본 논문에서는 기존 연구에서 거의 고려되지 않았던 산업재 물류에서 납품공급업체가 지각하는 물류환경 불확실성과 고객중심역량, 자원중심역량, 정보중심역량 등의 물류역량이 물류서비스와 신뢰를 통하여 물류성과에 미치는 영향을 분석하는 것을 주된 연구목적으로 하였다. 위의 연구목적을 달성하기 위하여 H중공업 및 HSD엔진에 원·부자재를 납품하는 232개의 납품공급업체로부터 자료를 수집하여 연구가설을 검정하였다. 구조방정식 모형 분석을 통해 알아낸 분석 결과를 연구주제별로 살펴보면 다음과 같다. 산업재 물류에서 환경이질성과 환경역동성의 환경불확실성은 기대와는 다르게 재고가용성, 적시성 등의 물류서비스에 유의적인 영향을 주지 못하는 것으로 나타났다. 물류역량은 구성요인의 특성에 따라 차별적인 효과를 나타내었다. 고객중심역량에서 반응성은 직접적으로 물류서비스와 신뢰에 유의한 영향을 주었고, 또한 물류서비스와 신뢰를 매개로 하여 물류비용절감, 배송의 질 등의 물류성과에 유의한 영향을 주었다. 반면에 고객중심역량 중 평판은 기능적인 측면의 물류서비스에는 유의한 영향을 주지 못했지만, 행위적인 측면인 신뢰를 매개로 하여 물류성과에 유의한 영향을 주었다. 자원중심역량인 물류 거래특유투자, 수송서비스 능력 등의 물류자원능력은 물류서비스를 통하여 물류성과에 유의한 영향을 주었다. 예상과 다르게 정보중심역량에서 LIS 등의 물류정보화는 물류서비스와 신뢰에 유의한 영향을 주지 못하는 것으로 나타났으나, 반면에 정보공유는 기능적 측면에서는 물류서비스를 매개로 또한 행위적 측면에서는 신뢰를 매개로 하여 물류성과에 유의한 영향을 주었다. 매개변수 역할을 하는 물류서비스와 신뢰는 물류성과에 모두 유의한 영향을 주는 것으로 검증되었다. 마지막으로, 본 논문에서 밝혀진 물류환경, 물류역량, 물류서비스, 신뢰 및 물류성과 간의 연관관계에 대한 분석결과들은 산업재 납품공급업체들에게 이론에 근거한 전략적 물류관리 실천방안으로 활용될 수 있을 것이다.
In Korea, industrial logistics studies between industrial suppliers and buyers are rare in academics in spite of its importance in logistics field and for practitioners. The major purpose of this study is to investigate the impact of logistical environmental uncertainties and logistics capabilities mediated by logistics services and trust on logistics performance in industrial products. Specifically, first, this study verifies the impact of logistical environmental uncertainties such as dynamism and heterogeneity on logistics services such as product availability and timeliness. Second, we test the effects of customer-focused logistics capabilities such as responsiveness and reputation on logistics services and trust. Third, the effects of logistics resources competence are examined on logistics services. Fourth, the impact of information-focused logistics capabilities such as Logistics Information Systems and information sharing on logistics services and trust are verified. Finally, we investigate the direct effects of logistics services and trust on logistics performance and also the mediating role of logistics services and trust between logistics capabilities and logistics performance. To empirically verify the proposed research model shown in <Figure 1> and the thirteen hypotheses, the 232 supplier data were collected from the vendors who supply parts/materials to the H Heavy Industries & Construction and HSD Engine as major customers. Specifically, the following thirteen research hypotheses were validated. H 1: As the level of environmental heterogeneity perceived by suppliers is increased in industrial logistics, the level of logistics services provided by suppliers will be lowered. H 2: As the level of environmental dynamism perceived by suppliers is increased in industrial logistics, the level of logistics services provided by suppliers will be lowered. H 3: Responsiveness of suppliers in customer-focused logistics capabilities will increase the level of logistics services provided by suppliers. H 4: Responsiveness of suppliers in customer-focused logistics capabilities will increase the level of trust between suppliers and buyers. H 5: Reputation of suppliers in customer-focused logistics capabilities will increase the level of logistics services provided by suppliers. H 6: Reputation of suppliers in customer-focused logistics capabilities will increase the level of trust between suppliers and buyers. H 7: Logistics resources of suppliers in resource-focused logistics capabilities will increase the level of logistics services provided by suppliers. H 8: The level of logistics information systems of suppliers in information-focused logistics capabilities will increase the level of logistics services provided by suppliers. H 9: The level of logistics information systems of suppliers in information-focused logistics capabilities will increase the level of trust between suppliers and buyers. H 10: The level of information sharing between suppliers and buyers in information-focused logistics capabilities will increase the level of logistics services provided by suppliers. H 11: The level of information sharing of suppliers in information-focused logistics capabilities will increase the level of trust between suppliers and buyers. H 12: The level of logistics services provided by suppliers will increase logistics performance. H 13: The level of trust between suppliers and buyers will increase logistics performance. The following results were verified using structural equation modeling using LISREL. First, environmental uncertainties such as dynamism and heterogeneity unexpectedly had insignificant effects on logistics services such as product availability and on-time delivery. This lack of significance might be due to power imbalance of small industrial vendors compared with large buyers. According to conflict spiral theory, small vendors do not have conflict with big buyers because of power imbalance. So, vendors who have stable transaction relationships with powerful buyers are not influenced by environmental uncertainties. That leads to insignificant environmental dynamism and heterogeneity effects on logistics services. Second, responsiveness in customer-focused logistics capabilities directly had significant impact on logistics services and trust. And also responsiveness had indirect impact on logistics performance such as logistics cost reduction and delivery quality mediated by logistics services and trust. Reputation in customer-focused logistics insignificantly affects logistical services in a functional aspect but significantly affects trust in a behavioral aspect. Since vendors with favorable reputation could decrease search costs and monitoring costs of buyers, buyers will trust vendors with positive reputation. Third, supported by resource-based theory, logistics resources such as logistics-specific investments and transportation service competence significantly impacted on logistics services that eventually leads to logistics performance. Fourth, consistent with prior studies, information sharing in information-focused logistics capabilities had significant effects on logistics services and trust. On the other hand, Logistics Information Systems did not. This is partially due to lack of LIS inefficiency in small heavy industry vendors. Fifth, consistent with previous studies, logistics services and trust between industrial suppliers and buyers directly did have significant effects on logistics performance such as delivery consistency and lead-time reduction. Also, the mediating role of logistics services and trust was supported between logistics capabilities and logistics performance using mediated regression. Sixth, above all, industrial vendors` flexible responsiveness and information sharing with buyers are the most important logistics capabilities to enhance logistics services and performance. Finally, the empirical results in this study could be strategic logistics management guidelines based upon the theoretical relationships among the environmental uncertainties, logistics capabilities, logistics services, trust, and logistics performance.
