Dlaczego tak mało wiemy o wzroście małych i średnich przedsiębiorstw - subiektywizm w badaniach
PublikacjaRozwój przedsiębiorstwa jako przedmiot badań, doczekał się wielu opracowań literaturowych (patrz: Birch, Storey, Davidsson, Demar, Wiklund, Coad, Wasilczuk, Matejun itd.), jednak cały czas brakuje odpowiedzi na pytanie dlaczego małe firmy wzrastają i jakie czynniki na ten wzrost wpływają. Brak wiedzy na ten temat nie wynika z braku chęci badawczych, a raczej z nadmiaru problemów z takimi badaniami związanymi. Osoby prowadzące badania...
