This paper makes an empirical research on the relationship between industrial enterprise heterogeneous characteristics and regional carbon intensity, based on the selection of panel data of industrial enterprises in China from 2007 to 2010. Results show that the scale and technical level of industrial enterprises have a significantly inhibitory effect on the carbon emission intensity, and employees have a positive effect on the carbon emission intensity, but there is no significant relationship between the enterprise benefit and carbon emission intensity. Further study finds that as far as enterprise scale and technical level are concerned, carbon emissions intensity is reduced by means of reducing energy intensity; The reduction of industrial enterprises staff can reduce the energy consumption intensity and energy emission intensity , thus playing a double role of energy saving and emission reduction to reduce carbon emissions intensity; The efficiency of industrial enterprises improve the expected economic output of unit asset, which is not very effective to restrain the output of non-expected carbon emission, and cannot reduce the carbon emission intensity.
