In modern neoliberal economy the independent of companies is very important because it develops and encourage economic growth in today’s westerns liberal democracies. The main part in economy have small and middle companies which are base-ground of economy because they make up the largest share of the number of companies in Croatia. By developing new technologies it shows up new forms of market manipulations and which represent a danger of new forms and ways of product falsification and common criminal activities that have a big influence on production and survival of companies.
