기업간 상생(공급 사슬 관리)이 강조되면서 기업의 구매관행이 변하고 있다. 구매기업들은 소수의 협력업체와 장기적 거래관계를 유지하며 협력업체와 파트너십을 통한 기업경쟁력 제고에 힘쓰고 있다. 이에 협력업체들의 당면과제는 구매기업의 소수협력업체로 선정되고 안정적 거래물량확보 및 사업기회를 얻기 위하여 어떻게 효과적으로 구매기업의 구매전략에 대응할 것인가일 것이다. 본 연구에서는 구매기업이 아닌 협력업체의 관점에서 협력업체의 어떤 요인이 구매기업과의 파트너십 형성에 영향을 주는지, 그리고 강화된 파트너십이구매기업의 주문량배분 결정에 유의한 영향을 미치는지 알아보고자 한다. 협력업체의 성과(품질, 인도 성과, 기술경쟁력, 대응성, 원가절감), 구매기업과의 파트너십(신뢰 및 협력)의 강도, 그리고 구매기업의 협력업체에 대한 주문량배분 결정을 변수로 사용하였다. 미국의 기업들을 대상으로 설문조사한 자료를 바탕으로 회귀분석을 사용하여 분석하였다. 분석 결과 협력업체의 대응성, 원가절감능력 및 기술경쟁력이 구매기업의 협력업체에 대한 신뢰와 협력 증진에 긍정적인 영향을 주는 것으로 나타났다. 그러나 예상과 달리 공급업체에 대한 구매기업의 신뢰 및 협력 수준의 증가는 구매기업의 협력업체에 대한 주문량 증가로 직접 연결되지는 않는 것으로 나타났다. Under supply chain management, manufacturing firms’ procurement practices have undergone considerable changes. Manufacturing firms increasingly tend to reduce the number of suppliers and maintain close ties with the key suppliers. In order to sustain profitable growth under the circumstances, suppliers should focus on how they gain greater shares of the current customers(buyers)’ business. In this context, we investigate the relationship among suppplier’s performance, SCMattributes(trust and collaboration) and buyer’s order allocation. Our research questions are 1) what type of supplier performance attributes (quality, delivery, cost, responsiveness, and technological capability) significantly affect the buying firm’s trust on and collaboration with the supplier and in turn 2) whether or not a higher level of buying firm’s trust and collaboration can lead to a larger amount of order allocation as a reward for the supplier.We analyze the data collected fromNorth American firms, usingmultiple regression analysis. The analytical results provide evidence that a supplier’s superior performance in responsiveness, cost, and technological capability has a positive influence on the buying firm’s level of trust on and collaboration with the supplier. However, a higher level of buying firm’s trust on and collaboration with the supplier may not translate into a larger order allocation to the supplier.

2019년 코로나 바이러스(COVID-19)의 대유행 기간 동안 비대면 소매가 안전한 쇼핑을 위한 대안으로 떠올랐다. 2차 자료 바탕의 연구에서 온라인 및 모바일 쇼핑의 매출이 크게 증가한 것으로 보고되었으나, 온라인 쇼핑에 대한 소비자의 행동의도에 체계적으로 영향을 미치는 심리적, 인지적 요인에 초점을 맞춘 연구는 부족한 현실이다. 이 연구는 특히 COVID-19에 대한 인지된 심각도와 취약성이 온라인 또는 모바일 쇼핑을 사용하려는 소비자의 의도에 미치는 영향을 파악하였으며 소비자의 자가격리 성향(Self-isolation)을 매개자로, 주관적 규범(Subjected norm)을 쇼핑 의도의 통제 요인으로 포함시켰다. 본 연구는 온라인 소비자 설문조사를 통해 자료를 수집하고 구조방정식 모형을 활용하여 분석하였다. 그 결과 인지된 심각성과 자가격리 성향에 유의한 영향을 미치지만 온라인 쇼핑 의도에는 직접적인 영향을 미치지 않는 것으로 나타났다. 또한 온라인 쇼핑 의도에 대한 인지된 심각성의 영향은 자가 격리 성향에 의해 매개된다. 대조적으로, 인지된 취약성은 자가 격리 성향과 온라인 쇼핑 의도에 부정적인 영향을 미치며, 이는 COVID-19의 위협 하에서도 모든 소비자가 온라인 쇼핑을 기꺼이 하지 않는다는 것을 의미한다. During the coronavirus disease 2019 (COVID-19) pandemic, remote retail emerged as a feasible option for safe shopping. A significant increase in online and mobile sales has been reported based on secondary data, but few studies have focused on the psychological and cognitive factors that systematically affect consumers’ behavioral intention of shopping online. This study explores specifically the effects of the perceived severity of and vulnerability to COVID-19 on consumers’ intention to use online or mobile shopping. We also included consumers’ propensity for self-isolation as a mediator and subjective norm as a control factor for their intention to shop remotely. The data were collected through an online consumer survey and analyzed using structural equation modeling. The results indicate that perceived severity significantly affects propensity for self-isolation but does not directly affect online shopping intention. Additionally, the effect of perceived severity on intention to shop online is mediated by propensity for self-isolation. In contrast, perceived vulnerability negatively affects propensity for self-isolation and remote shopping intention, implying that not all the consumers are willing to shop online even under the threat of COVID-19.

