Although existing studies questioned the simple positive correlation between the technology transfer speed and the benefits, they have been widely condemned for lacking em-pirical evidence. Using the patent transfer data at the city scale in China, and distinguishing fast from slow by divid-ing technology transfer speed into four levels, this paper attempts to answer the question in terms of city economic growth, which is whether the faster is the better. Panel re-gression results show that for economic growth of city, the speed of technology transfer does not mean that faster is better. In other words, technology transfer maintaining a relatively rapid speed (more than 1 year and less than 2 years) can promote city economic growth, although the evidence is weak.
