China's total-factor energy efficiency fluctuated from 2003-2016, with industrial structure adjustments and technological innovation output boosting efficiency. However, innovation input showed limited impact due to poor conversion rates.
Area of Science:
- Environmental Science
- Economics
- Energy Policy
Background:
- Improving energy efficiency is crucial for sustainable development.
- Industrial restructuring and technological innovation are key drivers for enhancing energy efficiency.
Purpose of the Study:
- To measure China's total-factor energy efficiency (TFEE) using a modified Super-SBM method.
- To analyze the impact of industrial structure and technological innovation on TFEE using a dynamic spatial panel model (DSPM).
Main Methods:
- Modified Super-SBM method for measuring TFEE.
- Dynamic spatial panel model (DSPM) for impact analysis.
- Analysis of data from 2003 to 2016.
Main Results:
- China's TFEE showed a "falling first, then rising" trend between 2003 and 2016, with an inflection point in 2012.
- Eastern China's TFEE significantly exceeded the national average, while Central and Western regions lagged behind.
- Inter-industry structural adjustments and intra-industry productivity growth positively impacted TFEE.
- Technological innovation input had an insignificant effect, contrasting with a significant positive impact from innovation output.
Conclusions:
- Industrial restructuring and technological innovation output are vital for improving China's TFEE.
- Addressing the low conversion rate of scientific and technological achievements is critical for maximizing innovation's impact on energy efficiency.
