본 연구는 ERP 시스템이 기업성과에 미치는 영향에 대하여 ERP 도입효과에 대한 분석 차원에서 이루어졌다. ERP 패키지를 도입한 국내 주요기업과 미도입 기업과의 재무적 성과를 도입시점을 전후로 나누어 비교분석하고 세부적으로는 도입기업을 대상으로 기존 연구들에서 공통적으로 언급된 ERP 도입의 핵심성공요인을 바탕으로 카테고리를 나누어 각각의 성공요인에 대한 성과 측정의 측면에서 객관적인 재무정보를 이용하여 ERP 구축에 따른 경영성과가 어떤 경우에 우월하게 발생하였는지를 탐험적으로 알아보았다. 그 결과 ERP 도입 시에 재무적으로 영향을 미치는 성공요인으로는 PI 시행 여부, Extended ERP 도입 여부, Task Force 팀 유지 여부, 변화관리 유무 등으로 나타났다. 장기적이고 지속적인 ERP 적응 노력이 이러한 주요 변수의 공통적인 성격임을 추론할 때 궁극적인 도입효과에 있어 기업의 장기적인 수행능력(capability) 향상 노력이 단기적인 IT 자원(resource)의 구축과 함께 강조되어야 함을 보여 주고 있다. This study is to investigate the impact of ERP package system on firm`s financial performance. Upon the conflicting results of previous a few studies on ERP impact on firm performance, this study tries to make the financial comparison between ERP-adopted and not-adopted firms among major Korean firms through a matched sample comparison group methodology and publicly available financial ratings. In addition, based on the key success factors for ERP adoption and implementation from previous studies, we test if these factors can make the difference in the financial performance among the ERP-adopted firms. Results indicate that firms with and without ERP do not show any statistically significant difference in financial performance over 3 years of time span before and after ERP adoption. However, among the ERP adopters, ones with successful PI implementation, Extended ERP implemantion, post-ERP Task Force Team, long term change management effort show the relatively strong financial performance than ones without these factors. This study findings overally indicate that while ERP system in major Korean firms may not produce the significant impacts on the firm`s financial performance yet, long term commitment and the development of IT capability to successfully use the ERP systems, as represented by the identified success factors above, would decide the winner of ERP venture in the long run.

이중정 ( Lee Choong C. ),안재영 ( An Jaeyoung ),김행미 ( Kim Haengmi ),김우석 ( Kim Wooseok ) 한국지식경영학회 2020 지식경영연구 Vol.21 No.4

공유경제가 디지털 서비스 플랫폼을 기반으로 한 새로운 경제체계로 인식되고 있지만, 국내에서는 사회적인 인식과 이해의 부족으로 공유경제가 아직 자리잡지 못하고 있다. 해외 경제 선진국과 같이 새로운 비즈니스를 창출하고, 이를 통해 신규 시장을 개척하기 위해 공유경제를 긍정적 관점에서 바라보고 이해할 필요성이 있다. 이에 본 연구에서는 전세계 각 학문 분야에서 진행된 지난 10년간 공유경제 연구를 수집하여 학술적 관점에서 공유경제 연구의 현황을 살펴보고, 더 나아가 이 중에서 MIS 영역의 연구를 선별하여, 공유경제 내 MIS 영역 연구의 동향도 분석해 보았다. 본 연구를 통해 공유경제와 MIS 연구의 연구 흐름을 확인하였고, 공유경제에서의 MIS 연구 중요도와 연관성을 살펴봄으로써 두 연구 간 학제적 연구의 필요성도 도출하였다. 따라서 다양한 학문적 접점을 가진 공유경제가 인접 학문의 활발한 연구를 독려하고, 더 나아가 사회, 경제, 산업적으로 보다 긍정적으로 한국에 자리매김하는데 본 연구가 기여할 수 있기를 기대한다. The sharing economy is recognized as a new economic system based on the digital service platform, but the sharing economy has yet to be established in Korea due to a lack of social awareness and understanding. There is a need to enhance understanding and awareness of the sharing economy in positive perspective in order to make up business with advanced economies global and explore new markets. In this study, after collecting papers of the sharing economy over the past decade published by each academic field around the world, we reviewed them from academic lens and conducted a comprehensive analysis using meta analysis methodology. Then, we selected papers of MIS field and analyzed the trends of the MIS field research in these papers. As a result we identified the research trend of the sharing economy and the MIS research and drew the necessity of interdisciplinary research between the two studies by examining importance and relevance of MIS research in the sharing economy research. Therefore, we expect that this study contributes to promote interdisciplinary research with neighboring disciplines and to establish a positive social, economical and industrial position in Korea.

