Abstract: This article uses the CEPII-BACI database，Chinese industrial enterprise database，China Customs data，Chinese industrial enterprise pollution database to constitute panel data of Chinese export manufacturing enterprises from 2000 to 2010 and carries out a detailed study on the impact and mechanism of external market demand on the environmental performance of Chinese manufacturing enterprisesResearch conclusions show that: the increase in external market demand will promote enterprises' comprehensive pollutant emission intensity and CO2 emission intensityThis effect is mainly due to the expansion of enterprises coaldominated energy input caused by the increasing external market demand，while the external demand has not induced the enterprises' green innovation effect to improve the environmental qualityHowever，the external demand will promote the “clean” development of the enterprises' export product structure，which is conducive to the improvement of corporate environmental performanceIn addition，the expansion of external demand has a greater impact on the environmental pollution emission intensity of enterprises in areas with low economic development level，of enterprises in capitalintensive industries，and of enterprises whose main export targets are developing economies

Key words: external market demand, comprehensive pollutant emission intensity, CO2 emission intensity, energy input, the adjustment of export product structure
