Extended data:
Environmental protection industry is a cross-industry, cross-field, cross-region, cross-field and inter-penetrating industry with other economic sectors. Therefore, some experts suggested that it should be listed as the "fifth industry" after the "knowledge industry".
Environmental protection industry has two kinds of understanding in the narrow sense and broad sense in the world. The narrow understanding of environmental protection industry is terminal treatment, that is, providing products and services in environmental pollution control and emission reduction, pollution cleaning and waste treatment, while the broad understanding includes clean technology and energy-saving technology in production, as well as product recovery, safe disposal and reuse, which is a green concern for products from "life" to "death".
According to statistics, the market size of global environmental protection industry has increased from $250 billion in 1992 to $600 billion in 20 13, with an average annual growth rate of 8%, far exceeding the global economic growth rate, and has become a "sunrise industry" that all countries attach great importance to.
According to the Twelfth Five-Year Plan for the Development of Energy Conservation and Environmental Protection Industry, by 20 15, the total output value of China's energy conservation and environmental protection industry will reach 4.5 trillion yuan, and the output value of environmental protection service industry will exceed 500 billion yuan, forming about 50 environmental protection service companies with an annual output value exceeding 100 billion yuan, with an average annual growth rate of 40%, and the service industry will account for 30% of the environmental protection industry.
This also shows that China's environmental service industry has more development potential.
