Due to the rapid changes in global economic environments, enterprises have to continually enhance their business competitiveness. To improve business, planning educational training has been regarded as a channel to educate outstanding employees. Recently, most of the companies in the securities industry in Taiwan have adopted web-based educational training as a form of employee training. However, low e-learning acceptance on the part of employees is the essential obstacle when enterprises attempt to promote web-based continuing learning. Previous studies have shown that hardiness and Internet self-efficacy may be important factors that influence whether an individual will continue with web-based learning when facing pressure. Securities practitioners are required to deal with high pressure and persist in enhancing their professional knowledge in their working environment; therefore, continuing learning is crucial to maintaining the quality of professional service. The present study recruited securities practitioners as the research participants, and examined the effects of hardiness and Internet self-efficacy on their attitudes towards web-based learning when they were participating in web-based learning. The findings revealed that securities practitioners' hardiness and Internet self-efficacy both had direct positive effects on their attitudes towards web-based continuing learning. Meanwhile, their Internet self-efficacy had a mediating effect on the relationships between hardiness and attitudes towards web-based continuing learning.
