    Cluster as place of efficient diffusion of knowledge. Experiences of Lower Silesia by Malgorzata Wachowska

    Published 2019-06-01
    “…On the basis of the analysis of national and international patent applications, it has been found that few inventions of enterprises are created in cooperation with other cluster members as well as that enterprises refer to the knowledge of other cluster members in their patent descriptions to a limited extent, which in general does not support the thesis that cluster membership contributes to the intensification of knowledge-diffusion processes.…”
