Modeling electronic service acceptance of an e‐securities trading system

The purpose of this paper is to consider the technology acceptance model (TAM) in the context of internet securities trading. It examines the antecedents of perceived usefulness and explores the role of trust and attitude of securities investors toward usage. The behavioural intention of investors to use the internet securities trading service is influenced by perceived usefulness, attitude toward usage, and trust.

The paper uses survey research to explore the determinants in the e‐securities trading acceptance model.

The findings show five antecedents have a positive impact on perceived usefulness. These are ease‐of‐use, information quality, accessibility, trust, and flow control of the securities trading process. Respondents identify the highest benefit as the flow control of the securities trading processes via the internet channel.

The results suggest that investors prefer to have the freedom to control the details of the process when trading securities. In addition, trust is important for all levels of the TAM process. Trust has a large impact which is mediated through both perceived usefulness and attitude toward usage. There is a weaker direct impact on intention to use.

This paper includes a more comprehensive measurement of the antecedents of perceived usefulness such as ease‐of‐use, information quality, accessibility, flow control, and trust. It also demonstrates the importance of trust in explaining the psychological attitudes toward the service.
