2022年全球能源危机是否加速了低碳技术的扩散？

This Policy Research Working Paper 10777 examines the diffusion of low-carbon technologies in 35 countries from 2019 to 2022. The study uses text analysis of job postings and earnings calls transcripts to measure the diffusion of a comprehensive range of low-carbon technologies. The results show a rapid acceleration in the diffusion of low-carbon technologies in 2022, driven by technologies related to renewable energy, vehicles, thermal performance, and electrical generation and storage. Rapid growth occurred in three quarters of the countries studied and 228 of 300 subnational regions, although was fastest in the fourth quarter. The study also documents the role of government policies and investments in promoting the diffusion of low-carbon technologies. Overall, the findings suggest that the 2022 global energy crisis accelerated the diffusion of low-carbon technologies.
