Policies have long been considered the essential driving force in promoting construction and demolition waste (CDW) recycling. However, the policy instruments adopted in different economies have varied greatly, which contributes to the difficulty in quantitative discernment of their effect. This study aims to examine whether the holistic employment of policy measures determines the development of CDW recycling around China. To accurately measure the holistic adoption of CDW policies, this study assessed policy strength via a proposed three-dimensional evaluation model. The spatiotemporal differences in policy strength among the 52 sample cities were further defined using K-means clustering and the Gini coefficient. Next, the driving effect of policy on the initial establishment of CDW recycling industry practices was examined by event history analysis (EHA). Finally, fuzzy set qualitative comparative analysis (fsQCA) was used to analyze the sufficiency and necessity of policy for the initial establishment of CDW recycling practices. The results indicated that the establishment of a first CDW recycling plant is only slightly correlated with policy measures, whereas it is highly correlated with the pilot city and per capita GDP. Furthermore, application of policy is neither a necessary nor sufficient condition for the establishment of a CDW recycling industry facility.
政策一直被认为是促进建筑和拆除废物（CDW）回收的重要驱动力。然而，不同经济体所采用的政策工具差异很大，这使得定量辨别其效果变得困难。本研究旨在检验整体政策措施的采用是否决定了中国各地 CDW 回收的发展。为了准确衡量 CDW 政策的整体采用情况，本研究通过提出的三维评估模型来评估政策力度。利用 K 均值聚类和基尼系数进一步定义了 52 个样本城市政策力度的时空差异。然后，通过事件历史分析（EHA）检验政策对 CDW 回收产业实践初步建立的驱动作用。最后，采用模糊集定性比较分析（fsQCA）分析政策对 CDW 回收实践初步建立的充分性和必要性。结果表明，建立第一个 CDW 回收厂与政策措施仅略有相关，而与试点城市和人均 GDP 高度相关。此外，政策的应用既不是建立 CDW 回收产业设施的必要条件，也不是充分条件。
