This article makes a distinction between two types of entrepreneurship activities --Venture Entrepreneurship (VE), which deals with new venture creation, and Innovation Entrepreneurship (IE), which involves innovations within existing enterprises.VE is found to be positiviely related to GDP growth rate.IE is negatively related to economic growth rate in high-income countries, while the findings for middle- and low-income countries are mixed.The study contributes to a relatively sparse body of literature by exploring the nature of the relationship between entrepreneurship and economic performance.
