“…Wang et al (2021) propose that internal expenditures in R&D can create a competitive advantage for a firm (Cassiman & Veugelers, 2006), but innovative firms also require technology or knowledge from external sources when developing their innovations. Thus, performance depends on the alignment of the company's internal experience and external sources of innovation (Nguyen, Dang, et al, 2021) as a guarantee of success (Hansen, 2001), based on its learning processes and the development of its organizational competencies (Thomä & Zimmermann, 2020). This alignment or equilibrium is based on the combination, integration and acquisition of knowledge from internal and external sources, which can guarantee the generation of R&D (Hervás‐Oliver et al, 2021; Medda, 2020; Thomä & Zimmermann, 2020) since overexposure to any of them can lead to worse results than those that could be obtained with an optimal combination (Ceptureanu et al, 2021; Grimpe & Kaiser, 2010).…”