구매기업과의 장기적 거래관계 형성을 위한 공급업체의 전략 수립에 관한 탐색적 연구

이윤숙(Younsuk Lee),신호정(Hojung Shin) 한국경영과학회 2008 한국경영과학회지 Vol.33 No.4

We explore the determinants of long-term relationship between the buyer and the supplier to help suppliers develope a strategy to build long-term relationship with their buyers. Based upon an extensive literature review, we propose three groups of independent variables which may affect long-term relationship, including (a) environmental factors (product complexity, product importance, source dependence, price sensitivity), (b) relational factors (trust, commitment, satisfaction, intention of expansion), (c) operational performance (quality, delivery, cost capability, technical knowhow). The buyer's actual period of relationship with its main supplier is used as a dependent variable. Using hierarchical multiple regression analysis, we empirically test hypotheses, analysing a sample of 290 manufacturing firms in the U.S. The statistical results indicate that the buyer's source dependence, price sensitivity and the supplier's commitment play a significant role in establishing long-term relationship between the buyer and the supplier. However, the supplier's cost capability and technical knowhow in operational performance negatively affect long-term relationship in contrast with our hypotheses. Due to this controversial result, we divide the sample group into dual sourcing and multiple sourcing environments and reconduct regression analysis in a post hoc manner. The findings show that the supplier's cost capability and technical knowhow are negatively associated with the length of relationship only in the multiple sourcing environment. The results may confirm that both parties' opportunistic behavior is more salient in the multiple sourcing environment than in the single sourcing environment.

Yin Shuyan(윤서연),Hojung Shin(신호정) 한국경영학회 2023 한국경영학회 통합학술발표논문집 Vol.2023 No.8

Comprehension of customer complaints is regarded as an essential factor for firms to recognize the service problem to recover the service. This study objective is to investigate the relationship between load factor, service failures, and customer complaints in the US airline industry by analyzing the panel data. In particular, the lagged effect and nonlinear relationship between load factor, service failure and customer complaints. The results reveal that the load factor has a positive effect on service failure. Furthermore, the load factor and the indicators of service failure which are airline cancellation, delay, and mishandled baggage have a lagged effect on customer complaints. Finally, the airline cancellations, delay, and load factor show the non-linear relationship with customer complaints in the airline industry. Contributions of this paper are twofold. First, the effects of load factor and service failures on customer complaints were able to be detected accurately, by using longitudinal data. Secondly, empirical results provide implications to the existing body of knowledge on service failure and service quality, and proposed findings can provide implications for airline management.

Al-based alloys have recently attracted considerable interest as structural materials and light weight materials due to their excellent physical and mechanical properties. For the investigation of the potential of Al-based alloys, a surface porous $Al_{88}Cu_6Si_6$ eutectic alloy has been fabricated through a chemical leaching process. The formation and microstructure of the surface porous $Al_{88}Cu_6Si_6$ eutectic alloy have been investigated using X-ray diffraction and scanning electron microscopy. The $Al_{88}Cu_6Si_6$ eutectic alloy is composed of an ${\alpha}$-Al dendrite phase and a single eutectic phase of $Al_2Cu$ and ${\alpha}$-Al. We intended to remove only the ${\alpha}$-Al phase and then the $Al_2Cu$ phase would form a porous structure on the surface with open pores. Both acidic and alkaline aqueous chemical solutions were used with various concentrations to modify the influence on the microstructure and the overall chemical reaction was carried out for 24 hr. A homogeneous open porous structure on the surface was revealed via selective chemical leaching with a $H_2SO_4$ solution. Only the ${\alpha}$-Al phase was successfully leached while the morphology of the $Al_2Cu$ phase was maintained. The pore size was in a range of $1{\sim}5{\mu}m$ and the dealloying depth was nearly $3{\mu}m$. However, under an alkaline NaOH, aqueous solution, an inhomogeneous porous structure on the surface was formed with a 5 wt% NaOH solution and the morphology of the $Al_2Cu$ phase was not preserved. In addition, the sample that was leached by using a 7 wt% NaOH solution crumbled. Al extracted from the Al2Cu phase as ${\alpha}$-Al phase was dealloyed, and increasing concentration of NaOH strongly influenced the morphology of the $Al_2Cu$ phase and sample statement.

