Recently, the official website of the national development and reform commission (NDRC) published the catalogue of guidance for industrial restructuring (the draft version of 2019). Existing industries, production capacity and products are divided into three categories: encouragement, restriction and elimination. Among them, 26 encouragement items, 12 restriction items and 25 elimination items were marked in the fields related to the construction industry.
The direction of the industry often grasp! Small make up here sorted out the relevant content of the construction industry, for the reference of the industry.
The encouraged category mainly refers to the technologies, equipment, products and industries that play an important role in promoting economic and social development and are conducive to meeting people's needs for a better life and promoting high-quality development.
The restriction category is mainly backward technology, which does not meet the requirements for industry access and relevant regulations. It is prohibited to build or expand new production capacity, technology, equipment and products that need to be supervised and improved.
Elimination mainly refers to the outdated technologies, technologies, equipment and products that do not comply with relevant laws and regulations, do not meet the conditions for safe production, seriously waste resources and pollute the environment.