모바일 쿠폰과 멤버십 카드를 통합적으로 관리하는 모바일 지갑은 사용 편리성과 경제적 혜택으로 인해 빠르게 성장하고 있는 모바일 서비스 중의 하나이다. 그러나 빠른 성장에도 불구하고 모바일 지갑을 지속적으로 사용하지 않는 단기 사용자의 증가는 모바일 지갑 서비스 제공자들이 수익창출을 위해 해결해야 할 주요한 문제점이 되고 있다. 본 연구에서는 모바일 지갑 사용자의 서비스 사용기간을 늘리기 위한 주요 고려사항을 도출하기 위해, 모바일 지갑사용자의 지속적인 사용의도에 영향을 주는 요인을 이익(Benefit)과 비용(Sacrifice)측면으로 나누어 종합적으로 분석 가능한 VAM(Value-based Adoption Model)을 적용하여 검증하였다. 연구결과, 이익 측면에서는 유용성, 가치표현, 인지된 보안과 즐거움이 지각된 가치에 유의한 영향을 미치는 것으로 나타났으며, 비용 측면에서는 기술의 복잡성이 지각된 가치에 유의한 영향을 미치는 것으로 확인되었다. 또한, 지각된 가치는 지속사용의도와 유의한 관계를 갖는 것으로 검증되었다. 본 연구결과를 활용해 모바일 지갑 서비스 제공자가 단기 사용자를 위한 서비스의 개선 및 마케팅 시에 기능 측면뿐만 아니라 감성적 측면의 요인들까지 고려할 수 있을 것으로 기대한다. Mobile wallet that can keep coupons and membership cards for mobile is one of rapidly growing services due to its usability and financial benefit. However, in spite of its rapid growth, the increase of users who do not use continuously it is an important consideration to service providers for making a profit. This study aims to test the effects of factors affecting the continuous use intention of mobile wallet based on VAM (Value-based Adoption Model) which can analyse them in both benefit and sacrifice aspects, so as to suggest considerations to increase the use period of mobile wallet for service providers. The research findings supported the hypotheses regarding to the effects of usefulness, value-expression, perceived security and enjoyment in the benefit aspect and technicality in the sacrifice aspect on perceived value. In addition, the causal path from perceived value to continuous use intention was significant. The study results are expected to be used in marketing or service improvement for short-term users by taking account of emotional factors as well as functional factors.

업무특성과 BSC 시스템 특성의 적합도가 BSC 시스템 사용자 만족도에 미치는 영향

The balanced scorecard(BSC) framework is a tool for strategic decision making and task support that aims for efficiency in performance management and strategy execution. BSC evolved from an old performance management practice, which tended to be limited to a finance-only perspective, to a new system of corporate management looking at corporate tasks from a multi-dimensional, future-inclined value perspective. This form of BSC amounts to a framework capable of driving management innovation and renewing the ways in which companies conceive their strategy and perform their operations. Since BSC draws integrally on user participation, it can be expected that users' satisfaction with BSC systems is an important factor in systems' success or failure. However, previous studies of the BSC system have not yet considered it as a theoretical model, specifically examining BSC system and task characteristics. To date, only a few studies have put forward plans for the implementation and use of BSC systems, and these studies have the common limitation of failing to consider the circumstances or theoretical structure of the companies for which a BSC system is being proposed. This paper then begins to fill some of this gap by characterizing the BSC system from the perspective of contingency theories. Contingency theories can be particularly useful in the Korean context in exploring how different companies use the BSC system in ways determined by their unique environmental characteristics, which may also determine the performance factors behind the application of a company's particular BSC system. In order to provide concrete suggestions for implanting and using the BSC system from a contingency theory perspective, this study sets out to determine the relationships between the contingency variables affecting BSC system performance and BSC system property variables(in given cases) through an empirical analysis. The study takes into account the perspective from which contingency theory is to be applied in individual cases, sets contingency and BSC property variables with reference to the BSC system user's environment and BSC system's character, and frames initial hypotheses concerning corporate structure and environmental variables and BSC system performance variables with reference to previous studies. A survey was then conducted on users in Korean companies that have implemented the BSC system in order to verify the research model and understand results.

