| Summary: | This article empirically analyzes supply-side and demand-side factors expected to affect innovation in clean coal technologies. Patent data from 93
national and international patent offices is used to construct new firm-level
panel data on 3,648 clean coal innovators over the time period 1978 to 2009.
The results indicate that on the supply-side a firm’s history in clean coal
patenting and overall propensity to patent positively a↵ects clean coal innovation. On the demand-side we find strong evidence that environmental
regulation of emissions, that is, CO2, NOX and SO2, induces innovation in
both efficiency improving combustion and after pollution control technologies. |
