기업혁신 수단으로서 사원제안제도의 영향요인에 관한 연구 : 제조업과 비제조업 비교

백상용(Baek Sang-Yong) 한국기술혁신학회 2006 기술혁신학회지 Vol.9 No.3

본 연구는 사원 개인을 분석단위로 사원제안제도의 활용에 영향을 미치는 요인을 살펴보았다. 또한 사원제안제도가 지금까지 제조업 중심으로 이루어져 왔지만 최근 서비스업을 중심으로 비제조업에도 사원제안제도가 확산됨에 따라 업종별 차이도 분석하였다. 연구 가설은 Unsworth(2001)의 개인 창의성 분류와 Frese et al.(1999)의 사원제안제도 일반 모형에서 도출하였다. 자동차 조립업체와 은행을 대상으로 자료를 수집하였고 PLS로 통계분석을 실시하였다. 연구결과를 보면 Frese et al.(1999)의 일반모형은 대체로 지지되었으며 업종 간 유의한 차이를 발견하지는 못하였다. 그러나 모형 내부 변수들의 상관관계의 정도는 유의한 통계적 차이를 보였다. 이를 바탕으로 비제조업의 사원제안제도 활용에 대한 제언을 제시하였다. This study aims to test factors on the success of Employee Suggestion Systems (ESS). Considering the difference between manufacturing and non-manufacturing firms in the use of ESS, this study analyzes the impact of the industrial sector. Partial Least Square (PLS) is employed to analyze data from employees in an automobile company and a bank. The result shows that there is no distinctive difference between two industries but there are some differences in the strength of the relationships such as the impact of pro-activity on idea generation, the work improvement on idea generation and idea generation on idea submission. Some suggestions for managing ESS in non-manufacturing firms are presented.

한국 TAM 실증연구의 동일방법편의 분석

백상용 ( Sang Yong Baek ) 한국정보시스템학회 2012 情報시스템硏究 Vol.21 No.1

Common Method Bias(CMB) may cause the potential inflation of correlations between measures assessed via the same method. The problem of CMB has been well known in behavioral sciences because the survey method with self-reporting is vulnerable to CMB. Thus, the discussion on CMB is still ongoing in the MIS research in US. However, in Korea, the MIS research has never paid attention on the CMB problem. The purpose of this study is to examine the CMB problem in the Korean MIS research. To evaluate the effect of CMB, empirical studies on Technology Acceptance Model(TAM) is selected because (1) TAM is one of the MIS research areas studied intensively, (2) TAM is a theoretical model well supported by the existing empirical studies so that the result of this study would have a great ripple effect when the CMB problem turned out to be serious, (3) CMB is domain-specific. 47 TAM samples (out of 45 studies) from three Korean Journals were selected and the relevant data were collected such as correlation matrixes and the measures of the dependent variable. To find and evaluate the size of CMB, two analytic methods (Marker-Variable Technique and Method-Method Pair Technique) are employed. The result showed that there exists CMB in the Korean studies but the problem is not so serious to distort the empirical testing, compared with that of US studies. However, considering that CMB can contaminate the testing results, Korean MIS researchers should explicitly deal with the problem in designing empirical studies and collecting data.

