In the era of the knowledge economy and artificial intelligence, knowledge has emerged as the most potent driving force for innovation and development, both within enterprises and at the national level. Recognizing the significance of external knowledge sources, enterprises rely on them as critical channels for acquiring knowledge. Start-up enterprises, characterized by limited establishment time, small scale, and inadequate knowledge accumulation, face an urgent need to obtain external knowledge in technology, management and marketing necessary for their production and operations. However, the phenomenon of knowledge transfer stickiness hinders the transfer of knowledge, and poses significant challenges to the innovation and development of start-up enterprises, including the incubated enterprises. Although extensive research on knowledge transfer stickiness and its influencing factors in cases involving multinational corporations and parent-subsidiary companies has been conducted, limited attention has been given to start-ups. Additionally, a comprehensive and systematic theoretical framework unraveling the mechanism of knowledge transfer stickiness is yet to be established. Thus, this study focuses on the incubated enterprises as a representative case and investigates the mechanism of knowledge transfer stickiness by utilizing in-depth interviews and qualitative research methods.#br#The study selects 16 incubated enterprises from eight business incubators located in Nanjing, Suzhou, Changzhou, and Shanghai, covering seven knowledge-intensive industries such as electronic information, software, biomedicine, nanotechnology, new energy, advanced materials, and environmental sciences, for they represent the diverse spectrum of knowledge-intensive sectors prevalent in the current business landscape. In-depth interviews are conducted with key personnel and stakeholders from the selected incubated enterprises to explore the factors contributing to knowledge transfer stickiness during the process of knowledge transfer. A total of 16 first-hand interview materials provide rich insights into the complexities and nuances of knowledge transfer stickiness within the incubated enterprises.#br#Utilizing the established coding methodology outlined by Struss and Corbin in grounded theory analysis, the study analyzes the interview materials systematically in three distinct coding stages: open coding, axial coding and selective coding. Through this rigorous process, key themes and categories related to knowledge transfer stickiness have emerged, promoting a comprehensive understanding of the underlying process mechanisms. To ensure the validity and saturation of the collected data, a subset of two interview materials is used for saturation testing, further reinforcing the credibility and reliability of the research findings. An integrated stickiness interaction approach (ISIA) model for the mechanism of knowledge transfer stickiness is constructed based upon these findings. The ISIA model provides a comprehensive framework that encapsulates the intricacies and interdependencies of knowledge transfer stickiness. It comprises four main categories: knowledge initiating stickiness, knowledge sending stickiness, knowledge interaction stickiness, and knowledge absorption stickiness. These categories are further supported by 18 subcategories, offering detailed insights into the specific dimensions of knowledge transfer stickiness and their interplay. The ISIA model highlights the temporal progression and developmental nature of knowledge transfer stickiness, emphasizing the importance of recognizing its dynamic and evolving characteristics.#br#Furthermore, the research findings indicate that the dimensions of knowledge transfer stickiness are not isolated entities but rather interconnected and mutually influencing. At each stage of the knowledge transfer process, knowledge transfer stickiness impacts subsequent stages, creating a continuous spiral-like evolution. This dynamic nature underscores the need for a holistic perspective when addressing knowledge transfer stickiness within the incubated enterprises. While knowledge transfer participants, including knowledge senders and receivers, play a pivotal role in the process of knowledge transfer stickiness. The control and governance of knowledge transfer stickiness require the active engagement and participation of these participants. The study highlights the importance of motivating knowledge transfer participants and enhancing their capabilities and willingness to facilitate successful knowledge transfer within incubated enterprises. Effective strategies for incentivizing knowledge participants, such as providing appropriate recognition, rewards, and opportunities for knowledge sharing, can foster a positive knowledge transfer culture and mitigate the challenges posed by knowledge transfer stickiness.#br#Through in-depth interviews with incubated enterprises and utilizing grounded theory as a qualitative research approach, this study contributes to the existing body of knowledge by shedding light on the process mechanisms of knowledge transfer stickiness; it also enhances the understanding of knowledge transfer stickiness in the context of incubated enterprises and provides a basis for future research.#br#
