Innovative People : Mobility of Skilled Personnel in National Innovation Systems The mobility of qualified labour between and among the public and private sectors is a vital mechanism for diffusing tacit knowledge within local national and global innovation systems.

It also documents the rapid internationalisation of this form of knowledge flows and provides guidance for the improvement of internationally comparable statististics in this area. FURTHER READING.