폐기물 재활용업체의 매출 증대 방안 : 폐기물의 구분과 재활용 가치를 중심으로

이남경(Namkyung Lee),정다운(Dawoon Jung),신호정(Hojung Shin) 중앙대학교 한국전자무역연구소 2021 전자무역연구 Vol.19 No.1

연구목적: 폐기물의 재활용은 폐기 비용만을 발생시킬 수도 있는 폐기물을 재사용 가능한 제품으로 변환하여 환경 및 순환 경제에 도움을 준다. 재활용의 환경적 영향에 초점을 맞추어 재활용 기술 개발을 주로 연구해 온 기존 연구와 달리, 본 연구는 경제적 관점에서 재활용 업체의 운영적 측면을 고려하여 국내 폐기물 재활용 업체의 매출성과에 영향을 미치는 요인을 분석하고자 한다. 논문구성/논리: 폐기물 재활용 제품의 매출에 영향을 줄 수 있는 폐기물 구분(일반폐기물/지정폐기물)과 폐기물의 재활용 가치(높음/낮음)에 따라 매출액에 차이가 있는지 테스트하였으며, 폐기물 구분과 재활용 가치 간 상호작용 효과를 고려하여 정책적 시사점을 도출하였다. 결과: 폐기물 재활용 업체의 매출 성과는 폐기물 구분과 재활용 가치에 따라 유의한 차이를 보였다. 폐기물 구분과 재활용 가치 사이 상호작용 효과 분석 결과, 일반폐기물의 경우 재활용가치가 낮은 폐기물은 재활용가치가 높은 폐기물보다 매출액이 유의하게 낮았다. 반대로, 지정폐기물은 재활용가치가 낮은 폐기물이 재활용가치가 높은 폐기물에 비해 매출 성과가 유의하게 높게 나타났다. 독창성/가치: 본 논문은 재활용률 향상에 초점을 맞추었던 기존의 폐기물 재활용 연구를 확장하여 재활용 업체의 매출 성과를 다양한 종류의 폐기물에 대해 분석하였다. 이를 통해 영세한 규모로 운영되고 있는 국내 폐기물 처리업체의 수익성 향상을 위해서는 폐기물 구분과 재활용 가치에 따른 선별적 지원이 필요함을 밝혔다. Purpose: The recycling industry is beneficial to both the environment and firms because recycling adds value to waste, which otherwise raises disposal costs. Previous studies have mostly focused on the impact of waste on the environment and ways of increasing the recycling rate. This paper broadens the literature by focusing on the operations of recycling firms and examining the factors influencing the sales of recycling firms in Korea. Composition/Logic: This paper tests if sales difference depends on the type of waste (regular/special) and the recycling value (low/high) of waste. Then, the interaction between the type of waste and the recycling value of waste is also tested to draw implications for the recycling policy. Findings: Using ANCOVA, it is found that both the type (regular/special) and the recycling value (high/low) of waste should be considered to explain the sales difference of recycling firms. For regular waste, low-value waste has lower sales than high-value waste despite the significantly higher sales volume. For special waste, low-value waste has higher sales than high-value waste because the sales volume compensates for the value difference. Originality/Value: This study takes the operations of recycling firms into account to explain the sales of recycling firms. It also considers different types of waste to generalize the result. The findings suggest that a recycling policy should be selective considering the type and the recycling value of waste.

택시서비스 품질 저하의 선행요인들에 관한 실증적 연구

이상준(Sang Joon Lee),이윤숙(Younsuk Lee),신호정(Hojung Shin) 한국경영과학회 2015 한국경영과학회지 Vol.40 No.4

