This paper is about the curved space of economy. It shows that the space plane of economic diagrams could be analyzed through a curved space approach using the theory of equation transformations and graph changes. The curved space approach is determined by a finally weak positive economic dynamic of any economy, which shows that any economy has a physical positive dynamic independently from its condition. The physical condition of all economies is that they a have an initial decline and afterwards a positive condition. This is the reason why there is a curved space in economics, as physical condition. Even an economy in its worst version has a weak positive dynamic.
