R&D Competition Efficiency with Network Externalities |
| |
| Abstract: | In order to analysis the effect on R&D competition stratedies of network externality, a concept of external revenue is proposed to establish the dynamic R&D competition model with R&D externalities. Conclusions are made that the network externalities reduce the enterprise's investments in R&D, therefore, the R&D competition rate should be controlled and the R&D incentives from the government should be enhanced. Furthermore, the optimal number of the enterprises is 3 in the network economic industry for the R&D competition to be efficient. |
