research applies a Meta-frontier DN-DEA model, including the carbon reduction factor (CRF), to assess the emission efficiency … kinds of atmospheric pollutant emission elasticity coefficient and Kendall's coordination coefficient. The results are as …. YREB has great potential for carbon emission reduction, and the growth rate of its overall efficiency is higher than that …

without heterogeneity. We show that if firms have a constant emission share in terms of sales - as they do in a wide range of … trade and environment models - the three models' emission predictions exactly coincide. Conversely, if firms have a constant … emission intensity per quantity - a prominent alternative in the literature - the emission equivalence between the three models …
