In China, the manufacturing industry of environmental protection equipment can be divided into three categories: manufacturing of special equipment for environmental protection, special instruments for environmental monitoring and special pharmaceutical materials for environmental pollution treatment. At present, air pollution control equipment, water pollution control equipment and solid waste treatment equipment have formed a certain scale and system.

1. Current Situation Analysis

     In recent years, driven by relevant policies, the market demand for environmental protection equipment in China has been growing again. Dust removal equipment, coal-fired flue gas desulfurization equipment, municipal sewage treatment equipment continue to sell well. Domestic waste treatment equipment and desalination equipment also grow rapidly. The 12th Five-Year Plan of Environmental Protection Equipment in 2012 clearly states that the total output value of environmental protection equipment industry will increase by 20% annually and reach 500 billion yuan in 2015. In 2014, the "Implementing Plan for Industrialization of Major Environmental Protection Technological Equipment and Products" formulated by the Development and Reform Commission, the Ministry of Industry and Information Technology, the Ministry of Science and Technology, the Ministry of Finance and the Ministry of Environmental Protection calls for the realization of an industrial gross value of environmental protection equipment of 700 billion yuan by 2016. In October 2017, the Ministry of Industry and Information Technology studied and formulated the Guiding Opinions on Accelerating the Development of Environmental Protection Equipment Manufacturing Industry. The Guiding Opinion clearly states that by 2020, the output value of environmental protection equipment manufacturing industry will reach 100 billion yuan. In addition, from 2011 to 2016, the total profit of environmental protection equipment industry increased from 108.769 billion yuan to 239.281 billion yuan, and only declined in 2015. The remaining years achieved year-on-year growth, reflecting the good business situation of the industry.

2. Existing problems

    Although China's environmental protection equipment manufacturing industry is developing well, there are still some problems. The first problem is still that the industry leader is not obvious, and the overall situation is "small, scattered, chaotic". According to the annual report of environmental protection equipment enterprises, most of them have no more than 100 million revenue, and the top ten enterprises have no more than 5% share in the whole environmental protection market. They are lagging behind water treatment enterprises in terms of scale and reputation. Secondly, core technology is the key. Independent innovation and technological R&D need to be improved. The poor R&D conditions, lack of experience and weak team, some key equipment and core components are constrained by others, which are the key factors restricting the development of environmental protection equipment industry.

3. Future Trend Direction

    However, after nearly 30 years of development, the situation of "more and weaker" and "smaller and scattered" environmental protection industry in China is changing rapidly, and the level of environmental protection technology and equipment has been significantly improved: the technology level of environmental protection equipment such as membrane bioreactor, high-pressure filter press has reached the international leading level, dust removal and desulfurization, urban sewage treatment and other equipment supply energy. Leading in the world, the value-added of waste products is constantly increasing, showing high-value, refined characteristics. With the vigorous support of the national environmental protection policy and the increasing investment in environmental protection, the scale of environmental protection equipment industry in China will continue to expand, and the market space will continue to expand. It is expected that the output value of environmental protection equipment industry in China will exceed 950 billion yuan by 2023. Secondly, the technology level has been greatly improved. In the future, the industry will aim at breaking through the key common technology, rely on the key common technology of the industry, take the industrial chain as the link, cultivate and create the technology innovation center and the industrial technology innovation alliance. We should guide enterprises to innovate synergistically along the industrial chain, promote the formation of synergistic innovation community, achieve precise research and development, and conquer a number of key technologies, equipment and materials and pharmaceuticals for pollution control. Differentiation, agglomeration and integration development. Leading enterprises will develop into integrated service providers integrated with system design, equipment manufacturing, engineering construction, commissioning and maintenance, operation and management, while small and medium-sized enterprises will develop into "specialty and specialty" oriented by product specialization, R&D deepening, service specialization and new-type industry, forming a group of small and medium-sized enterprises led by leading enterprises. The agglomeration area of industry matching and coordinated development of industry chain.

    Finally, expand the international market. Environmental protection equipment enterprises will participate in engineering construction and operation by means of technology introduction, cooperative research and development, and direct investment. They will take the form of complementary advantages and strong alliance to actively expand foreign markets and achieve international docking.
