In the 21st century, the global environmental protection industry has begun to enter a stage of rapid development, gradually becoming an important force to support the growth of industrial economic benefits, and is becoming an important goal and key for many countries to reform and adjust industrial structures. Environmental protection industries in the United States, Japan, and the European Union have become major players in the global environmental protection market.
With the continuous and rapid development of China's economy, the urban process and industrialization process continue to increase, environmental pollution is becoming increasingly serious, and the country attaches greater importance to environmental protection. During the 10th Five-Year Plan period, as the state increased investment in the construction of environmental protection infrastructure, it effectively stimulated the market demand for related industries. The overall scale of the environmental protection industry expanded rapidly, the industrial field continued to expand, the industrial structure was gradually adjusted, and the industrial level was significantly improved.
Under the requirements of the development of a circular economy, environmental protection expenditure subjects have been formally included in the national budget since 2007. The government has proposed new ideas and new countermeasures for environmental protection work. Benefiting from this, China's environmental protection industry continues to grow at a high speed, and the growth rate is further improve.
In 2007, China adopted comprehensive measures to promote pollution reduction. The proportion of coal-fired generating units equipped with desulfurization facilities in the country's total thermal power units increased from 12% in 2005 to 48%, and the urban sewage treatment rate increased from 52% to 60%. Annual national COD emissions were 13.833 million tons, a decrease of 3.14% compared to 2006; sulfur dioxide emissions were 24.681 million tons, a decrease of 4.66% compared to 2006. The discharge of major pollutants achieved a double decrease, and the first “inflection point” appeared. Pollution The prevention and control has shifted from passive response to active prevention and control. The historic change in environmental protection has taken solid steps.
In 2008, the state required the shutdown of 13 million kilowatts of small thermal power, the elimination of a large number of backward production capacity such as 6 million tons of steelmaking, 50 million tons of cement, and 14 million tons of ironmaking, reducing 600,000 tons of sulfur dioxide emissions and reducing chemical oxygen demand emissions. 400,000 tons. Demand for environmentally friendly products and services has further expanded. In the first half of 2008, total national COD emissions were 6.742 million tons, a year-on-year decrease of 2.48%; total sulfur dioxide emissions were 12.133 million tons, a year-on-year decrease of 3.96%, and 6.67 million tons / day of new urban sewage treatment capacity was added. In the second half of 2008, affected by the US financial crisis, in order to expand domestic demand, China increased infrastructure construction on a large scale, and investment in environmental protection industries also increased.
China's environmental protection industry is still at a stage of rapid development, the overall scale is relatively small, and its boundaries and connotations are continuously expanding and enriching. With the development of China's social economy and the adjustment of the industrial structure, the direct contribution of China's environmental protection industry to the national economy will change from small to large, and gradually become an industry that improves the quality of economic operations, promotes economic growth, and improves the level of economic technology. The direction of industrial connotation expansion will mainly focus on clean technologies, clean products, and environmental services. The concept of China's environmental protection industry will also evolve into: "environmental industry" or "green industry".
During the "Eleventh Five-Year Plan" period, China's environmental protection industry is expected to maintain an average annual growth rate of 15% -17%. The key areas of environmental protection investment include water environment, atmospheric environment, solid waste, ecological environment, nuclear safety and radiation environmental protection construction. And environmental capacity building. In 2010, the total annual income of the environmental protection industry will reach about 880-1 trillion yuan, of which the output value of comprehensive utilization of resources is 660 billion yuan, the output value of environmental protection equipment is 120 billion yuan, and the output value of environmental services is 100 billion yuan.
1. Industry's upstream and downstream industries
Environmental protection water treatment industry upstream includes water treatment agent, water treatment equipment, pump and valve products, building materials and other industries. Downstream industries include municipal, power, metallurgical, petrochemical, and papermaking industries.
2. The impact of upstream and downstream industries on the industry
The prices of water treatment agents, water treatment equipment and materials, electrical equipment, and building materials in the upstream industry will directly affect the cost of the water treatment industry and affect the profits of enterprises in the industry.
Increasing demand and prices in upstream industries will increase the operating costs of the water treatment industry and adversely affect the water treatment industry. Conversely, intensified competition and lower prices in the upstream industry will increase the profit of the water treatment industry and have a beneficial impact on the water treatment industry.
The strength of the downstream industry's investment in water treatment systems will determine the needs of the water treatment industry. If the downstream industry develops rapidly and the demand for water treatment systems increases significantly, it will drive the development of the water treatment industry and increase the total profit of the water treatment industry. Conversely, if the downstream industry starts to stop investing in water treatment systems, it will reduce the demand of the water treatment industry and reduce the total profit of the water treatment industry.
With the improvement of national environmental protection and the continuous progress of technology, the downstream industry will put forward new requirements on the design level, construction technology, and construction materials of the environmental protection water treatment industry, which will enable water treatment companies to continuously research and develop new technologies and apply new processes. To adapt to changes in market demand.
