Division of enterprises in the creation of Poland's GDP in the years 2004 - 2013
Open Research DataThe share of the SME sector in generating GDP is growing every year. Currently, all enterprises account for 73.5% of GDP. In 2004, this level was 70.5%. Bearing in mind the above, it is important to note the important role of both the entire enterprise sector in the role of the entire national economy and the micro-enterprise sector. As already mentioned,...
