制度变迁有需求主导型和供给主导型两种模式,分别表现为 自下而上或自上而下的向度,其间非政府主体和政府主体扮演着不同的角色。 从信息公开制度的变迁看,西方主要国家呈现为前一种模式,在我国后一种模式 的成分更多。从制度供给和制度需求的关系分析,如果供需不平衡、差异过大, 可能会影响到制度的变革。 Institutional changes are demand-led and supply-led models, which show the bottom-up or top-down perspective respectively. In the meantime, non-government actors and government actors play different roles. From the perspective of changes in the system of information disclosure, the major western countries are presented as the former model and the latter model has more components in our country. From the relationship between institutional supply and institutional demand analysis, if the imbalance between supply and demand, the difference is too large, may affect the institutional change.
