Why should China develop smart street lights and vigorously build smart cities?

According to statistics from the Ministry of Environmental Protection of China, in 2015, about 80% of the 338 cities monitored by the Ministry of Environmental Protection did not meet environmental protection standards. The country’s environmental pollution problem is quite serious, and haze is raging, which has caused great obstacles to the health and sustainable development of the people. In recent years, my country has also made a lot of efforts in energy conservation and environmental protection. From 2012 to the present, China has invested 384.7 billion U.S. dollars in clean energy such as wind energy and solar energy, maintaining a global lead. So far in 2016 alone, China’s new clean energy investment has reached 48.1 billion U.S. dollars, far exceeding Japan’s 9.6 billion U.S. dollars and the United States’s 32.6 billion U.S. dollars. my country is also vigorously guiding funds to invest in pollution reduction projects-smart street lights, and building smart cities. Since the government started the first batch of smart city pilot projects in early 2013, the construction of smart cities has been scaled up and included in the national development strategy. Ni Jiangbo, deputy director of the Department of Building Energy, Energy Conservation and Technology of the Ministry of Housing and Urban-Rural Development, said at the Barcelona Smart City Expo: To curb the bottleneck of urban development. Cities need sustainable development planning, using information, communication technology and perception to make intelligent responses to people’s needs.'
my country's development of smart street lights and smart city construction can on the one hand establish the image of a big country, and on the other hand, it can also help support my country's leading green industries. Mohan Munasinghe, the sharer of the 2007 Nobel Peace Prize, recently praised my country's pollution control measures at an international forum on impact investment at Wenzhou-Kean University.
