Monitoring of European‐level circular economy (CE) efficiency requires more research than does currently exists in the body of literature on CE. In this regard, this research aims to answer two research questions. Firstly, to be efficient in the implementation of CE at a macroeconomic level, should there be a relationship between the efficiency of the three phases of CE (efficiency in recycling, efficiency in the implementation of CE and efficiency of eco‐innovation)? To answer this question, we use decoupling theory. Secondly, are the three phases of CE related from the point of view of dynamic efficiency? To answer this question, we use dynamic efficiency theory.In accordance with both of these theories, we establish a circular relationship between recycling, CE and eco‐innovation. We test this circular relationship through the application of the dynamic network data envelopment analysis (DNDEA) model of Tone and Tsutsui. The analysis is based on Eurostat data for the period of 2016 to 2022 for 27 European countries.This work contributes to the advancement of the research via (1) the development of a model for measuring the transversal and longitudinal efficiency of the CE and (2) the findings of positive and significant relationships between the efficiency ratios of the three fundamental phases (recycling, CE and eco‐innovation). This leads us to affirm that the countries studied that have managed to be efficient in recycling have also been in the implementation phase of CE and eco‐innovation.

欧洲回收、循环经济和生态创新之间的关系。动态网络数据包络分析模型的应用

监测欧洲水平的循环经济 (CE) 效率需要比目前有关 CE 的文献进行更多的研究。就此而言，本研究旨在回答两个研究问题。首先，为了在宏观经济层面上有效地实施CE，CE的三个阶段的效率（回收效率、CE实施效率和生态创新效率）之间是否应该存在关系？为了回答这个问题，我们使用解耦理论。其次，从动态效率的角度来看，CE的三个阶段是否相关？为了回答这个问题，我们使用动态效率理论。根据这两个理论，我们在回收、CE和生态创新之间建立了循环关系。我们通过应用 Tone 和 Tsutsui 的动态网络数据包络分析（DNDEA）模型来测试这种循环关系。该分析基于 2016 年至 2022 年 27 个欧洲国家的欧盟统计局数据。这项工作通过 (1) 开发测量 CE 横向和纵​​向效率的模型以及 (2 ）三个基本阶段（回收、CE 和生态创新）的效率比之间存在积极且显着的关系。这使我们确信，所研究的那些能够有效回收的国家也处于CE和生态创新的实施阶段。