Information Suppression and Projection Strategies Depending on Personality Traits: Using Social media for Impression Management

윤혜정,이한별,이중정,Yun, Haejung,Lee, Hanbyeol,Lee, Choong C. The Knowledge Management Society of Korea 2017 지식경영연구 Vol.18 No.3

As social media started to work as important communication tools, social media users have tried to manage their image, identity, and impression through social media. Social media service providers have been interested in providing various functions effectively disclosing users' emotion, such as posting, commenting, and sharing content; on the other hand, relatively few efforts have been made to provide social media functions for information suppression. In this study, therefore, we attempt to examine the relationship between Facebook users' personality and impression management behaviors. Personal traits of users including public self-consciousness, positive self-expression, and honest self-expression were considered as independent variables. Impression management behaviors are composed of two variables, which are suppression and projection. The survey was conducted, targeting 230 Facebook users. The research findings show that public self-consciousness and positive self-expression are positively associated with information suppression while both positive and honest self-expression is positively associated with information projection.

이충훈 ( Chung Hun Lee ),맹윤호 ( Yun Ho Maeng ),이중정 ( Choong C Lee ) (주)엘지씨엔에스(구 LGCNS 엔트루정보기술연구소) 2015 Entrue Journal of Information Technology Vol.14 No.2

프라이버시를 중요하게 생각하지만 그에 부합하지 않게 행동하는 것을 프라이버시 패러독스(Privacy Paradox)라고 한다. 이러한 사용자의 프라이버시 패러독스가 가장 많이 일어나는 온라인 서비스가 SNS이며, 프라이버시 침해나 범죄의 원인이 되고 있다. SNS 사용자의 자발적인 개인정보 공개로 발생한 문제는 기업의 이미지 실추와 재무적 손실까지 초래할 수 있다. 따라서 사용자의 개인정보 관리는 SNS 제공자에게 중요한 관리 요소이며, 사용자 간의 관계형성을 기반으로 하는 SNS 특성을 고려할 때, 프라이버시 패러독스는 개인정보 관리에서 중요한 고려사항이다. 본 연구에서는 동기이론을 적용하여 SNS 사용자의 프라이버시 패러독스를 유발하는 내·외적 요인들을 종합적으로 분석하였다. 연구결과, 내적 요인보다는 외적 요인이 프라이버시 패러독스를 유발하는 것으로 나타났다. 그리고 내적 요인에서는 인지된 행동통제가 부주의한 개인정보 제공에만 영향을 미쳤으며, 외적 요인에서는 주관적 규범, 기업 명성이 부주의한 개인정보 제공과 공개에 영향을 주고 보상은 부주의한 개인정보 공개에만 영향을 미치는 것으로 검증되었다. 본 연구결과는 SNS 제공자들이 사용자들의 프라이버시 관련 행동을 이해하는 데 있어서 유용한 참고자료가 될 것으로 기대한다. Privacy paradox is online users` careless behavior opposite to careful attitude in the protection of their personal information. It has often arisen on SNS and has become the source of privacy invasion or crime. The problems caused by SNS user`s volutary disclosure of personal informaton can result in the fall of company image and finacial losses. Therefore, the protection of users` personal information is critical to SNS providers, and considering SNS based on the relationship among users, privacy paradox is the important consideration in personal informaton protection. This study aims to investigate the factors affecting the SNS users` privacy paradox based on motivation theory which can analyse them in both intrinsic and extrinsic aspects. The research findings showed that the extrinsic factors were the causes of the privacy paradox. To be specific, perceived behavioral control was the only affecting factor on inconsistent provision of personal information in the intrinsic aspect, and subjective norm and corporate reputation had significant relationship with inconsistent provision and disclosure of personal information in extrinsic aspect. On the other hand, compenstion had the only effect on inconsistent disclosure of personal information. The study results are expected to provide considerations for SNS provoiders to understand users` behavior related to the privacy.

