Over the past weekend, Beijing city has been hit by smog. Anbound's chief researcher, Chen Gong, points out that, the smog in Beijing can be used as an indicator to judge the economic growth in China. If there is many smoggy days on a particular year, then the economic growth for that year will be over 7%, or else it will be less than 7% Chen Gong suggests that the China’s economic policy should be divided into two parts, the policy for the western region and the policy for the eastern region. Or alternatively, the policy system should be divided into the "developed economic zone" and “developing economic zone”. China should not continue its one-size-fits-all approach.
