The problem of spatial injustice runs through the history and current of urbanization under the background of globalization due to the capital logic and political nature of modern urban space production, and will continue to the future inevitably to become an important perspective of urban critical discourse. And the imagination of future cities in science fictions highlights this problem through the dimension of technology, and forms intertextuality and tension with the real cities. By the way of technological imagination in science fiction, the radical production of urban spectacles and representation of spatial injustice lead to the revolt narrative to show the path of space political struggle. This paper takes works such Metropolis, Elysium, and Snowpiercer as examples, which represent the spatial injustice in future in sci-fi cities directly by radical production of technological spectacles include vertical opposition, drift isolation, horizontal concentration and others, and which then launch different patterns of revolt narratives and discourse strategies. But by following the logic of cultural consumption, these works tend to simplify the spatial injustice and the resistance to it by taking binary opposition as the model.
