초록
소비자들이 지각하는 제품의 혁신성을 측정하는 척도를 개발하고 그 타당도를 검증하기 위하여 연구를 진행하였다. 연구 1에서는 소비자의 지각된 제품혁신성을 정의하고 요인과 문항을 구성하기 위하여 선행연구를 개괄하였으며, 소비자들을 대상으로 FGI(Focus Group Interview)를 진행하였다. 높은 수준과 중간 수준의 혁신성 제품을 이용하여 탐색적 요인분석을 실시하였으며, 기존연구에서 사용되던 문항들과의 상관분석을 실시하고, 두 혁신 제품들 간의 지각된 제품혁신성을 비교하였다. 연구결과, 참신성과 진일보성의 2요인 10문항이 최종적으로 추출되었으며, 유재미 등(2006)의 문항들과는 약 .7정도의 상관이 나타났으나 Moreau 등(2001)의 척도와는 약 .5정도의 상관이 나타났다. 또한 개발 척도는 높은 수준의 혁신성 제품과 중간 수준의 혁신성 제품을 잘 변별하였다. 연구 2에서는 연구 1에서 결정된 2요인 10문항 척도의 구성개념을 확인적 요인분석을 통하여 검증하였으며, 선행연구들에서 나타난 1요인 모형과 2요인 모형을 비교한 결과 2요인 모형이 더 나은 모형적합도를 보였다. 제품 구매태도와 구매의도에서 개발척도가 유재미 등(2006)의 문항들에 비해 추가적인 설명량을 가지고 있는 것으로 나타났다. 또한 소비자의 지각된 제품혁신성이 제품 구매태도와 구매의도에 미치는 영향을 분석한 결과, 지각된 제품혁신성이 제품 구매에 긍정적인 영향을 주고 있는 것으로 나타났으며, 이러한 설명량은 제품의 혁신수준에 따라서 차이가 존재하였다. 마지막으로 본 연구의 의의와 제한점 및 추후 연구를 위한 제언을 논의하였다.
Abstract
The present study develop and validate Consumers’ perceived Product Innovation Scale. In study 1, review studies and conduct Focus Group Interview to define the consumers’ perceived product innovation and develop items by defined operation definition. Conducted the exploratory factor analysis with high level innovation product and middle level product and explored a correlation with the items in advanced study and compared between the innovation level of two product. In result, extracted 2-factor structure and 10 items and revealed around .7 correlation coefficients with the items of Ryu et al.(2006) and around .5 correlation coefficients with the items of moreau etc.(2001). The developed scale distinguish between high level innovation product and middle level product. In study 2, the 2-factor structure of the scale identified on study 1 was supported by confirmatory factor analysis using a structural equation modeling. The result of confirmatory factor analysis showed that 2-factor model had a better fit to the data than the 1 factor model in the advanced studies. The developed scale has additional R-square in purchase attitude and purchase intent than the items in Ryu et al.(2006)’s research. In addition, consumers' perceived product innovation has a positive influence to an acceptance of innovation product and there’s differences between the R-square of two products. Finally, the implication, limitations, and future directions of this study are discussed.
