The Moderating Effect of Supplier Benevolence on the Relationship between Unilateral Governance and Supplier Performance

Sungmin Ryu(류성민),Chang Hee Park(박창희) 한국유통학회 2017 流通硏究 Vol.22 No.2

본 연구는 공급자의 호의성이 일방적 통제와 공급자 성과의 관계에 미치는 효과에 관한 이해를 높이고자 하는 목적으로 실행되었다. 기업간 관계에서 성과측정은 무척 중요한데 본 연구는 192명의 구매담당자를 대상으로 신뢰의 한 단면인 기업간 호의성이 구매자의 일방적 통제가 공급자의 성과에 미치는 영향에 대해 조절효과를 갖는 것을 확인하였다. 좀 더 구체적으로는 공급자의 호의성이 높은 경우에는 구매회사가 성과를 높이기 위해 사용하는 일방적 통제의 효과가 사라지는 것을 보여주었다. 결국 기업들은 항상 일방적 통제 메카니즘을 사용할 필요가 없다는 것을 확인하였다. 또한 기업의 호의성이 약할 때에는 일방적 통제 메카니즘의 사용을 고려해야 한다는 것을 보여주었다. 하지만 본 연구는 기업간 호의성이 강할 때에는 어떤 통제 메카니즘을 사용해야 하는지에 대하여 답하지 않은 한계점을 내포하고 있다. The purpose of this study is to improve our understanding of the moderating effect of interfirm benevolence on the relationship between interfirm governance and interfirm performance. 192 purchasing managers from manufacturing companies participated in a survey. Through these, the moderating role of benevolence in the relationships between a buyer’s unilateral governance and supplier performance is identified. A buyer’s perception of a supplier’s benevolence is observed to weaken the effect of the buyer’s unilateral governance on supplier performance. Thus, this study demonstrates that firms do not always rely on unilateral governance when they can nurture interfirm benevolence in the relationship between exchange partners.

Microfluidic chips have been frequently utilized to perform biochemical analysis, like cell culture, cell-based drug screening, biomolecule synthesis, and etc, because they reduce the consumptions of analytes and reagents and automate multi-step analysis processes. It is often critical to monitor temperature in a microchannel for the analysis in order to control a reaction rate of biomolecules. We propose a novel method to monitor a temperature change in a microchannel flow by using polydiacetylene (PDA), a conjugated polymer, that has a unique property to transform its color from visible blue to fluorescent red by thermal stress. We inject PDA sensors of the form of a droplet into the microchannel with a microheater on the bottom. Preliminary results show that the florescence intensity of a PDA sensor droplets varies with the temperature.

Inter-Organizational Dependence Structures and Controls : The Moderating Effect of Credibility and Benevolence

Sungmin Ryu(류성민),Jaran Lee(이재란) 한국유통학회 2009 한국유통학회 학술대회 발표논문집 Vol.2009 No.8

Exchange parties as a social entity develop a close relationship with their exchange partners in which they nurture trust between them. Trust facilitates an exchange between channel members (Andaleeb 1992), and plays a vital role in inter-firm relationships (Morgan and Hunt 1994). Thus, it has emerged as a central component in the channels and business-to-business literatures (Wilson 1995). Several researchers imply trust could influence the level of interfirm control (e.g., Moorman et al 1992; Ouchi 1979). Ouchi (1979) argued that exchange parties must trust its exchange partner, or it should closely monitor the partner. Although trust is not directly mentioned, John (1984) points out that it is insufficient to rely only on interfirm control, so internalized social restraints must be cultivated to complement the control. The question that must be answered is what kind of control or what level of control over the exchange partner should be maintained when a party trusts its exchange partner. Despite the advanced knowledge control mechanisms have provided (e.g., Jap and Ganesan 2000; Bello et al 1997; Heide 1994), previous research exposed several gaps that have to be addressed. First, existing literature conducted in the area of business-to-business marketing is limited in explaining the influence of social context on a firm’s choice of inter-organizational control level. Secondly, although there are a couple of theoretical discussions on the dimensions of trust, credibility and benevolence (Doney and Cannon 1997; Ganesan 1994), the effect of these dimensions on interfirm control has been understudied. Benevolence is a party’s belief that its exchange partner has a motivation, which is beneficial to the party, while credibility is the belief that the exchange partner’s performance is efficient and reliable (Ganesan 1994). Since the trust sources of the two trust dimensions differ (e.g., benevolence is motivation, and credibility is performance), the effect of those on diverse interfirm controls might be different. To address these research gaps, this study proposes the condition under which a manufacturer in an asymmetrical dependence structure chooses an appropriate level of control over its supplier. We propose that the inclusion of benevolence and credibility, two dimensions of trust, may explain different levels of process and output controls in the relationship between a manufacturer and its supplier. We hope to contribute to existing knowledge on interfirm control in two ways. First, divide trust into two dimensions, benevolence and credibility, and propose the moderating effect of these dimensions on the level of interfirm control in diverse interfirm power asymmetries. Benevolence is a cognitive evaluation that is difficult to measure objectively, whereas credibility is an objective behavioral variable that is affected by output performance. Benevolence therefore might be relevant for affecting process control that is used in immeasurable performance, and credibility could be appropriate for affecting output control. Second, we divide control into two categories, process and output controls, and propose the moderating effect of credibility and benevolence on these control mechanisms. We propose that, under an asymmetrical interfirm power relationship, the level of interfirm benevolence will influence the level of interfirm process control whereas interfirm credibility would impact the manufacturer’s output control. The theoretical framework is presented in Figure 1. 〈그림 삽입〉

