This work surveyed and analyzed the GDP per capita and air quality synthesis index of Chinese 31 provincial capitals and municipalities in 2013 and 2014,and compared the level of e-conomic development of these cities from the environment-friendly view.Results show there is a negative relationship between per capita GDP and air quality among these cities,that is,the cities with higher per capita GDP may have relatively worse air quality.This observation implies that e-conomy-oriented development mode may bring about some environment costs.According to 2014 data,the 31 provincial capitals and municipalities are respectively evaluated as “environmentally friendly development cities”,“economy-oriented development cities”,“environment-friendly cit-ies”,and “NON environmentally friendly development cities”.The improvement level of per ca-pita GDP and air quality among these cities in 2014 is also compared with 2013.These findings could provide some supports for implementing the economy-oriented development mode.%根据中国31个省会及直辖市2013年和2014年的人均 GDP 与空气质量综合指数数据,考量各城市经济发展水平。结果发现:主要城市人均 GDP 与空气质量具有一定的负相关性,表明以经济为主导的发展模式可能会带来一定的环境问题。
