This article argues that Dr. Sun Yat-sen's Three Principles of the People, and its guiding influence on Chiang Kai-Shek and Chiang Jing-Guo's economic policies, is the main reasons for Taiwan's Economic Miracle. Past, studies of Taiwan's economic development identified three ideologies which produced Taiwan's economic development: The Three Principles of the People(Principle of Mínsheng), Nationalism (Developmental State and the China Factor), and Liberal capitalism. But most authors believed these ideologies were used to correct and prefect the market system. However, development does not automatically lead economic equality. This article argues that in order to achieve balanced economic growth, Chiang Kai-Shek and Chiang Jing-Guo carefully selected bureaucratic leaders who had a similar developmental vision. Additionally, the two leaders also implemented special policy measures designed by Sun Yat-sen's Thinking to produce balanced growth. Taken together, these two factors provide a more comprehensive explanation of Taiwan's economic success.
