What makes it open: factors affecting the openness of power equipment manufacturing firms in open innovation

We have taken a study to assess the factors that affect the extent of that firms introduce resources from the external. We have factors of firm size, R&D capability, absorptive capability, need for knowledge, need for complementary assets, the opening culture and the technology protection institutions based on related literature. We have taken a regression analysis in two types of openness as dependent variables based on a sample of 219 firms in the Chinese power equipment manufacturing industry. Result shows that the firms in the sample have to take special means for external technologies and complementary assets with limited capabilities and technology accumulation, which is different from that in developed countries. We have presented some propositions for firms to improve the technology and resources accumulation efficiency in terms of adjusting the openness.
