Lin Hsin-i (; born 2 December 1946) is a Taiwanese businessman and politician. He served in the Democratic Progressive Party administration as Minister of Economic Affairs between 2000 and 2002, then as Vice Premier between 2002 and 2004.[2]
In November 2005, while a Senior Presidential Adviser, Lin attended the Asia Pacific Economic Cooperation (APEC) forum in Busan, South Korea, in place of Taiwan's President Chen Shui-bian. Because of opposition from the People's Republic of China, Taiwan's senior leaders are unable to attend APEC events in person and must send a ministerial-level envoy. He was Chairman of the Industrial Technology Research Institute from 2004 to 2008.
A graduate of National Cheng Kung University, Lin was an executive in the car industry before entering politics.
