In constructing national corporate governance system it is very important to analyse market thoroughly and to adapt the system to the market conditions. The corporate governance is also discussed in Poland. The regulations adopted on Polish market are voluntary and are based on the Anglo-Saxon corporate solutions. There is a set of precise rules of behaviour addressing corporate bodies, their members and majority and minority shareholders. The measurement of observing rules enables us to compare different countries in their corporate governance. In the European Union there were several actions concerning capital market and corporate governance. 'Agenda Warsaw City 2010' also implies increasing capital market effectiveness by the 2010 as well as implementing further corporate governance rules.
