Abstract:

Based on the theory of policy diffusion， the diffusion process of government information transparency system of 31 provincial governments and 49 larger city governments was explored. It was found that the local government information transparency system has a significant diffusion effect， with its diffusion curve showing S-shape over time. Its regional diffusion and proximity effects are significant， its vertical influence and hierarchical effects are remarkable， but its proliferation of content is mainly mimic and lacking in learning innovation. In order to promote the innovation and diffusion capacity of local governments， the central government should empower appropriately and broaden the innovation space of local governments， and the local governments should enhance their innovation consciousness and ability， exert the positive effect of vertical influence， and speed up the policy diffusion process.

Key words: local government, information transparency system, temporal and spatial evolution, policy diffusion
