Understanding the antecedents of car sharing usage. An empirical study in Italy

Purpose: Sustainable mobility and collaborative consumption are debated issues in the literature. In this field, car sharing (CS) represents a growing tendency that attracts interest by academicians for its potential positive impact on sustainability. This study aims to understand the main drivers of CS usage, unveiling the role of service quality and the possible inhibitors. Design/methodology/approach: Based on theoretical assumptions in the literature, the authors developed a theoretical framework that aims at understanding the main antecedents of CS usage. An empirical investigation involving the city of Rome (Italy) was performed. The study presents a qualitative and quantitative survey, while the proposed theoretical model has been tested through structural equation modelling statistical techniques. Findings: The findings show that usefulness positively affects the intention to use CS services. Moreover, the green attitude and expected service quality indirectly influence the intention to use CS services impacting perceived usefulness. The results show that the expected service quality has a strong influence on usefulness, whereas green attitude has a weaker influence on usefulness. The intention to use CS services is directly influenced by the usefulness and inhibitors that affect it negatively. Originality/value: The originality of this paper lies in the fact that this study discloses the main antecedents of the intention to use CS services, emphasizing the role of service quality. This study provides fruitful insights to policy and decision-makers to understand how to improve the CS usage in the urban transport system of the city of Rome. It suggests developing a higher level of service quality in the vehicles, suitable technological applications and effective communication as well as on overcoming its main inhibitors.
