    "abstract": "In this study we consider relations between companies in Poland taking into\naccount common branches they belong to. It is clear that companies belonging to\nthe same branch compete for similar customers, so the market induces\ncorrelations between them. On the other hand two branches can be related by\ncompanies acting in both of them. To remove weak, accidental links we shall use\na concept of threshold filtering for weighted networks where a link weight\ncorresponds to a number of existing connections (common companies or branches)\nbetween a pair of nodes.",
