“…Through this process, policy innovation spreads and is adopted among government, organizational, and other social systems over a certain period of time through specific channels of communication [19]. At present, based on theoretical research and empirical testing, scholars have summarized the internal and external factors that affect policy innovation diffusion [22] as including political factors [23], economic resources [24], and social development factors [20], as well as factors such as leader factors, conformity factors, competition factors, and information channel factors [25].
