Abstract: “This study examines the relationship among supplier knowledge development capability, supplier integration, knowledge sharing, and product innovation. Data were collected from a questionnaire survey, and 210 responses from participants were analyzed using structural equation modeling. After the survey, interviews were conducted to obtain a clearer idea about the real-life situation. Results from the questionnaire show that supplier knowledge development capability is positively related to supplier integration and product innovation. Therefore, firms can include supplier knowledge capability as a criterion when selecting suppliers. The results also have two connected conclusions: a higher level of supplier integration can lead to a higher level of product innovation and knowledge sharing, and more frequent knowledge sharing practices can also encourage product innovation.”
