Abstract: This paper applies an agent-based model to simulate the impact of different network structures on spatial diffusion of knowledge and regional technological progress. Main results are: 1) information network structures have a significant impact on both spatial information diffusion and regional technological progress; 2) information diffusion in networks is only imperfect, i.e., accumulated knowledge in regional networks correspond only to a constant fraction of technological knowledge generated in leader regions; 3) this fraction is c.p. higher for scale-free (SF) networks when compared to random and small-world network (SWN); 4) this fraction increased for SF networks with the preferential attachment parameter and for small world networks with the α-parameter; 5) in contrast to classical catch-up models our network approach to spatial diffusion of technological knowledge implies that except for extreme centralised or dense networks catching-up does not occur.
