Abstract Building on the policy debate about the effectiveness of the public sector in spurring environmental innovation, the present paper investigates whether and to what extent firms pursuing different approaches to environmental innovation differently respond to policy measures (among regulatory, technology-push and demand-pull instruments). Relying on data provided by the 2012 Italian Community Innovation Survey (CIS), the empirical exercise adopts a clustering approach to identify divergent innovation trajectories (EI modes) and a logistic regression model to explore the institutional drivers of distinct EI modes. The results from 1.807 manufacturing firms indicate that the role of public policies in stimulating EI practices changes in sign and magnitude across EI policy tools and modes. This study contributes to literature by providing an enriched and more nuanced view of environmental innovation processes, with important implications for the theorization of distinct classes of policy aimed at fostering the transition towards increased sustainability.

展现异质性：不同生态创新模式的不同政策驱动力

摘要 基于关于公共部门在刺激环境创新方面的有效性的政策辩论，本文调查了采用不同环境创新方法的公司是否以及在多大程度上对政策措施（监管、技术推动和需求拉动）做出了不同的反应。仪器）。依靠 2012 年意大利社区创新调查 (CIS) 提供的数据，实证研究采用聚类方法来识别不同的创新轨迹（EI 模式）和逻辑回归模型，以探索不同 EI 模式的制度驱动因素。来自 1.807 家制造企业的结果表明，公共政策在刺激 EI 实践中的作用在 EI 政策工具和模式中的符号和幅度发生了变化。
