혁신기반 분류체계에 따른 서비스 산업별 제품혁신 및 공정혁신의 효율성 분석

While the volume of studies on technological innovation has been increasing, most of them mainly targeted manufacturing industry and relatively neglected service industry, which only presented mixed results regarding the impact of technological innovation on firm performance. Therefore, this study classified service industry according to an innovation-based taxonomy, analyzed technological innovation efficiency, and found ways to improve it. Service industry was classified into supplier dominated, physical networks, information networks, and knowledge intensive business services while technological innovation efficiency was divided into product innovation efficiency and process innovation efficiency, which was then analyzed by service industry. Data Envelopment Analysis (DEA) was conducted on 295 service firms, excluding data with missing values for major variables, from the 'Korean Innovation Survey (KIS)' data of Science and Technology Policy Institute (STEPI). As a result, first, product innovation efficiency was high in descending order of supplier dominated, physical networks, knowledge intensive business, and information networks services. Second, process innovation efficiency was high in descending order of physical networks, supplier dominated, information networks, and knowledge intensive business services. Therefore, this study clearly analyzed the efficiency of product innovation and process innovation by service industry, which thus far had been somewhat unclear. In addition, by examining technological innovation efficiency, this study contributed to understanding of the relationship between technological innovation and firm performance.