Taxi, one of the passenger services, is an essential transportation system in our society. In spite of the importance of taxi service, deterioration of the service quality is continuously reported. In particular, taxi service failures due to traffic accidents have emerged as the most serious social problem which may incur a considerable amount of social costs. In this study, we focus on analyzing the causes of service quality deterioration- traffic accidents of both corporately owned and privately owned taxies in Seoul. The research objective is to find out the determinants of service quality deterioration of Taxi industry and to suggest policies for improving the taxi service in Seoul. We collected the archival data from KTSA (Korea Transportation Safety Authority) and ODP (Open Data Portal), which span from 2005 to 2014. Hierarchical regression analyses and a set of mediation tests are conducted. The root factors inducing traffic accidents of taxies are divided into competitive, and profitability factors. The statistical results indicate that the accident ratio per taxi is not only affected by competitive/profitability factors such as number of active taxi drivers, number of bus passengers, and taxi fare, but also mediated by the traffic violation ratio. To alleviate the current problems with taxi service in Seoul, we conclude that the number of taxies be reduced and the taxi fare be increased. Finally, we suggest several policies to improve the endemic taxi industry problems, over-supply and the low profitability by enhancing the linkage between service quality and profitability.

공급기업과 구매기업의 공급사슬계약 체결은 서로의 이익을 증진시키기 위한 효과적인 방안이다. 본 연구는 공급사슬 상에서 이루어지는 공급기업과 구매기업간의 상호 협력을 위한 계약관계에 대하여 경영환경의 요인들이 미치는 영향에 관한 연구이다. 본 연구에서는 뉴스벤더 모형(the newsvendor model)을 기반으로 한 여러 가지 계약방식들에 대해 다양한 경영환경 변수들 - 수요의 변동성, 공급기업과 구매기업의 교섭력, 그리고 공급사슬 전체의 수익성 - 이 구성하는 각각의 조건 하에서 어떠한 계약방식이 다른 계약방식들보다 더 많은 이익을 가져다주는지에 관해 고찰하였다. 매개변수들의 조합을 통해 구성된 45가지의 다양한 경영환경 하에서 난수생성을 통해 수요를 발생시켜 각 계약방식들에 대한 시뮬레이션 결과를 도출하였다. 이 실험을 통해 환경의 변이에 대한 각 계약의 수익성과 및 계약 성공여부를 추산하였다. Supply chain contracts in general are known as an effective vehicle for coordinating supply activities between the supplier and the buyer, minimizing the negative influence of double marginalization. However, in the literature, there has been little understanding of how different contracts would perform in various environmental conditions. Using a series of systematic simulations, we extensively investigate the efficacy and risks of supply chain contracts, including revenue sharing, buyback, and sales rebate contracts. The analytical results confirm that the supply chain contracts have managerial properties as a mediator for supply chain coordination. The results also show that the performance of each contract is influenced significantly by the environmental factors.

서비스 실패 및 고객불만이 기업의 재무성과에 미치는 영향에 관한 실증적 연구

박수훈(Soohoon Park),이윤숙(Younsuk Lee),신호정(Hojung Shin) 한국생산관리학회 2011 한국생산관리학회지 Vol.22 No.1

본 논문에서는 서비스 실패 및 고객불만과 기업의 재무성와의 관계를 조사하였다. 공시된 미국 항공사 자료를 바탕으로 독립 변수인 정시운항률, 결항률, 수하물 취급문제, 항공권 초과판매의 서비스 실패와 고객불만이 종속변수인 기업의 ROA와 ROS에 미치는 영향력을 살펴보았다. 분석에는 PCSE(Panel Correlated Standard Error)패널자료 분석법을 사용하였다. 분석 결과 결항과 고객불만은 기업의 재무성과에 부정적인 영향을 미치는 것으로 나타났다. 특히, 고객불만 변수는 시간차를 두고 재무성과에 부정적인 영향을 주는 것으로 나타났다. 이 결과는 고객불만이 제기 되었을 때 적절한 보상 및 회복 활동이 이루어지지 않은 방치된 불만은 향후 서비스 선택 시 고객의 서비스 전환을 촉진시키고 이는 궁극적으로 기업의 재무성과에 부정적인 영향을 준다는 것을 시사한다. In this study, we explore the effects of service failures and customer complaints on the financial performance of service firms, analyzing the panel data from the U.S. airline industry. We collect the data from the Department of Transportation and the Bureau of Transportation Statistics. Specifically, the independent variables under investigation are arrival on-time, flight cancellation, mishandled baggage, over-sales, and customer complaints. Firm performance as a dependent variable is measured by both ROA and ROS. The statistical association between the independent and the dependent variables are established by a PCSE (Panel Correlated Standard Error) estimation method. The results show that service failures and customer complaints affect the financial performance negatively in general, but not all the failures demonstrate such a negative association with firm performance. In addition, the results indicate that the lagged impact of customer complaints are stronger on the firm performance than the current effect, implying that the negative influence of customer complaints intensifies in the future.
