In this reference book, the author calls upon the actors of the decision-making poles and the economic agents on the need to define new strategic axes that will allow to guarantee not only the economic growth in several countries, but also a more ecological environment, relying on an ecosystem that encourages an inter-sectorial collaboration during the large-scale sports and cultural projects.The author demonstrates how, starting from a sports event and an innovative business model, it is possible to drive local and sustainable development, with the participation of key development actors.The role of the household economic agent is redefined within a financial and social ecosystem that is systematically linked to the interactions between the different economic agents and to a Digital Payment Market platform.With this new approach to structural development, the construction of social welfare enters a new dimension.
