The frequent occurrence of environmental problems in China has also attracted the attention of foreign media. Some media believe that the smog-like weather in many places in China has caused the suspension of some flights and the suspension of production of polluting enterprises. At the same time, it will also bring in clean energy vehicles and environmental protection industries. Opportunities are also an opportunity for the adjustment of China's energy structure and industrial structure.
The British "Financial Times" reported that the continued haze in Beijing was a disaster for certain industries. If smog was expanded, as many as 103 polluting enterprises were discontinued. It can be imagined that if the problem persists, the steel products in the surrounding provinces and cities in Beijing The development of the chemical industry will be seriously affected. The haze and air quality problems will force the government to speed up the adjustment of the industrial structure. Energy-saving and emission-reducing companies will get great development, and the prospects of heavy pollution companies are not optimistic.
According to the “Global Post†of Canada, hazy weather has caused China to suffer damages in the evaluation of commercial investment. Serious pollution has caused foreign-funded enterprises to hesitate when entering China. Many foreign executives are very concerned about air pollution in Beijing. This requires employers in China to increase job subsidies.
According to the San Francisco Chronicle, China is likely to raise the standards of automobile emissions, even to the most stringent EU standards, which will bring business opportunities to some technologically and consciously forward-looking companies. French Financial Network believes that hazy weather may bring a turn for the better in China's electric vehicle and photovoltaic industry, which has recently experienced bottlenecks in its development.
