Abstract: The study views the structure of an organization’s human intellectual capital that integrates both employee’s intellectual, professional and personal abilities to perform innovation activity and their results achieved in the process of this activity. We prove the role of human intellectual capital in improving an organization’s innovation activity. Basing on the cost, income, expert-based and psychological approaches, the article develops the intellectual capital monetary valuation model focused on increasing the objectivity of measuring its value by taking into account individual intellectual and performance characteristics. The application of this model aims to activate the innovative development of social and economic entities by increasing the quality and effectiveness of human intellectual capital.
