Abstract: | The paper deals with institutional change in Poland. The accompanying pherlomenon is an escalating wave of entrepreneurial ventures. They take on different legal forms. The most popular, limited liability companies, emerge in the private, the cooperative, and the state sectors, and often across these sectors. These developments give rise to new interest groups which generally support a market reform. The conflict between the market oriented sector and the administered sector becomes one of the main factors influencing the economic policies of the state. In the paper, the development of the private sector is analyzed with the use of measures relating to the proportion of revenues from the private sector in the total state budget revenues. |
