Journal of Environmental Engineering Technology
Based on the definition of the concept and connotation of the atmospheric environmental protection industry chain, the characteristics and development status of the different links of the upper, middle and lower reaches of the atmospheric environmental protection industry chain are analyzed from the aspects of leading functions, product types and market conditions.
Under the background of urgent demand for air pollution control and the country's vigorous promotion of the development of atmospheric environmental protection industry, based on the definition of the concept and connotation of the atmospheric environmental protection industry chain, the atmospheric environmental protection industry chain is analyzed from the aspects of leading functions, product types and market conditions. The characteristics and development status of different links in the middle and lower reaches. The upstream of the atmospheric environmental protection industry chain is the supply chain, which mainly provides research and development of raw materials, parts, technologies and products for middle and downstream enterprises. The middle reaches are production chains, which mainly include the production of equipment such as dust removal, desulfurization, denitrification and VOCs treatment; It is a service chain, which mainly includes air environment technology, atmospheric environment consultation, air pollution facility operation, atmospheric environment trade and financial service industry. On the basis of analyzing the problems existing in the development of various aspects of the atmospheric environmental protection industry chain, the paper puts forward suggestions for optimizing the industrial chain from the aspects of strengthening technological innovation, improving the comprehensive service capability of the atmospheric environment service industry, and improving policies and regulations.
As an important area for the classification of environmental protection industries by the Organisation for Economic Co-operation and Development (OECD), the atmospheric environmental protection industry has played an active role in promoting air pollution prevention and control, improving the quality of the atmospheric environment, and promoting sustainable economic and social development in recent years. . The Notice of the State Council on the Printing and Control of Air Pollution Prevention and Control Action Plan (Guo Fa [2013] No. 37) clearly states that it is necessary to form an air pollution prevention and control mechanism for government leadership, enterprise governance, and public participation, and encourage and Under the guidance, the atmospheric environmental protection industry has ushered in a new opportunity for rapid development. However, in view of the development of the atmospheric environmental protection industry, there are still problems such as insufficient technological innovation, insufficient investment in research and development, and imperfect industrial chains. There are not many scholars specializing in the research on atmospheric environmental protection industry at home and abroad. The relevant researches mostly focus on the constraints of the development of the environmental protection industry, fiscal policy, development status, etc., and there are few analyses of the environmental protection industry chain structure and industrial chain optimization. Aspect research. Therefore, the author deeply analyzes the structure of the atmospheric environmental protection industry chain, including the composition and relationship of the upper, middle and lower reaches, identifies the links of the industry chain lacking chain and chain breaking, and proposes the improvement of the entire industrial chain of China's atmospheric environmental protection industry chain. Optimize countermeasures, in order to deepen the theory of atmospheric environmental protection industry, promote the development of atmospheric environmental protection industry, and optimize the provision of methods for China's atmospheric environmental protection industry chain.
1 concept and connotation
1.1 Conception of Atmospheric Environmental Protection Industry Chain
In 1992, the OECD defined the concept of environmental protection industry as terminal control and terminal management. Specifically, it refers to industries that provide products and services in environmental pollution control and emission reduction, pollution control, and waste utilization. This is adopted by most European countries. A narrow definition. Broadly speaking, the environmental protection industry not only includes the definition of a narrow environmental protection industry, but also includes clean technology, clean products and ecological environment construction. The definition of environmental protection industry by Chinese scholars is mainly based on the broad definition. The environmental protection industry is a general term for technological development, product production, resource utilization, information services, and engineering contracting for the purpose of preventing environmental pollution and improving the ecological environment. Based on this, the definition of the concept of air pollution control industry in China is mainly based on the definition of environmental protection industry of OECD, focusing on the end treatment and terminal control of air pollution. The atmospheric environmental protection industry is mainly based on the definition of general environmental protection industry, which refers to the provision of technologies, products and services for the purpose of improving the quality of the atmospheric environment for air pollution control and emission reduction (including source prevention, process control, and end-of-pipe treatment). Industries such as.
To define the concept of the atmospheric environmental protection industry chain, it is also necessary to have a clear understanding of the industrial chain. The term "industrial chain" was first proposed by Chinese scholars, but domestic scholars have not yet formed a unified understanding of the concept of industrial chain. By comparing and analyzing the definitions given by domestic scholars, Liu Guifu proposed that the scientific definition of the industrial chain is the same industry or different. Industrial enterprises, with products as the target, with input and output as the link, value added as the guide, to meet the needs of users, based on specific logical connections and space-time layout, the upper and lower related, dynamic chained intermediate organization.
