Abstract
The purpose of this study is to find major factors to enhance public acceptance of a variety of technologies or its products by using multiple regression analysis, and to classify them by use of cluster analysis. The results are as follows. First, it was found that three factors identifiable as “the necessity”, “the beneficialness to the global environment” and “the trust in the enterprise” are useful variables for multiple regression analysis. Second, it was also discovered that cluster analysis made it possible to classify each matter roughly into two groups. One group was regarded as positive group, and another group was regarded as negative group.
