With the development of China's social economy and the adjustment of its industrial structure, the direct contribution of China's environmental protection industry to the national economy will grow from small to large, and gradually become an industry that improves the quality of economic operation, promotes economic growth and improves the level of economy and technology. The direction of industrial connotation expansion will mainly focus on clean technology, clean products, environmental services, etc. The concept of China's environmental protection industry will also evolve into 'environmental industry' or 'green industry'.