Impact of Channel Integration Quality on Customer Engagement in Omni-channel Retailing: The Moderating Effect of Consumer Empowerment

양옌,류성민,Yang, Yan,Ryu, Sungmin Korea Society of IT Services 2022 한국IT서비스학회지 Vol.21 No.5

Consumers are now no longer satisfied with using a single channel to shop and then desire a smooth and consistent purchasing experience across channels. By integrating different channels and services, an omni-channel strategy allows consumers to choose their preferred channel to complete their shopping tasks. Therefore, large retailers in China have recently been transforming into omni-channel retail formats to secure their competitive advantage. To better implement this strategy and optimize its effectiveness, it is important to understand how consumers respond to the quality of channel integration. Based on social exchange theory (SET), the main purposes of this study are to explore the impact of channel integration quality on consumer engagement in the Chinese omni-channel retailing environment and to further examine whether there is a moderating effect of consumer empowerment on this relationship. To test this research model, we collected data from 330 respondents by conducting an online questionnaire in China. The results indicated that the two dimensions of channel integration (breadth of channel-service choice and transparency of channel-service configuration) positively affected two dimensions of customer engagement (conscious attention and enthusiastic participation), respectively. The findings also show that consumer empowerment only positively moderates the relationship between breadth of channel service choice and conscious attention, whereas it negatively moderates the relationship between transparency of channel-service configuration and conscious attention/enthusiastic participation. Given these results, this study deepens our understanding of the impact of the quality of channel integration on customer engagement in the context of omni-channel retailing in China and sheds light on how retailers can attract consumers with different levels of empowerment.

의료 브랜드 커뮤니티의 이용욕구 충족과 커뮤니티 몰입의 관계 - 의류 브랜드 이미지의 조절효과

Hong Heesook(홍희숙),Sungmin Ryu(류성민),Chulwoll Moon(문철우) 한국마케팅과학회 2007 마케팅과학연구 Vol.17 No.4

  본 연구는 의류 브랜드 온라인 커뮤니티의 이용욕구충족과 커뮤니티 몰입간의 관계 및 이들 관계에 대한 브랜드 이미지의 조절효과를 검증하는 것이다. 9개 캐주얼 의류 브랜드 커뮤니티 회원 317명을 대상으로 온라인 서베이를 실시하여 자료를 수집하였다. 다중회귀분석 결과, 의류 브랜드 커뮤니티에서의 이용욕구 충족은 커뮤니티에 대한 몰입과 유의한 관계가 있었다. 그리고 조절회귀분석 결과, 의류 브랜드 커뮤니티에서의 관계욕구 충족이 커뮤니티 몰입(감정적 몰입, 지속적 몰입, 규범적 몰입)에 영향을 미칠때 의류 브랜드 이미지 수준에 따른 조절효과가 작용함이 발견되었다. 또한 의류 브랜드 이미지의 조절효과는 의류 브랜드 커뮤니티에서의 거래욕구 충족과 커뮤니티에 대한 감정적 몰입의 관계에서도 나타났다. 특히 의류 브랜드 커뮤니티인 경우, 커뮤니티에서의 관계욕구 충족수준에 따른 커뮤니티 몰입의 정도는 브랜드 이미지가 낮을 때 보다 높을 때 더 크게 나타났다. 이것은 의류 브랜드 커뮤니티에서의 이용욕구 충족을 통해 회원들의 커뮤니티 몰입을 증대시키는 전략은 의류 브랜드 이미지 수준이 다른 의류 브랜드 유형에 따라 그 효과에 차이가 있음을 의미한다. 따라서 의류기업의 마케터들은 자사 브랜드의 이미지 수준을 평가하고, 이에 맞춰 커뮤니티 몰입을 증대시키는 전략을 모색할 필요가 있다. 브랜드 커뮤니티에 대한 몰입은 브랜드에 대한 구전이나 재구매 행동과 연결되므로, 명품 의류 브랜드들인 경우 온라인 브랜드 커뮤니티를 구축하고 회원들의 커뮤니티에 대한 몰입을 증대시킴으로써 브랜드 자산을 극대화시킬 수 있을 것이다.   INTRODUCTION<BR>  Due to the high broadband internet penetration rate and its group-oriented culture, various types of online communities operate in Korea. This study use "Uses and Gratification Approach, and argue that members" usage-needs satisfaction with brand community is an important factor for promoting community commitment. Based on previous studies identifying the effect of brand image on consumers" responses to various marketing stimuli, this study hypothesizes that brand image can be a moderate variable affecting the relationship between usage-needs satisfaction with brand community and members" commitment to brand community. This study analyzes the influence of usage-needs satisfaction on brand community commitment and how apparel brand image affects the relationships between usage-needs satisfactions and community commitments. The hypotheses of this study are proposed as follows.<BR>  H1-3: The usage-needs satisfaction of apparel brand community (interest, transaction, relationship needs) influences emotional (H1), continuous (H2), and normative (H3) commitments to apparel brand communities.<BR>  H4-6: Apparel brand image has a moderating effect on the relationship between usage-needs satisfaction and emotional (H4), continuous (H5), and normative (H6) commitments to apparel brand communities.<BR>  METHODS<BR>  Brand communities founded by non-company affiliates were excluded and emphasis was placed instead on communities created by apparel brand companies. Among casual apparel brands registered in 6 Korean portal sites in August 2003, a total of 9 casual apparel brand online communities were chosen, depending on the level of community activity and apparel brand image. Data from 317 community members were analyzed by exploratory factor analysis, moderated regression analysis, ANOVA, and scheffe test. Among 317 respondents answered an online html-type questionnaire, 80.5% were between 16 to 25 years old. There were a total of 150 respondents from apparel brand communities(n=3) recording higher-than-average brand image scores (Mean>3.75) and a total of 162 respondents from apparel brand communities(n=6) recording lower-than-average brand image scores(Mean < 3.75). In this study, brand community commitment was measured by a 5-point Likert scale: emotional, continuous and normative commitment. The degree of usage-needs satisfaction (interest, transaction, relationship needs) was measured on a 5-point Likert scale. The level of brand image was measured by a 5-point Likert scale: strength, favorability, and uniqueness of brand associations.<BR>  RESULTS<BR>  In the results of exploratory factor analysis, the three usage-needs satisfactions with brand community were classified as interest, transaction, and relationship needs. Brand community commitment was also divided into the multi-dimensional factors: emotional, continuous, and normative commitments. The regression analysis (using a stepwise method) was used to test the influence of 3 independent variables (interest-needs satisfaction, transaction-needs, and relationship-needs satisfactions) on the 3 dependent variables (emotional, continuous and normative commitments). The three types of usage-needs satisfactions are positively associated with the three types of commitments to apparel brand communities. Therefore, hypothesis 1, 2, and 3 were significantly supported.<BR>  Moderating effects of apparel brand image on the relationship between usage-needs satisfaction and brand community commitments were tested by moderated regression analysis. The statistics result showed that the influence of transaction-needs on emotional commitment was significantly moderated by apparel brand image. In addition, apparel brand image had moderating effects on the relationship between relationship-needs satisfaction and emotional, continuous and normative commitmen