While the fierce competition in e-commerce market continues to be escalated, more and more e-commerce firms is trying to secure loyal customers through membership marketing. However, as many marketers see the importance of membeship marketing, many firms still don"t clearly understand the unique characteristics of their paid membership customers so that the firms can transform them into loyal customers. Surprisingly, there are very few researches to study the unique characteristics of paid membership customers, that is, investigating how they are different from no-membership customers in terms of the type of service, their interest/ concern, and their expectation in purchasing experience. Therefore, this study explore and compare the key issues between customers with and without paid membership in e-commerce business. The differences in the key issues were derived from text-mining technique(i.e., LDA topic modeling and word frequency analysis) with the customer review data. For the results of the LDA topic modeling, we derived topics of membership, purchased products, events, and payment methods from the customers with paid membership, and membership and purchased products from the customers without paid membership. In addition, for the result of the word frequency analysis, we derived issues of price discount from the customers with paid membership, and purchase/use experience and product information from the customers without paid membership. The result of this study has practical implication that contribute to provide the detailed marketing strategies for each customer group based on the better comparative understanding of paid membership customers over no membership customer group.

In the growth of IT industry, interest in wearable device has been globally rising along with the evolution of technology. A Smartwatch is expected to be at the center of wearable device industry in the future. However, there are some concerns that most of its actual sales are caused by gifts or bundling. Motivated by these issues, this study propounds the ideas that to enter the mainstream market, the empirical research is required for actual consumers who continue to use a smartwatch. The purpose of this study is to identify key factors affecting user satisfaction and antecedents affecting continuance intention to use from consumer perspectives. Further, assuming consumers perceptions will be different according to how they acquired smartwatch, this study classified the group as direct buyers and acquired users. To achieve the purpose of the research, this study analyzes the usage of smartwatch by integrating the IS Success Model and IS Continuance and Habit Theory. We implemented the survey of 338 smartwatch users, and the research findings indicate that information quality and system quality have significant effects on satisfaction, and consequently satisfaction and habit positively affect the continuance intention to use. Additionally, it is found that there was a significant difference in the relationship between satisfaction and habit in the group divided by acquisition type. Based on these findings, this study provides theoretical and practical implications.

본 연구는 스마트폰 확산 전략에 관한 연구로, 스마트폰의 수용 단계별 사용자 성향과 이에 따른 다양한 애플리케이션의 사용 활성화 측면에서의 차이점을 심도 있게 비교 분석하였다. 본 연구에서는 스마트폰 앱스토어 이용에 영향을 주는 요인으로 개인 특성(개혁성, 과시성향, 자기효능감, 사회적 영향정도)과 기술인식 성향(앱스토어에 대한 인지된 유용성, 용이성)을 중심으로 분석하였고, 스마트폰 수용 단계별 차이점을 분석하기 위해 수용 단계를 3단계(1단계: 조기 수용자, 2단계: 일반 수용자, 3단계: 잠재 수용자)로 나누어, 수용 단계별 개인특성, 기술인식 성향, 앱스토어 이용의향, 선호 애플리케이션 종류 등을 비교 분석하였다. 연구 결과, 사회적 영향 정도를 제외한 모든 개인 특성과 앱스토어에 대한 기술인식 성향, 앱스토어 이용 의향에 있어 3개의 수용 단계별로 유의한 차이가 나타났으며, 수용 단계별 선호 애플리케이션 카테고리 분석 결과, 공통의 선호도와 함께 특정 카테고리에 대한 선호도의 차이를 보였다. 또한 성별, 단말 OS별 집단에서 기술인식 성향과 앱스토어 이용에서의 차이점이 나타났다. The objective of this paper is to make a comparative study on smartphone app store use and user`s characteristics based on three different stages of adoption. This study focuses on users` individual characteristics(Innovativeness, Conspicuous consumption, Self-efficacy and Social influence) and perceptions toward technology(Perceived usefulness & Perceived ease of use toward Smartphone App Store) as important influencers on the use of smartphone app store. We classify smartphone users into three adoption stages(1st: Early Adopter, 2nd: Late Adopter, 3rd: Potential Adopter) for comparative analyses among adoption stage groups. The results indicate that there are differences in individual characteristics(Except social influence), perceived usefulness and perceived ease of use toward smartphone app store, intention to use smartphone app store and preference in smartphone apps` categories among adoption stage groups. Also, there are differences among gender groups and device OS`s groups.
