Research on Asymmetric RD Investment Evolution

摘要

This paper studies asymmetric R&D/product problem. By comparing the results of one synchronize and two sequence games in various stages through an industry's evolution process, which reflect by the ratio of technology spillovers to product substitution, we conclude that endogenous sequence game is the optimal choice and along with the evolution of industry it will switch to synchronize game. This result can explain the scene of asymmetric R&D investment in open developing countries and predicts the law of R&D investment evolution.
