Abstract:

The difference in the contribution of industrial structural upgrading to energy efficiency needs to be studied from the structural evolution direction as different directions have different influences on energy efficiency. We decomposed the structural evolution direction into two dimensions of industrial structure rationalization and industrial structure optimization,rebuilt the industrial structural upgrading evaluation index on the basis of factor productivity of labor and capital,and analyzed the effects of industrial structural upgrading on energy efficiency and its growth rate using regular,growth and elastic models. We found that the industrial structural evolution direction has a significant influence on energy efficiency and its growth rate;the improvement in energy efficiency is mainly because of optimization of industrial structure,while a decrease in rationalization level inhibits improvements in energy efficiency and its growth rate. The expansion of the gap between the two directions of industrial structural rationalization and industrial structural optimization is likely to lead to further negative effects to energy efficiency and its growth rate. The rise in the proportion of clean energy in energy consumption structure has a positive effect on improving energy efficiency and its growth rate. Therefore,we believe that the future trend of industrial policy should be to change the status of irrational industrial structure,reduce its inhibitory effect on energy efficiency,and narrow the gap between industrial structural rationalization and optimization. The tendency of future energy policy should improve the proportion of clean energy consumption and substitute energy inputs from natural and other clean energy sources to promote energy efficiency and its growth.
