Innovation in Clean Coal Technologies: Empirical Evidence from Firm-Level Patent Data

Abstract: 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 affects 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.
