Abstract Based on the BCC model and Malmquist index, we measures the environmental technology innovation efficiency of southwest China from the cross section data and panel data respectively.The results shows that:Chongqing's overall efficiency of environment technology innovation is above the average, Guangxi, Guizhou, Yunnan are below the medium level, and Sichuan is in lower efficiency than chongqing.Its reason is the low of the scale efficiency and pure technical efficiency especially pure technical efficiency.Although our country environment technology efficiency increases each year, its average Malmquist index diminishes every year because innovation efficiency enhancement can not offset the impact of technology backward, Which means innovation output is not proportional to the input growth of investment
