A system dynamics model connecting carbon emission reduction, green industrial growth and green financial development is constructed。The simulation analysis shows that, under the condition of maintaining a certain economic growth rate, the realization of the "double carbon" goal is a positive feedback process in which the proportion of non-fossil energy continues to rise and the efficiency of industrial low-carbon development continues to improve. The industrial growth effect of green finance is to mobilize multiple financing entities to participate in and promote this process, support the advanced construction of infrastructure for green transformation, the incremental growth of new industries and the innovation activities of green economic entities. Promoting the synergy between green finance and industrial development, and building a new market ecology that connects industry, finance and residents, can carry the formation of new carbon asset trading and ecological product pricing mechanism, guide green consumption concepts and behaviors, expand green market demand, and create a large-scale market space for the growth of green low-carbon industries.