홍희숙(Hong, Heesook),류성민(Ryu, Sungmin) 한국유통학회 2012 流通硏究 Vol.17 No.3

본 연구에서는 인터넷 점포에서 의류상품 구매후기를 작성하는 동기의 유형을 규명하는 한편 작성 동기 유형에 따라 인터넷 점포 고객들을 범주화하고, 각 집단의 작성행동, 인터넷 구매 행동, 인구사회적 특성의 차이를 규명하였다. 초점집단 면접과 온라인 서베이를 통해 연구되었으며, 정량적 연구에서는 의류상품 구매후기를 읽은 경험과 작성한 경험이 많은 국내 인터넷 점포 여성 고객 252명을 대상으로 자료가 수집되었다. 연구결과, 인터넷 점포에서 구매후기를 작성하는 동기 유형은 이타적 정보 공유, 불만해소 및 보복, 경제적 보상 추구, 상품 개발 지원, 감동 표현으로 나타났다. 특히, 작성행동에 대한 영향력이 큰 동기는 이타적 정보 공유 동기와 경제적 보상 추구 동기였다. 인터넷 점포 고객은 작성 동기 유형에 따라 소비자 옹호 집단, 이익 추구 집단, 중도적 집단으로 범주화되었으며, 세 집단은 구매후기 작성행동, 인터넷 구매빈도, 인구사회적 요인들에서 차별적 특성을 보였다. 소비자 옹호 집단과 이익 추구 집단을 대상으로 인터넷 점포 구전 채널 관리 방안이 제시되었다. This study identified motives for writing apparel product reviews in online stores, and determined what motives increase the behavior of writing reviews. It also classified store customers based on the type of writing motives, and clarified the characteristics of internet purchase behavior and of a demographic profile. Data were collected from 252 females aged 20s" and 30s" who have experience of reading and writing reviews on online shopping. The five types of writing motives were altruistic information sharing, remedying of a grievance and vengeance, economic incentives, helping new product development, and the expression of satisfaction feelings. Among five motives, altruistic information sharing, economic incentives, and helping new product development stimulate writing reviews. Store customers who write reviews were classified into three groups based on their writing motive types: Other consumer advocates(29.8%), self-interested shoppers(40.5%) and shoppers with moderate motives(29.8%). There were significant differences among three groups in writing behavior (the frequency of writing reviews, writing intent of reviews, duration of writing reviews, and frequency of online shopping) and age. Based on results, managerial implications were suggested.
