Abstract
Most of the countries in the world take the position of managing separation of government agency and enterprise for the purpose of enhancing the efficiency and competitiveness. In the perspective of Taiwan, the system of harbors management is a combination of administrative supervision and business administration. In order to keep up with the global trend of corporatization, Taiwan International Ports Corporation (TIPC) was established on March 1, 2012, responsible for the management and operation of the ports. In the beginning of the transformation, Taiwan International Ports Corporation resolved to invest in new businesses or set up constituent corporations except for maintaining traditional ports operation. Moreover, the current human resource was best relocated for financial maximization and competitive effects. For TIPC, diversification is a 100% sure direction to move forward. However, the key factors to succeed depend on how to estimate various investments and handle the issues of systems, regulations, budgets, coverage of sales, and so on under restricted conditions. The research focuses on the cases of diversification managements of major port holding groups all over the world for TIPC's reference. In addition to suggesting specific potential investments, the research covers the the evaluation of diversified investments, the organism of founding branch corporations, the administration and control of reinvestments.
