Fig 10 — Carbon intensity decomposition analysis of industries (20%<growth rate≤30%)There are fourteen industries with carbon intensity growth rate larger than 30% and smaller than or equal to 40% (see Fig. 11). Industries in this carbon intensity range has the largest amount, accounting for more than 25% in total industries. To be more specific, there are ten industries with carbon intensity growth rate in the range of 35% and 40%. Energy intensity significantly accelerates carbon intensity decrease for all industries except industry O84, where energy intensity presents a negative impact on carbon intensity decrease. As for the energy mix effect, most industries see a carbon intensity decrease except the industry C16 and industry K66. As the discussed industries, energy mix has a slightly weaker effect on carbon intensity change than the energy intensity. However, industry C33 is an exception, whose energy intensity decreases by 38.62% for the period of 2000–2014, on the other hand, energy mix (−21.15%) has a slightly stronger effect on energy intensity (−17.47%). In addition, energy intensity (48.46%) has a negative impact while energy mix (−79.86%) has a positive and more significant impact on carbon intensity change for industry O84, whose carbon intensity decreases by 31.4% during the whole period.
