Two-stage signaling game model on R&D decision-making of vertical industrial groups

In order to study the optimal R&D strategies of industrial groups in dynamic environment, this paper sets up a vertical group model on two stage R&D decision making by employing signaling games, based on Schumpeter's process of creative destruction. The model is a synthesized endogenous growth model that incorporates two category models in the new growth theory that are Capital based models and Idea based models. It gives the optimal R&D and capital investment strategies for the member firms of group. It can follow from the model that the larger is the innovation size of upstream firm, the smaller the optimal innovation size of under stream firm is, and the larger is the innovation size of the stage one, the smaller the optimal innovation size of the stage two is.
