Abstract
Few paper notices the black side of trust on technology transfer. This paper utilizes the "Transaction Cost Economics" (TCE) to find out that trust, in some cases, can deter technology transfer between two manufacturing firms. Specifically, trust can influence the transaction cost through three dimensions, including "asset specificity", "transaction frequency" and "uncertainty", and then the relationship between trust and technology transfer can be detected with the help of transaction cost as a media. Finally, this paper finds out that before an optimal threshold point, the trust can decrease the transaction cost and, simultaneously, can improve the technology transfer. But after that, trust may increase the transaction cost, then imposing restrictions on the technology transfer.
