Improvement of Sustainability by Vertical Supply Chain Collaboration at Logistics Service Providers : - A Multiple Case Study

Abstract: Background: Today’s organizations operate in a competitive and dynamic business environment in which the attainment of economic, social and environmental sustainability targets has become crucial for firms. Supply chain collaboration is considered as a strategic issue for the fulfillment of these targets. Thus, studies on supply chain collaboration for sustainability have increased, especially for manufacturing firms. However, there is a lack of research of the perspective of logistics service providers in this context, requesting scientific investigations. Purpose: The purpose of this thesis is to explore vertical supply chain collaboration between logistics service providers and their partners with regards to improving economic, environmental and social sustainability at logistics service providers. Method: Within this multiple case study and a deductive research approach, qualitative data from three logistics service providers is gathered by conducting interviews and analyzed. Firstly, each individual case is investigated by using an explanation building, and thereafter compared and generalized by means of a cross-case analysis. Findings and Conclusion: Considering the improvement of sustainability at logistics service providers, the research reveals that economic, environmental and social sustainability can be improved by vertical supply chain collaboration jointly conducted by logistics service providers and their key suppliers as well as key customers. However, strong interdependencies between the three sustainability dimensions are noticeable as they overlap in-between. Besides, the findings indicate that the executed vertical supply chain collaboration practices mostly have the potential to improve economic sustainability at logistics service providers. Environmental and social sustainability are less improved or sometimes even negatively affected.
