This paper explores the effect of digital and green servitization on firms' technological innovation performances. Drawing on the Organisational Learning Capabilities (OLC) and Dynamic Capabilities theories, we conjecture that digital and green servitization represent a crucial learning mechanism for firms that translates into an ampler set of dynamic capabilities, including the ability to produce technological innovation. To test these hypotheses, we employ a Propensity Score Matching (PSM) approach and compare the innovation intensity between firms that engage in Digital, Green or both (digital and green) servitization and those that do not provide these services. Our evidence uncovers a positive relationship between digital servitization and firms' innovative performances. On the contrary, our results reveal that firms that offer green services are less likely to be highly innovative compared to those that do not provide this type of service and suggest the existence of positive complementarities between Digital and Green services in shaping firms' innovative performances. Additionally, we find that public innovation investments foster the effect of digital and green servitization on firms' ability to be highly innovative These results have significant implications for managers' and policymakers' ability to boost firms’ innovativeness during the transition toward a circular economy.

本文探讨了数字化和绿色服务化对企业技术创新绩效的影响。借鉴组织学习能力（OLC）和动态能力理论，我们推测数字和绿色服务化代表了企业的重要学习机制，可以转化为更丰富的动态能力，包括产生技术创新的能力。为了检验这些假设，我们采用倾向得分匹配（PSM）方法，比较从事数字、绿色或两者（数字和绿色）服务化的公司与不提供这些服务的公司之间的创新强度。我们的证据揭示了数字服务化与企业创新绩效之间的正相关关系。相反，我们的结果表明，与不提供此类服务的企业相比，提供绿色服务的企业不太可能具有高度创新性，这表明数字服务和绿色服务在塑造企业创新绩效方面存在积极的互补性。此外，我们发现公共创新投资促进了数字和绿色服务化对企业高度创新能力的影响。这些结果对于管理者和政策制定者在向循环经济转型期间提高企业创新能力的能力具有重大影响。
