Abstract:Based on the theory of low-carbon economy and industrial structure optimization, it is believed that technological innovation, industrial symbiosis, energy structure and environmental regulation drive low-carbon optimization of industrial structure, thereby constructing a realization mechanism model of low-carbon optimization of industrial structure, and the evaluation index system is constructed from three aspects of industrial structure advancement,rationalization and ecologicalization. The Projection Pursuit model (PP) based on Real Coded Accelerating Genetic Algorithm (RAGA) is used to comprehensively evaluate the low-carbon optimization level of China"s industrial structure from the two dimensions of time and space. Accordingly, some suggestions are given to improve the low-carbon optimization level of industrial structure.
