『Abstract
This paper examines the effectiveness of China's indigenous R&D
and technological innovation to curb its carbon emissions. The
mechanism of endogenous technical change (TC) is incorporated
an intertemporal computable general equilibrium (CGE) model/ R&D
investments and knowledge creations are modeled as the endogenous
behaviors or private firms. The accumulated stocks of knowledge
are applied in the production process to affect the rate and bias
of TC. Simulation results show that: (1) while China's indigenous
R&D efforts play a significant role to curb carbon emissions,
sole dependence on R&D may be far from sufficient to achieve
pledged climate target, with complementary policies being required
to reinforce existing climate actions; (2) innovation policies
can strengthen R&D investment and cut emissions further, but
the complementary effect is relatively minor; (3) carbon taxation
can generate significant carbon-saving benefits and fulfill climate
target, but this achievement is at the cost of economic losses.
The induced technical improvement, however, can partially mitigate
the deadweight loss incurred by carbon tax distortion.
