Abstract:As a creative cultural industry, the sci-fi industry is based on the creation and operation of sci-fi intel? lectual properties (IPs). Creativity connects it with other industries, generating corresponding sci-fi products, so it has the features of a horizontal industry. In today’s China, the market for sci-fi products is promising, but the industry still needs to be enlarged and its development demands support from various sectors. The nature of the industry determines that a megapolis or megacity with relatively complete industrial sectors is the most favorable environment for its expansion. Under current circumstances, developing the sci-fi industry is a feasible approach for a megapolis or megacity to transform and upgrade its urban industrial economy starting with a reform at the supply side.
