“…R&D collaboration breadth, or the number of distinct external partners (i.e., competitors, universities, suppliers, customers) with which a firm collaborates simultaneously (Faems et al, 2010), is a powerful strategy that enables firms to build competitive advantages and increase value by exchanging and sharing their resources with those of other entities along the supply chain (Godlewska et al, 2022;Van Beers & Zand, 2014). The study of R&D collaboration breadth has gained considerable relevance in today's complex landscape, where family firms are increasingly looking to create interactive innovation networks with different types of partners to address issues related to shortening innovation cycles, decreasing R&D costs, enhancing firm outcomes, and ultimately creating value for all stakeholders (Ferreras-Méndez et al, 2015;Martínez-Alonso et al, 2022a;Martínez-Romero et al, 2020). Accordingly, R&D collaboration breadth is crucial for firms' long-term survival (Lyu et al, 2020;Stuart, 2000), and specifically, it is essential for family firms to survive across generations (Bigliardi & Galati, 2018;Feranita et al, 2017).…”