From the perspective of industry types, the atmospheric environmental protection industry mainly includes design consultation (production technology, structural optimization consulting), technology, clean product research and development, raw material production and supply, atmospheric environmental protection equipment, product production, and atmospheric environmental protection services. It can be seen that the atmospheric environmental protection industry system covers the industries and sectors involved in the whole process of air pollution control, including raw material suppliers, technology and product research and development enterprises, equipment manufacturers, parts suppliers, service providers (front-end design consulting, Back-end operations, management, etc., and other industries and departments. Combined with the definition of atmospheric environmental protection industry, industrial chain and other scholars, the atmospheric environmental protection industry chain can be defined as: a multi-sectoral system that provides technology, products, equipment, information and services for the whole process of air pollution control and emission reduction. With products and technologies as inputs, we provide users with products and services for air pollution control, which are oriented to value added to meet the needs of users for the improvement of atmospheric environmental quality.
1.2 Analysis of the connotation of the atmosphere environmental protection industry chain
According to the definition of the atmospheric environmental protection industry chain, its meaning mainly includes: 1) It is composed of enterprises of different industry types, including technology and product research and development enterprises, manufacturing enterprises providing raw materials and parts, as well as design consultation, operation, maintenance, The service industry enterprises such as monitoring are a comprehensive industrial organization covering all fields and industries, cross-industry and infiltration; 2) the comprehensive improvement of air pollution control and the strengthening of multi-pollutant emission control are the construction of the atmospheric environmental protection industry chain or The driving force of development, therefore the atmospheric environmental protection industry chain to meet the user's goal of air pollution control and emission reduction, its leading industrial functional attributes to reduce atmospheric pollutant emissions, improve the quality of the atmospheric environment; 3) value-oriented, from the theory It is said that enterprises in the industrial chain from the upstream to the middle to the downstream are a process of continuous value-added, until the downstream end products and services are purchased to realize the value of the industrial chain.
2 Atmospheric environmental protection industry chain structure and type analysis
2.1 The overall framework of the atmospheric environmental protection industry chain
The atmospheric environmental protection industry chain consists of three links: the upstream supply chain, the midstream production chain, and the downstream service chain. The overall framework of the industrial chain is shown in Figure 1.
2.2 Analysis of the characteristics of different links in the industrial chain
2.2.1 upstream supply chain
The upstream of the atmospheric environmental protection industry chain is the supply chain. The number of enterprises in China's atmospheric environmental protection industry chain is inverted pyramid. The enterprises belonging to the supply chain are relatively more in the various links of the atmospheric environmental protection industry chain, mainly distributed in the economically developed Yangtze River Delta and the Pearl River Delta. The region presents a market pattern with a large number, small scale and scattered distribution.
The supply chain enterprises mainly provide raw materials for the middle and lower reaches, parts and components required for the production of atmospheric environmental protection equipment, design optimization of atmospheric environmental protection projects, production of catalysts and pharmaceuticals, and research and development of new technologies and new products. In order to ensure the normal operation of production activities, it needs the support of industries and departments such as equipment manufacturing, pharmaceutical manufacturing, chemical, electronics, and scientific research units.
The supply of spare parts includes standard parts and non-standard parts. At present, domestic manufacturers can meet the demand of some key parts, but pulse valves, circulating pumps, etc. still need to be imported due to the technical level behind foreign manufacturers; the raw materials are mainly in dust removal. Chemical and building materials with key functions in desulfurization, denitrification and other processes, represented by special fibers and filter materials, activated carbon, ceramic regenerators, etc. Currently, the high-end fiber and filter materials market is mainly monopolized by foreign manufacturers; For environmentally friendly treatments required for special atmospheric pollutants, such as desulfurization, denitrification, reducing agents and catalysts in vehicle exhaust treatment, the demand for reducing agents in air pollution control by domestic manufacturers is basically satisfactory, but the denitration catalysts The production technology is still mainly based on introduction; the research and development of new technologies and new products is an important part of the supply chain. The research institutes or high-tech enterprises provide services for the middle and lower reaches. In recent years, the air pollution control enterprises independently research and develop or jointly research institutes The proportion has gradually increased. According to the statistics of the environmental protection industry data manual, in 2011, the R&D enterprises of air pollution control technology accounted for about 20% of the total number of environmental technology research and development enterprises, and mainly concentrated on the research and development of dust removal technology and flue gas desulfurization technology.
