Efficient interface integration across different functional departments-particularly between the RInD and marketing departments-within firms has become a fundamental factor for successful new product development （NPD）. In terms of NPD, the mechanism between the R＆D-Marketing interface integration, influential factors including information prompting, organizational motivating and environmental driving factors, and the NPD performance functions as follows. Information prompting and organizational motivating factors have a significant positive impact on the R＆D-Marketing interface integration and the NPD performance of IT firms. Environmental driving factors exert a certain indirect impact on R＆D-Marketing interface integration through information prompting and organizational motivating factors, while R＆D-Marketing interface integration has a significant positive impact on the NPD performance.Therefore, IT firms pursuing better NPD performance are advised to improve their R＆D-Marketing interface by managing the relevant factors.
