The purpose of this paper is to study empirically the relationships between innovative work be-haviour and process innovation. The paper hypothesis was created in the light of the literature. That hypothesis is validated using the Partial Least Squares, by Smart PLS statistical program, data collected by the survey method from the 62 firms located in technoparks in Istanbul. The findings revealed that innovative work behaviour is considered to be one of the key factors in both increasing and inhibiting process innovation. The findings supported our hypothesis. There is significant and positive relationships between innovative work behaviour and process inno-vation. This research presents findings that firms should support innovative work behaviour in order to increase process innovation. This paper jointly examines as an empirically in the same model the little-researched links between innovative work behaviour and process innovation.
