Abstract: This paper is based on the manufacturing industry panel, dividing industry heterogeneity depends on the pollution emission intensity, using the DDF measures the manufacturing industries’ environmental efficiency in consideration of energy inputs and undesirable outputs, and then we construct SYS-GMM and panel threshold model to test the relationship between environmental regulation and environmental efficiency, the studies show that: ①The environmental efficiency of manufacturing industry presents rising trend, but which is significantly lower than the estimated results without considering resources inputs and environmental negative output. The environmental efficiency level shows obvious industry heterogeneity.②Environmental regulation significant improves the manufacturing industries’ environment efficiency, the effects of environmental regulation on moderate pollution and slight pollution industries’ are positive, while in heavily polluting industries, the effect is negative.③There are three threshold effects between environmental regulation intensity and environmental efficiency, and presents the nonlinear features of the "U" type, and the threshold effects are different among different types of industries.
