摘　　要：作为一项关涉社会民生与可持续发展的重要政策议题,城市生活垃圾分类政策近年来在全国范围内纷纷落地。以政策扩散为理论视角,对我国31个省级、38个地级重点城市的生活垃圾分类政策的时空演进特征及其扩散机理进行实证分析发现,我国地方城市生活垃圾分类政策扩散的时空演进体现出如下运行机理:在时间维度上地方城市生活垃圾分类政策随时间变动呈现S型扩散曲线,目前处于曲线第二阶段,即快速增长时期;在空间维度上呈现出比较显著的邻近效应,同区域内政策先行地区对周边地区具有示范带动作用;在具体路径上呈现出显著的垂直影响,包括自上而下的层级扩散和自下而上的吸纳扩散两种模式;在主要内容上呈现出效仿与创新失衡,以简单效仿为主,政策创新性不足等。城市生活垃圾分类工作历时多年,但依然任重而道远。As an important policy issue concerning people’s wellbeing and sustainable development,the classification policy of urban domestic waste has been implemented nationwide in recent years.Based on the theoretical perspective of policy diffusion,this paper makes an empirical analysis on the temporal and spatial evolution characteristics and diffusion mechanism of domestic waste classification policies in 31 provincial-level and 38 prefecture-level key cities in China.It is found that the urban temporal and spatial evolution of domestic waste classification policies in China presents the following operating mechanism:in the time dimension,the urban domestic waste classification policies show a S-shaped diffusion curve with time changes,which is currently in the second stage of the curve,that is,a period of rapid growth;in the spatial dimension,there is a significant proximity effect,and the policy-leading areas in the same region have a demonstration and driving effect on the surrounding areas;there is a significant vertical influence on the specific path,including top-down hierarchical diffusion and bottom-up absorption diffusion;in the main content,there is an imbalance between imitation and innovation,which is mainly based on simple imitation and lack of policy innovation.The classification of urban domestic waste has lasted for many years,but it still has a long way to go.
