Query: Influence of cognitive, geographical, and collaborative proximity on
  knowledge production of Canadian nanotechnology   Incorporating existing knowledge is vital for innovating, discovering, and
generating new ideas. Knowledge production through research and invention is
the key to scientific and technological development. As an emerging technology,
nanotechnology has already proved its great potential for the global economy,
attracting considerable federal investments. Canada is reported as one of the
major players in producing nanotechnology research. In this paper, we focused
on the main drivers of knowledge production and diffusion by analyzing Canadian
nanotechnology researchers. We hypothesized that knowledge production in
Canadian nanotechnology is influenced by three key proximity factors, namely
cognitive, geographical, and collaborative. Using statistical analysis, social
network analysis, and machine learning techniques we comprehensively assessed
the influence of the proximity factors on academic knowledge production. Our
results not only prove a significant impact of the three key proximity factors
but also their predictive potential.
