In this paper, the entropy weight method and fuzzy comprehensive judgment model are combined with the evaluation index system of cultural development of film and media and digital cultivation of talents to realize the measurement of the level of cultural development of film and media and digital cultivation of talents. The coupling coordination degree model is used to calculate the coupling coordination degree between cultural development and digital cultivation of talents, and Dagum Gini coefficient, kernel density estimation and convergence test are used to explore the reasons for the differences in the coupling coordination degree between cultural development and digital cultivation of talents, the distribution characteristics, and the convergence. The results of the study show that the mean value of the coupling coordination degree between cultural development and digital cultivation of talents in Guangdong, Hong Kong and Macao Greater Bay Area ranges from 0.466 to 0.501 from 2013 to 2023, and shows a fluctuating and slowly increasing trend. The average contribution of intra-group gap, inter-group gap and hypervariable density in the three metropolitan areas of Guangzhou-Foshan-Zhaoxing, Shenzhen-DongguanHuizhou and Zhuhai-Zhongjiang are 28.676%, 40.102% and 31.221%, respectively, and the inter-group gap is the main factor contributing to the difference in the coupling coordination degree of the three metropolitan areas. Meanwhile, the convergence of the coupling coordination degree of the Pearl River Delta and the three metropolitan areas is good, and improving the coordination between cultural development and digital cultivation of talents in cities with low levels of coupling coordination degree can effectively narrow the gap between them and cities with high levels of coupling coordination degree.