2.2.2 Midstream production chain
The middle reaches of the atmospheric environmental protection industry chain is the production chain, and the enterprises belonging to the production chain are in the middle stage in the inverted pyramid structure of the atmospheric environmental protection industry chain. The market competition in the production chain is relatively complete. The current products are not highly differentiated in the market, and the competition among manufacturers is strong.
The production chain mainly includes dust removal, desulfurization, denitrification, VOCs treatment, and production of motor vehicle exhaust gas purification equipment. At present, desulfurization, denitrification and dust removal are the three core sectors of the production chain. In 2011, air pollution control equipment manufacturers accounted for 32% of the production of environmentally friendly products, and the industrial sales value of air pollution control equipment accounted for 37% of the total industrial output value of environmentally friendly products. During the “Twelfth Five-Year Plan†period, the output values ​​of various sub-sectors including flue gas desulfurization process supporting equipment and flue gas denitration process supporting equipment have been greatly improved, and dust removal equipment has decreased slightly (Table 1).
From the market situation, with the tightening of air pollutant emission standards, the introduction of the "Air Pollution Prevention Action Plan", desulfurization and denitrification equipment have been widely used in the power industry, including non-electrical industries including steel, cement, nonferrous metals, industrial boilers. Applications such as these are also increasing. Especially in the steel industry, the demand is the largest. In the future, the non-electrical industry is the growth point of the desulfurization industry. At present, the competition pattern of the desulfurization industry is relatively stable and the market concentration is high. The denitrification industry started late, with the nitrogen during the “Twelfth Five-Year Plan†period. The assessment of oxide emission indicators has rapidly expanded the market scale, but it has also led to a relatively chaotic competition pattern; the demand for dust removal equipment has continued to grow during the “Eleventh Five-Year Plan†and “Twelfth Five-Year Plan†periods, especially in the ESP market. However, the total output value of the bag-type dust removal industry has continued to decline in recent years, mainly due to overcapacity in the bag-type dust removal industry. The competition is too fierce and the innovation drive is insufficient. The VOCs treatment equipment is the air pollutant emission reduction policy and the Air Pollution Prevention Action Plan for the past two years. The implementation of the rapid development of the VOCs governance industry in 2014, the total output value of about 7 billion yuan, profits of 10% to 15%, the current governance technology is uneven, has not yet formed a leading enterprise with driving ability, VOCs monitoring capacity is insufficient Online monitoring equipment can not meet regulatory requirements, so the market potential of VOCs governance equipment is large; the main package of motor vehicle exhaust purification equipment market In the three vehicles environmental protection equipment, environmental protection equipment, new cars, new energy vehicles and related products.
2.2.3 Downstream service chain
The downstream of the atmospheric environmental protection industry chain is the service chain. The service chain enterprises are at the bottom of the inverted pyramid structure of the atmospheric environmental protection industry chain, and the number is relatively small.
China's environmental service industry is defined as environmental-related service trade activities, and thus the atmospheric environment service industry is a service trade activity related to the atmospheric environment. In the early stage of its development, it mainly refers to the provision of services for exhaust gas treatment facilities. As the demand grows, the field of atmospheric environmental services has gradually broadened. According to the characteristics of the atmospheric environment service industry, it specifically covers the original State Environmental Protection Administration proposed in 2000. Four of the six categories of environmental services (Table 2) mainly include atmospheric environmental technology service industry, atmospheric environment consulting service industry, air pollution facility operation service industry, atmospheric environment trade and financial service industry.
The atmospheric environment service industry is the most promising component in the development of the atmospheric environmental protection industry. Its development started late and developed rapidly. In 2011, the atmospheric environment service industry accounted for about 15% of the atmospheric environmental protection industry. By 2016, the proportion of the environmental service industry in the environmental protection industry has exceeded 50%, and the proportion of the atmospheric environment service industry has also increased significantly, but compared with developed countries. There is still a certain gap. The main customers of the atmospheric environment service industry are industrial enterprises, including the power industry, cement, building materials, non-ferrous metallurgy, steel, and chemical industries. With the development of the atmospheric environment service industry, the service subject has also developed from a single research and design unit to the current enterprise and research units. And with the increasingly comprehensive and specialized demands of environmental services, the comprehensive service industry of the atmospheric environment will become a breakthrough to broaden the coverage of the industry and promote the development of the industry to a higher level.
