Abstract

Breakthrough inventions are key factors for a firm to enhance its core competitiveness in the market. Therefore, it is imperative to promote breakthrough inventions through the transformation of scientific and technological achievements. Dual innovation stars refer to individuals who are both star scientists and star inventors, and they are crucial to the transformation of scientific and technological achievements. Existing studies generally believe that star scientists and inventors can bring more breakthrough inventions. These studies contribute to the influence of star scientists or star inventors on breakthrough inventions from a single perspective, leaving a void in dual innovation stars.
Thus, it is necessary to further examine the intrinsic mechanisms and boundary conditions of the relationships between dual innovation stars and breakthrough inventions. This paper constructs a moderated mediation model to investigate the relationships between dual innovation stars and breakthrough inventions. Scientific and technological knowledge owned by inventors is tacit, and can only be effectively transferred through face-to-face collaborations. Collaborative networks, namely scientific and technological collaboration networks, are thus being formed as a result of knowledge sharing. The overlap of scientific and technological collaboration networks may affect their transformation of scientific knowledge into technological application. This study uses network overlap as a mediator between dual innovation stars and breakthrough inventions and constructs a mediating model for dual innovation stars to generate breakthrough inventions. In addition, following the heterogeneity theory, the study reveals the boundary conditions of dual innovation stars to generate breakthrough inventions with resource heterogeneity and innovation capacity heterogeneity as contingency factors.
The study takes the inventors at Huawei and Intel as a sample, with the number of inventors being 2 603 and 4 396, respectively. It collects the scientific papers and patent data published by Huawei and Intel from the Web of Science database and the United States Patent and Trademark Office (USPTO) between 2000 and 2022, respectively. On the basis of the data fields of the authors and patent applicants, Sci2 Tool software is used to construct the internal scientific and technological cooperation networks of the two companies. The results show that dual innovation stars and?network overlap positively influence breakthrough inventions; the network overlap based on scientific and technological collaboration mediates the relationships between dual innovation stars and breakthrough inventions; resource heterogeneity positively moderates the positive relationship between the network overlap and breakthrough inventions, and further positively moderates the indirect effect of dual innovation stars on breakthrough inventions through the network overlap.
With the identification of the dual innovation stars in the companies , the study uses the network overlap to measure the similarity of scientific and technological cooperation networks, revealing the “black box” between dual innovation stars and breakthrough inventions. It not only enriches the study of scientific and technological innovation interaction, but also explains the mechanism by which dual innovation stars generate breakthrough inventions. By exploring how resource heterogeneity and innovation capability heterogeneity affect the relationship between network overlap and breakthrough inventions, the study provides management implications for firms to manage inventors′ innovation behavior. First, since dual innovation stars are important media for internal transfer and integration of technological knowledge within enterprises, managers should encourage and support dual innovation stars to host patent invention activities and achieve effective transfer of scientific knowledge to breakthrough inventions. Meanwhile, managers should actively explore potential celebrity scientists and inventors to help them transform into dual innovative celebrities. Second, inventors can establish cross-border cooperation relationships with partners, while maintaining existing technological cooperation, further expanding the cooperation relationship to the field of scientific research, promoting the exchange and integration of scientific and technological knowledge through a dual cooperation network, and thus achieving breakthrough inventions. Third, when there is high resource heterogeneity between inventors and technology partners, inventors can obtain diverse complementary resources through technology partners, and the cooperation network can play a role. Therefore, inventors should consider technological background as an important factor when choosing technology partners to avoid the trend of knowledge homogenization in the cooperation network.
