Abstract: | In this paper the process of knowledge accumulation for a particular technology is studied. Two countries, say the technology
follower and the technology frontier, are considered. The frontier’s knowledge growth is determined by its R&;D efforts on
the technology. The level of knowledge stock for the follower country is augmented by its R&;D activities for the technology
and absorbing some of the external knowledge through spillover from the frontier. The extent to which the follower is able
to exploit the external knowledge depends on technological gap, absorptive capacity, absorption time and degree of spillover.
New concepts such as natural and enhanced degree of spillover, background and innovative knowledge and absorption speed are
introduced in the present work to deeply explore the process of knowledge spillover. The factors influencing the knowledge
development in the long term are simultaneously studied in an integrated structure provided by the System Dynamics approach.
This framework shows the responses to the changes and provides the basis for examining the interactions among the variables
over time. |
