institutions continue to support it in accordance with the principle of credit. According to the requirements of optimizing and upgrading the industrial structure, the relevant departments of the state should follow the principle of survival of the fittest and implement classified guidance.
