Information Systems Technology Acceptance Process, The Level Of Information System Applications

In the field of user's acceptance of information systems (IS), technology acceptance model, based on social psychology, gains popularity. Present researches extend it into diverse aspects, which only take particular sofeware or information technology as their samples, with rarely consider the influence which caused by the difference of IS.The purpose of this research is to pursue better measures for predicting and explaining use. The investigation focuses on two aspects with structural equotation modeling method. One is to build the basic research framework from literature, including the main factors of technology acceptance model, to discuss if the model is proper in IS field and the changes. The other is to add two new factors, the depth and width in application of IS, to discuss their impact on the model.The findings include the following: firstly, customers' intention to use IS is positively affected by the perceived usefulness and perceived ease of use, with the relative strength of the usefulness-intention relationship. Meanwhile, the results suggest that ease of use may be an antecedent to usefulness. Secondly, the linkage between subjective norm and the main two independent variables in the model is significant, while compatibility only has a strongly influence to perceived ease of use. Thirdly, the variables' relationship varies in IS with different application width. If the IS is used in a wider range, the influence from usefulness to intention and the one from ease of use to usefulness will be enhanced, while impact from ease of use to intention will be weakened. Lastly, the results lessly support prior theory about the relationship between intention to use and actual usage.
