【Abstract】 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 economic 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 economy-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 cities",and"NON environmentally friendly development cities".The improvement level of per capita 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.更多还原
