Circular economy and public policies: A dynamic analysis for European SMEs
利用2015、2017和2021年三次欧洲晴雨表调查数据，分析知识溢出和环境溢出对欧洲中小企业采用循环经济实践的影响，发现两种溢出均有正向作用且环境溢出效应随时间增强。
Abstract Previous empirical studies have highlighted the importance of the institutional framework in fostering a transition towards the circular economy (CE). Adopting a dynamic approach, which merges three Flash Eurobarometer surveys conducted in 2015, 2017 and 2021 into a single dataset, we observe the evolution in the factors determining the adoption of CE practices. Firstly, using factor analysis, our results indicate two groups of institutional drivers: knowledge and environmental spillovers. Secondly, applying a multivariate probit model, we observe that both spillovers have a positive effect on the adoption of the CE. Finally, we find that the effect of knowledge spillovers remains relatively constant, while that of environmental spillovers tends to increase. This suggests that firms are increasingly benefiting from the adoption of circular practices by their peers. Policymakers should take into account that a more intense knowledge spillovers and a stronger institutional framework will increase the likelihood of European small‐ and medium‐sized enterprises (SMEs) adopting CE practices.
