Abstract
China, as the world's largest developing
country and carbon emitter, faces numerous challenges in achieving the
"dual carbon" goals, and the environmental governance process will
inevitably have systemic impacts on the economy and society. This paper treats
the carbon trading pilot as a quasi-natural experiment, based on panel data
from 172 prefecture-level cities across the country from 2010 to 2022, and uses
a progressive difference-in-differences model to examine the impact and
mechanism of the carbon trading pilot policy on the urban-rural income gap. The
study shows that the carbon trading policy can narrow the urban-rural income
gap by increasing the level of non-agricultural employment among rural
residents. This conclusion remains valid after a series of placebo tests and
robustness checks, and the policy's effect is more pronounced in the eastern
regions and areas with a high degree of marketization. In light of this, this
paper proposes three policy implications: strengthen the coordinated governance
of carbon emissions and urban-rural income gaps, accelerate the construction of
a unified national carbon market; formulate policy measures according to local
conditions based on different regional endowment characteristics; and the
government should improve non-agricultural employment through multiple channels
to help narrow the urban-rural income gap.
