Survey results on inter-voivodship diversity of the investment level in fixed assets of the private sector in years 1999–2007 are discussed in the article. Simple measures of the variation rank as well as investing intensity index were used in the analysis. An attempt of the voivodship ranking, based on current investment allocation, was undertaken. The results disclosure very important territorial disproportions and show predominance of Mazowieckie voivodship resulting from the capital potential of Warsaw. Other voivodships improve their positions. But within of next 10–20 years they have not too much chances to achieve the Mazowieckie voivodship's level.