2.3 Analysis of the value chain of atmospheric environmental protection industry
According to the above analysis, the construction goal of the atmospheric environmental protection industry chain is to realize the value added, so the industrial chain and the value chain are closely connected, interact and influence each other. The atmospheric environmental protection industry chain forms a bottom-up pull-type consumption relationship. The downstream service chain is directly oriented to users and the market. It is a terminal that meets the needs of users. Its demand is to meet the national air pollutants total control, emission reduction requirements and Generated by the goal of atmospheric environmental protection, and then pass the demand to the middle and upper reaches. The realization process of its value is: when the upstream enterprises provide raw materials, parts and technologies to the middle reaches, the elements of their investment are transferred from the upstream enterprises to the middle enterprises, the upstream enterprises successfully realize the value, and the upstream enterprises absorb the upstream enterprises. Under the element, the production of air pollution control equipment and transfer to downstream enterprises or consumers to realize value, the downstream to purchase value by users to achieve value, is also the ultimate goal of the formation of the entire industry chain, the industry chain is based on this, the entire industry The most critical part of the value added of the chain.
With the increase of comprehensive air pollution control in China and the strengthening of multi-pollutant emission control, the market demand for air pollution control products and services is also increasing. Air pollution control products, engineering and services are national or even global products, and their market demand is not limited to the local market. The maturity of consumers in the air pollution control industry and the demand for related products and services will force the upstream, middle and downstream environmental protection enterprises to continuously strengthen innovation, improve product technical content and quality, improve service quality, and thus enhance competition in the entire industry. Advantages to promote the improvement of the entire industry chain.
Due to the complexity of the atmospheric environmental protection industry organization and the influence of market and policy factors, the realization of its value chain is a smile curve (Figure 2).
According to the atmospheric environmental protection industry value chain, its high-value link should be the front-end research and development of atmospheric environmental protection technologies and products, as well as the atmospheric environmental service industry. However, the current value-added of the atmospheric environmental protection industry is mainly reflected in the innovation and research and development of key equipment and agents. . In the installation of atmospheric environmental protection projects, environmental protection enterprises are basically free services, and subsequent maintenance and other services are basically free. Only some parts need to be replaced, and the value created is very small. Other types of services include air environmental protection engineering general contracting, etc. Because the state has higher requirements for service-oriented energy-saving and environmental protection enterprises, there are only a few companies engaged in it, and it has not yet produced good benefits. In addition, the atmospheric environmental protection industry has many sub-sectors, and the production, sales, and customers in different fields are very different. Therefore, the high-value links vary according to different sub-sectors, and need to be analyzed in combination with reality.
2.4 Classification of atmospheric environmental protection industry chain
According to the related factors between industries, the industrial chain can be divided into four types: technology-driven, resource-driven, demand-driven, and comprehensive linkage. The formation of the atmospheric environmental protection industry chain is a typical relationship that promotes the development of the middle and upper reaches with downstream demand, and belongs to the demand-driven industrial chain. The development orientation of the entire industry chain is clear, emphasizing user satisfaction. In addition, according to the type of sub-industry, the atmospheric environmental protection industry chain can be divided into the industrial chain of desulfurization industry, the industrial chain of denitrification industry, the industrial chain of dedusting industry, the industrial chain of automobile exhaust gas treatment industry, and the industrial chain of VOCs governance industry.
3 problems and optimization strategies
3.1 Analysis of existing problems
3.1.1 The development of the industrial chain is not balanced, there are still missing links and broken links.
The atmospheric environmental protection industry chain has problems of unbalanced and uncoordinated development of various links. If the investment in the upstream research and development of the industrial chain is insufficient, it will directly lead to air pollution control equipment, low technical content, low added value, and low efficiency; market-oriented service models such as atmospheric environmental protection infrastructure and thermal power plant flue gas franchise need to be improved, the atmosphere The public service platform for environmental protection industry has not yet been established and improved, and the development of atmospheric environmental protection service industry is still lagging behind, forming a pattern of strong middle and weak head.
