Fig. 7: Heterogeneity results of firms of different size.

a denotes the impact of BCP on firm energy efficiency in different size. The different colors of the bars denote energy efficiency of SMEs and Large firms. b denotes the impact of BCP on firm energy consumption in different size. The different colors of the bars denote energy consumption of SMEs and Large firms. In addition, the direction of the bar denotes whether the impact of BCP is positive or negative. The line segment on the bar denotes the standard error of the impact. If the line segment does not intersect the x-axis, it denotes that the impact is significant.
