Abstract
In this research, we demonstrated the validation of e-commerce evaluation model using survey data of Japanese manufacturing and wholesale companies. Major findings are as follows: First, the evaluation model was validated because utilization of E-commerce and other drivers have significant impact to operational output such as rationalization of ordering process and reduction of inventory. Second, although the relationship between e-commerce and rationalization of ordering process is very clear in placing orders, it is not statistically significant in receiving orders. Third, we found that the leadership of top management in introducing e-commerce is very important to generate expected output.