조절변수 탐색을 위한 기술수용모형 메타분석

백상용(Sang Yong Baek) 한국경영학회 2009 經營學硏究 Vol.38 No.5

Davis` Technology Acceptance Model(TAM) has been well received in MIS research since its inception. The popularity of TAM is based on the virtues such as parsimony, concrete theoretical supports and easy adaptability to various adoption contexts. Recently, however, there was criticism on the overuse of the model by modification and extension. This study is to investigate the limitations and future directions of TAM by performing a series of quantitative meta-analyses on the TAM studies in both Korea and US. Before performing the meta-analyses, the extant six studies of TAM meta-analysis are compared and reviewed critically. Especially, we discussed the problems of those six studies in dealing with the moderator exploration of TAM. The data for the meta-analyses are collected from 84 studies in 39 Korean articles and 40 US articles. Since the results show that all the relationships in TAM are statistically significant in both countries, we may say TAM is generally supported regardless of country. Some differences, however, are found that all of the correlation coefficients and standard deviations are greater in the Korean studies than the US ones, and that the Korean studies paid less attention on the relationship between intention and behavior than the US ones. Even importantly, all the correlation coefficients fail to pass the Q test, meaning that they are heterogeneous so that we need to explore moderators of the relationships. Before performing the analysis for exploring moderators, the classification schemes for culture, technology, and users are proposed and explained. For culture, national culture is selected because of its popularity in social sciences and distinct differences between Korea and US. For technology, four types of IT are proposed with two criteria, enjoyment and risk. For users, we examined both whether the samples are students or not and whether the samples are proxy or not. The moderator analysis shows that national culture, risk as a technology characteristic, and student as a sample characteristic are statistically significant. Especially, we find that there is an interaction effect between national culture and enjoyment, which confirms that both national culture and technology characteristics are multi-dimensional. Based on the results of all the analyses, some suggestions are presented. First, when using TAM in countries other than US, national culture should be considered in setting research models and interpreting results. Second, when applying TAM to newly developed technologies, technology characteristics should be reflected in constructing research models. Third, we should pay attention to the possible bias from student samples. Finally, the future TAM study should be devoted to the theoretical development of the IS field rather than simply enlarging the TAM application domain.

경영학 교육에 있어 강의 보조수단으로서의 웹(Web) 활용

백상용(Baek Sang-Yong) 한국경영교육학회 2004 경영교육연구 Vol.33 No.-

대학환경 변화에 따라 대학교육의 질에 대한 관심이 커지고 있다. 본 논문은 대학 강의 유형의 프레임웍을 제시하고 이를 바탕으로 학생 위주의 강의유형을 정의하였다. 그리고 이를 경영학 교육에 실행함에 있어 웹기술을 활용하는 방안에 대하여 살펴보았다. 이를 위해 현재 172개 4년제 대학의 315개 경영학 강의 웹사이트를 조사하였으며 이를 바탕으로 현재 활용 수준을 평가하고 학생 위주의 강의 유형을 위한 웹기술을 활용에 대한 방안을 제시하였다. This study deals with the current use of WWW(World Wide Web) as a complementary tool for the lectures in the Management Education in the Korean universities. To examine the status of the current lectures, a framework for categorizing the lecture types is developed and define the direction of the Korean Management education. And learning types and learning strategies are presented from the education literature. For the conceptual foundation of using WWW, a mapping of how to use WWW to install the learning strategies are performed. Then, based on the results of examining the current lecture web-sites used by Korean Management professors in 172 universities, several recommendations of how to use the web-sites as a complementary tool more effectively are suggested.

정보기술 혁신 확산과 편승 효과 : 혁신 모호성과 평가의 표준편차 Innovation Ambiguity and Assessment Standard Deviation

박경수,백상용 한국중소기업학회 2001 中小企業硏究 Vol.23 No.1

정보기술 혁신 확산에 대한 연구는 기존의 혁신 확산이론과 친혁신적 전제를 바탕으로 이루어져왔다. 이와 같은 연구 관점은 부분 확산과 혁신의 거부를 설명하는데 한계가 있으며 현실적으로 도입과 사용의 차이 또는 혁신 실패 등을 설명하지 못하였다. 본 연구는 편승효과(bandwagon effect) 관점에서 정보기술 혁신 확산을 조망하고 그에 대한 이론적 근거와 함께 수학적 모델링을 통하여 편승효과에 영향을 미치는 혁신 평가 분포의 표준편차와 모호성의 역할에 대하여 알아보고 그 의미를 분석한다. Faced with the limitation of existing theories and idiosyncratic characteristics of IT innovation, this study presents a new perspective on IT innovation adoption and diffusion of which the dominant theoretical base has been the diffusion of innovation theory. The new perspective is based on the bandwagon theory which explains the adoption of diffusion of innovation as a process of limitation within a group of relevant organizations. Using a mathematical modeling, the research shows the relationship between the standard deviation of inital assessment on an innovation and a bandwagon pressure and analyzes the interactive influence of ambiguity and the standard deviation of initial assessment on the diffusion rate. Several implications of this study are suggedted.
