In recent years, there has been a growing awareness that innovation plays the key role in the success and the functioning of organizations. This publication reveals an interdisciplinary dimension, because it addresses the increasing need for sustainable innovation that combines economic, environmental and social elements. Its aim is to present the international exchange of ideas, research results and practical experience in the field broadly understood as innovation, to highlight the importance of innovation management in a competitive, global economy, and to discuss the current problems related to innovation and entrepreneurship. In the economy reliant on innovation of various organizations, cross-sectoral co-operation is of paramount importance. It allows to achieve synergy between entities with diverse resources and competences in generating innovative projects. Originally, analysis of cross-sectoral relations focused on building links between business and science - in particular, the realms of research and development. This is the most obvious system by means of which the economy is fed with innovative concepts and their implementation solutions. Over time, the public sector too has begun to be perceived not only as an entity that creates economic regulations, but also as a real partner in the process of shaping economic development: it provides innovative projects, which are then commercialised in business. Therefore, the role of the public sector is not only to legislate, but also to conduct joint actions with the innovative business sector in order to stimulate local development of innovative projects. This publication will address the so-called triple helix (the most effective process of generating innovation): the system of co-operation between business, science, and government that contributes to the creation of innovative economy.
