Overview

Panel data analysis reveals trends in marginal costs and their inequalities in China, suggesting policy adjustments.

Key Points

  • China's marginal carbon reduction cost declined and then rose, reflecting significant cost fluctuations over time.
  • The average marginal cost of carbon reduction shifted from 7.45 to a peak of 20.36 thousand yuan per ton between 2006 and 2019.
  • Inequality in carbon reduction costs decreased as the Gini coefficient fell from 0.220 in 2006 to 0.151 in 2019.
  • Policies promoting inter-city collaboration are essential for balancing carbon reduction costs across diverse economic regions.
