Paris has a history of more than 800 years as the capital of France. In the middle of the nineteenth century, Napoleon III and Georges Haussmann implemented the urban transformation of Paris, that started the capitalism construction of the capital of modernity, and had impacted Paris and the global urban development continues to this day. After more that a century, François Mitterrand’s government in the 1980s built up "The Grands Projets" in Paris as the monumental buildings for the French Revolution, becoming important symbolic national architectures to show the creativity of the French modern capital. This paper attempts to examine and explain the the above two cases of urban transformation, from the perspective of space production, to explore both of the spacial power allocations, Paris regeneration of Haussmann and "Les Grands Travaux" of president Mitterrand, highlighting the differences between the two urban plan concepts; additionally, to expose how the influence and historical mechanisms and social mechanisms affected the urban spatial practice, the representations of space, and the representational space of Paris in different historical times.
