Low-carbon industrial structure and industrial structure optimization
Rationalization of the industrial structure in the low-carbon economy mode is based on the concept of saving economy, lasting economy and accompanied economy, under the principle to reduction of resources , re-use , recycling , and generating alternative, regarding the use of material energy echelon and closed loop as the path, and by the means of natural resources, reduction , recovery , regeneration, based on enhancing socio-economic development and sustainable use of resources , environment constantly purification, coordination between industry and industry and improve the level of industry association to achieve scientific and rational , long-lasting steady-state growth in the harmonious industrial structure state .
In short , in order to achieve low-carbon industrial structure , the first is to reduce fossil , automotive , steel , transportation , chemical industry , building materials and other high-carbon industries cited in the industrial chain , these industries upstream and downstream industries "low-carbon " ; Second is to reduce the high-carbon industries, especially the proportion of heavy and chemical industries in the national economy as a whole , promote the industry and product extends to both ends of the profit curve : Extends to the front-end , from the form of eco-design start with independent intellectual property rights ; Extending to the back-end form of brand and sales network, improve the core competitiveness of the industrial structure of the national economy , and finally to the trend in the low-carbon economy standards .
