Within Top 1000 Corporate Rankings across the Taiwan Strait, the performance of Taiwanese enterprises is generally not good. With regard to this problem, the present author aims to identify and analyze it more profoundly. To this end, the business analysis method is here used to review performance indicators. Further, the system of Partial Least Squares (PLS) is employed with the purpose of exploring the critical patterns within the Top 1000 Corporate Rankings across the Taiwan Strait. According to the results of this study, it appears Taiwanese enterprises are going from bad to worse. Moreover, it also appears that, generally, Hong-Kong enterprises implement better business models than do Chinese or Taiwanese enterprises. Also, although Chinese and Taiwanese enterprises employ similar business models, the former show preferable performances. Hence, this is a critical time for Taiwanese enterprises to consider what to do next and how to proceed.