From the perspective of the construction of the whole industry chain, there are still some links and broken links in the atmospheric environmental protection industry chain. For example, the current research and development of the VOCs for mobile sources and fixed sources, the development of the pollutant monitoring/detection technology and equipment, and the lack of manufacturing industries are lacking. Chain problem. In the field of motor vehicle and new energy vehicle prevention and control, due to the front-end prevention and control technologies such as fuel cells of new energy vehicles, the lack of research and development and manufacturing industries of back-end purification devices such as particulate matter capture, the industrial chain in this field is developing slowly. In addition, the entire atmosphere environmental protection industry chain field still lacks research and development of multi-pollutant collaborative control technology and equipment, and subsequent equipment manufacturing and services.
3.1.2 The technological innovation capability upstream of the industrial chain needs to be further improved
Although the upstream of the industrial chain, such as electric dust removal and bag dust removal technology, has basically reached the international advanced level, the desulfurization equipment has basically achieved localization, denitration technology and catalyst research and development have made positive progress, and the promotion of ultra-low emission integration technology for power plant flue gas has been affirmed, but with The gap between foreign technologies is still relatively large, especially in the key technologies of some key areas. For example, in the field of organic waste gas treatment, due to late start, the level of treatment technology is relatively low; in the technical fields of development and application of denitrification technology, control of toxic and harmful gases, control of pollutants in diesel vehicles, production of high-temperature filter materials, etc., it is still in the early stage of development and application; Heavy metal pollution, dioxins and other persistent pollutant control technologies are still in the early stages of research and development. Among the existing high-tech products, the proportion of independent intellectual property rights is still relatively low, and R&D investment is obviously insufficient. The status of the main body of enterprise innovation has not yet been established, and there are not enough enterprises with core technology and core competitiveness. Therefore, as the power source of air pollution control technology innovation, it still needs to be further improved in the future.
3.1.3 The comprehensive service capability of the downstream service chain is weak
As the atmospheric environment service industry is still in its infancy, and it is subject to the lack of key technologies in the middle and upper reaches of the industry chain and the lack of communication and cooperation between talents, knowledge and information, there are still many constraints on the development of the atmospheric environment service industry. The degree of socialization and specialization of the atmospheric environment service industry is low, the all-round service system is imperfect, and the marketization degree of the atmospheric environment service industry is low, which leads to the inefficient operation of China's atmospheric pollution control facilities, and has integrated integrated packaging and solving capabilities. There are fewer large-scale integrated environmental service companies. In addition, the atmospheric environmental information consulting service industry generally has problems of small scale and backward technical means, which makes the service network construction of atmospheric environment consulting companies and intermediaries unable to meet market demand, and the public service platform of atmospheric environmental service industry has yet to be established and improved. . It can be seen that China's atmospheric environmental service industry solves the comprehensive problem, and the ability to provide comprehensive services is still relatively weak and needs to be further improved.
3.1.4 The external environment of the industry chain needs to be improved
The external environment (including market mechanism, laws and regulations, policies, standards, etc.) of the development of the industrial chain directly affects the efficiency of the industrial chain. The external environment of China's atmospheric environmental protection industry chain still has the following problems: 1) The market supervision of the atmospheric environmental protection industry is not in place, the market competition is not standardized, the competition mechanism is not perfect, vicious competition exists; public-private partnership mode (PPP), third-party governance, etc. The market-oriented model, due to the unclear definition of the responsibilities of the government and the market, third parties and polluters, and the lack of corresponding stable legal guarantees, restricts the implementation of these market-oriented models in practice. 2) There is no systemic supporting fiscal, taxation and other policy systems, and the lack of innovation in the atmospheric environmental protection industry finance, the atmospheric environmental protection enterprises are facing difficulties in financing. 3) With the gradual liberalization of the market for atmospheric environmental protection industry, the threshold for entry into the market has decreased, and the standards of some industries have been lacking, resulting in many enterprises entering, but the scale of enterprises is generally small and the competition is scattered.
3.2 Atmospheric environmental protection industry chain optimization countermeasures
3.2.1 Strengthening technological innovation drive, speeding up the chain of links and chain extension
Promote technological independent innovation and research and development of the atmospheric environmental protection industry, and enhance the competitiveness of the atmospheric environmental protection industry chain. Guide and promote the technological innovation system that combines production, study and research with enterprises as the main body, and accelerate the introduction, digestion, innovation, integration and research and development of key core equipment and technologies for atmospheric environmental protection by relying on the special technology of major atmospheric environmental protection technology, and encourage the alliance of atmospheric environmental protection industry. The establishment of the industry chain to support the vertical enterprise to provide a total solution to meet the needs of air pollution control. The government has increased financial support for the development and promotion of advanced demonstration technologies, such as VOCs pollution prevention, NOx reduction in the cement industry, PM2.5 control and other key areas of atmospheric environmental protection advanced technology demonstration and promotion, and accelerate the promotion of more industries in China Preparation of best available techniques for pollution prevention and control.
