Study on the Policy Diffusivity of China's Marine Strategic Science and Technology Power Building Based on LDA Modelling
Provisionally accepted- Zhejiang Ocean University, Zhoushan, China
The world's maritime countries are competing for the strength of marine science and technology. This paper employs a case study approach to examine the diffusion characteristics of China's marine science and technology policies. The analysis is based on the marine science and technology policies issued by the Chinese government at the central, provincial and municipal levels since 2002. The study employs an LDA model and text-mining techniques in the R language to construct a comprehensive understanding of the diffusion process. The study reveals that China's marine science and technology development policies exhibit a top-down diffusion trend. Furthermore, the implementation intensity and responsiveness of lower-level governments to higher-level policies are increasing. The diffusion of policy themes displays clear temporal characteristics, with policies undergoing continual refinement in the context of top-down content diffusion. However, there is less interaction between bottom-up policies.
