Analysis and optimization strategies of air environmental protection industry chains

Under the background of the urgent demand of air pollution control and national promotion of environmental protection industry development, and based on the definition of the concept and implications about air environmental protection industry, the characteristics and development status of different links in the upstream, downstream and mid-stream industry chains were analyzed from the aspects of leading function, product type and market situation. The upstream is the supply chain, mainly providing the downstream with raw materials, spare parts, technology and product development, etc. The mid-stream is the production chain which is responsible for equipment production concerning dust removal, desulfurization, denitration, VOCs treatment, etc. The downstream is the service chain, including air environmental technology services, environmental consulting services, air pollution facilities operation, air environment trade and financial services. On the basis of analyzing industry chain structure and development problems from links in industry chain, some suggestions to optimize the industrial chain were put forward, such as strengthening technological innovation, enhancing the comprehensive service ability of the air environment service industry, and perfecting related policies and legal system, etc.
