From a Supplier to a Retail Controlled Supply Chain: What are the Impacts on Transport Demand? From Data Analysis to Model Development

One of the core concepts in transport and economic geography states that transportation is a derived demand, for both passenger and freight transport. There also exist considerations of logistic matters as endogenous variables for economic strategies. Therefore, understanding freight demand requires a close analysis of the factors that influence individual decisions. Collecting the necessary data is difficult though, due to the great heterogeneity of decision makers and the complexity of the decision-making process as well as the interdependency of the various actors. It is the aim of this research to contribute to understanding these interdependencies. A new systemic view on the interaction of actors and their influencing factors are provided. The results of the research allow for the development of indications for quantitative survey and additional for the modeling of changes in market structures on transportation demand.
