Eco-innovation (EI) as a conceptual approach has gained significant momentum in the transition of the manufacturing sector towards sustainability. This paper aims to contribute to the study of the research landscape on EI in the manufacturing industry by applying a bibliometric methodology and identifying prevailing trends and concepts used in academic literature. For this purpose, search engines such as Scopus and Web of Science (WoS) were utilized, along with analytical tools such as Bibliometrix, Microsoft Excel, and Gephi. The search was conducted using equations constructed from keywords deemed relevant to the objective, and the records obtained from the databases were consolidated into a single repository for joint analysis using the RStudio platform. The findings revealed an increase in scientific production from 2010 onwards. The analysis identified that the most influential authors, affiliations, and documents primarily originate from Spain, Germany, and China. The key concepts identified are the circular economy, eco-design, and green technologies, which provide a holistic framework for improving efficiency, reducing waste, and mitigating environmental impacts. EI promotes close collaboration between industries to reduce the ecological footprint. Nonetheless, there is a notable gap in research about EI in the shipbuilding industry, necessitating further exploration in the sector. This study lays a foundation for future investigations in this evolving domain.

Over the last four decades, innovation capability has been studied to examine the innovation phenomenon based on the specific characteristics of organizations and systems under the theory of resources and capabilities. However, "capability" has diverse applications, and its correlation with innovation remains unclear. This study aims to clarify the definition of "innovation capability" in the context of the manufacturing industry and to comprehend how researchers presently investigate this concept. In order to meet this, an exhaustive search was conducted in the Scopus and Web of Science (WoS) databases, covering the period from 2018 to 2023. The selection of documents for analysis was determined by applying the scientometric method. The authors of this research identified 462 documents, and the bibliometric analysis, conducted using VOS viewer and Bibliometrix tools, revealed four main thematic areas within the research domain: sustainability, business performance, technology transfer, and knowledge management. As a result, this study identified the seminal authors of the concept. It provided a precise definition of "innovation capability", highlighting the significant interest that this research topic arouses in current academic literature.

The phenomenon of innovation, analyzed from the perspective of internal organizational capabilities, becomes accessible through strategic decisions and configurations established by management to enhance corporate performance. In the manufacturing sector, innovation capability (IC) is a critical factor, as it facilitates competitiveness through the development and refinement of products and business processes. This literature review aims to understand the dimensions and application of the term “Innovation Capability” (IC) by identifying the tools used for its measurement and comparison in a comprehensive analysis of studies conducted in the manufacturing industry. To achieve this, a review of academic records published between 2018 and 2023 was conducted, utilizing Scopus and Web of Science (WoS) databases, following PRISMA methodology guidelines. A total of 98 documents focused on the study of IC in manufacturing companies were identified. The reviewed documents collectively analyze IC through nine thematic axes and provide tools for its measurement. Based on the observed results in the records, a framework is proposed that synthesizes the variables related to measuring IC in organizations. This study proposes a novel framework that synthesizes the nine thematic axes for measuring IC in manufacturing, addressing the limitations of previous reviews by integrating organizational, environmental, and technological dimensions. Furthermore, it highlights opportunities for future research to explore and apply the identified instruments in other industries and contexts.
