Abstract

This paper is a pioneer study which examines the innovation of renewable energy generation technologies based on residential patent applications in 30 regions of China between 2006 and 2015. Wind power, solar energy, geothermal energy, ocean energy, hydro power, and biomass & waste energy are the subject technologies for this analysis. Different indicators such as absolute numbers, growth rates and revealed technology advantages are used to measure the various green innovation dynamics in different regions. The results show that some regions with a higher number of patent applications or growth rates did not show stronger technological advantage (specialization) in such technologies. On the other hand, the region of Inner Mongolia shows a very strong specialization but with a much smaller number of patent applications.
