Abstract: Aiming at the fact that the R&D alliances between enterprises prevail nowadays but many of them have disintegrated before they came into expected effect, an analysis was made for the influence of trust on those R&D alliances via the game theory. With the concepts of trust and such R&D alliance ascertained, the influence of trust on the formation of such R&D alliances was discussed in relation to the three factors substitution rate of products, enterprise's learnability and rate of technology spillover. The results indicated that when the trust is firm, the enterprises ally with each other for R&D; when the trust is medium, either cunning or alliance is possible, depending on the three factors; when the trust is weak, an enterprise tends to do R&D individually.
