제품혁신과 프로세스혁신의 지속성(persistence) 및 상호작용:하도급 체제의 조절 효과

This paper examined the outcome persistence of, and the reciprocal interactions between, the product and process innovation, and investigated whether the structure of innovation persistence varies depending on the embeddedness in the subcontracting regimes. Using the survey data of the Workplace Panel Survey gathered from 2015 to 2019, this study demonstrated that the current product and process innovation drives the next success of product and process innovation, and the persistence in product and process innovation is not stable over time. Further, product innovation in the current period affects the next period of process innovation with stable persistence and the successful process innovation of the current period increases the success possibility of the next product innovation. Meanwhile, persistent technological innovation and interaction between product and process innovation can be expected in workplaces independent of the subcontracting regimes. However, there is no interaction between product and process innovation in workplaces that are embedded in the subcontracting regimes. This study contributes to the literature by explaining that technological innovations of workplaces embedded in the subcontracting regimes are less persistent and that the subcontracting regimes can restrict technological innovation not only for subcontractors but also for the whole industry.
