Facing the international controversy about the regional scale emission of Chlorofluorocarbons( CFCs) ,the main gases,CFC -11 and CFC -12,caused by industrial production in China were analyzed. The research progresses on CFCs in key areas of China and the occurrence of CFCs were discussed. The progress of CFCs elimination by the Chinese government was summarized. The analysis showed that around 2011 and 2016, the decline of CFC-11 and CFC-12 concentrations in atmosphere slowed down. Their concentrations even increased abnormally. The elimination progresses in East Asial agged behind the world's average,and its decline rate fluctuated greatly. Since 2000, the decline rate of CFCs in China had been ahead of other countries in East Asia. However, after 2015, the decline rate in China slowed down significantly, and the concentration even increased. Although the elimination process of CFCs in China has entered the middle and late stage, strict supervision is still required. There are many influencing factors of atmospheric environmental pollution, which should be comprehensively evaluated in combination with the development status and governance efforts of each country.