Under the joint efforts of many parties, we will promote the improvement of the atmospheric environmental protection industrial chain, make up the lack of links, and extend the short chain. Accelerate the research and development of VOCs exhaust gas purification technology and equipment, focus on complementing the lack of chain in high-efficiency adsorption recovery, adsorption concentration, low-temperature plasma, etc.; expand the industrial chain of vehicle exhaust gas prevention and control, focus on breaking through NOx and particulate matter (PM) control technology, and accelerate Research and development of catalysts with low sulfur and durable precious metals; accelerate the industrial chain of multi-contaminant synergistic control, focus on research and development of high-concentration organic wastewater, sludge pollutants (high-toxic phenol, cyanide, ammonia nitrogen, tar, benzo芘, chloride) as a raw material for denitrification and mercury removal, instead of ammonia, urea and other agricultural fertilizer denitrification, mercury removal technology equipment; alkaline steel slag, calcium carbide slag for flue gas desulfurization, to achieve coordinated control of wastewater, solid waste and exhaust pollutants .
3.2.2 Improve the comprehensive service capability of the atmospheric environment service industry
We will improve and improve the policies and regulations of the atmospheric environment service industry and promote the development of different types of service industries. Improve the marketization, standardization, standardization and modernization level of atmospheric environmental engineering construction and operation, strengthen the training of professional talents in the atmospheric environment service industry, build a professional high-level team, and promote the development of the comprehensive service industry of the atmospheric environment. Enhance the specialization and comprehensive service capabilities of the atmospheric environment service industry, realize the extension of the industrial chain in the depth of the atmospheric environmental protection industry, and continuously explore new environmental service areas in the breadth and explore more environmental market demands.
3.2.3 Improve the policy and legal system and improve the external environment for the development of the industrial chain
Continue to increase the support of the central budgetary investment and financial funds to the atmospheric environmental protection industry, optimize the direction and mode of financial support, mainly used to cultivate advantageous atmospheric environmental protection enterprises. Moderately expand the scale of policy loans for the atmospheric environmental protection industry. Improve the market access system for atmospheric environmental protection industry, improve the qualification certification and franchise system for atmospheric environmental protection enterprises, strengthen supervision over the market, establish a fair and transparent market rules system, standardize the market order of the atmospheric environmental protection industry, and build and optimize the industrial chain. Provide a good external environment.
4 discussion
Based on the analysis of the characteristics of the atmospheric environmental protection industry, the concept of the atmospheric environmental protection industry chain is defined based on the theory of the industrial chain, and the characteristics and current status of the upper, middle and lower reaches of the industrial chain are analyzed. From the perspective of the number of enterprises, The number of enterprises in the upper, middle and lower reaches of the atmospheric environmental protection industry chain is inverted pyramid. From the perspective of development, upstream and downstream development, technology and product research and development continue to make new breakthroughs, but some key technologies are still mainly introduced; the middle reaches have a more competitive market, and the production of equipment covers the atmospheric environmental protection industry. The various sub-areas are an important part of the current value-added of the industrial chain; the downstream service industry continues to expand, but the comprehensive service capability still needs to be improved. In the analysis of the structure and development status of the atmospheric environmental protection industry chain, the countermeasures for improving and optimizing the industrial chain are put forward.
At present, the environmental protection industry has become a hot spot in academic research, but there are few studies on the atmospheric environmental protection industry, especially the atmospheric environmental protection industrial chain. The only scattered research has not analyzed the connotation of the atmospheric environmental protection industrial chain, and the definition of the industrial chain structure is not Clearly, the relationship between the industry chain and the value chain is rarely analyzed. By defining the concept and connotation of the atmospheric environmental protection industrial chain, this paper sorts out the industrial chain structure, and identifies high-value links on the basis of the analysis of the relationship between the industrial chain and the value chain, and puts forward suggestions for the development of different links in the industrial chain, in order to realize the atmospheric environmental protection industry. Chain optimization. However, the analysis of the atmospheric environmental protection industry chain focuses on the common research in the field of sub-sectors, and has not yet carried out detailed analysis on the characteristics of different fields. This will be the direction for further research in the future.
