Abstract:In order to further promote the development of digital creative industry in the Yangtze River Delta region, an innovation ecosystem model of digital creative industry in the Yangtze River Delta region is constructed using system dynamics. The model consists of three subsystems, including supply, demand, and support factost subsystems. By designing five simulation schemes, this paper discusses the influence of enterprise, demand, government, environment and service organization on system operation. The results of the study show that different programs and implementation efforts have different effects on system operation. The independent innovation program has the best effect in promoting system operation, followed by the service catalysis, decentralization promotion and government guidance programs, and the demand-pull program has a weaker promotion effect. The findings of the study can provide valuable insights for the digital creative industry in the Yangtze River Delta region to achieve high-quality development.
