Entrepreneurship is multidimensional phenomenon and there is the lack of its uniform measure, in paper three were presented three single measures of entrepreneurship, the indicator of quality of firms' sizes, the indicator of quality of economic sector, the indicator of firms' saturation in economy, and one synthetic indicator, the indicator of entrepreneurial quality. In presented paper, the relationship between entrepreneurship's measures and the level of economic development in Polish regions was investigated. The influence of entrepreneurship, measured by single and synthetic indicators, on the level of regional development is positive. Better shaped structure of entrepreneurship leads to higher level of economic development. Among single measures, the indicator of quality of firms' sizes has the most important influence on the level of economic development.
