The article focuses on value models in entrepreneurship and, particularly, on a sustainable development perspective. In the first part, we show that the different economic models do not take the dimension of sustainable development into consideration. Indeed, they are principally concerned with the design of value, the production of value, or the valuation of value. The second part aims to put forward a renewed vision of models of value using the concept of complexity. To this end, we suggest taking several approaches, allowing us to link these three dimensions together. In fact, our goal is the integration of the sustainable development dimension in order to propose a global model of value. The article concludes by addressing the challenges that must be considered in order to grasp the meaning of value in a global way.
