The effects of industry characteristics on the sources of technological product and process innovation

In order to explore the effects of industry characteristics on the sources of technological product and process (TPP) innovation, this paper considers various sources in a united framework, and identifies their cross-industry similarities and differences. It sheds light on three Chinese high technology industries, and empirically confirms that in-house R&D, technology transfer, technology spillover and back-propagation of user innovations are all effective sources of TPP innovation. However, each source creates different productivity in different industries, which may be explained by the following industry characteristics: the dependence on foreign technology, the importance attached to inventive in-house R&D, the level of domestic technology, the relative proportions of foreign and domestic users.
