Therefore, the purpose of this thesis is to research on the effects of investment in ICT capital on other inputs in manufacturing firms in Taiwan. We will focus on whether there is skill-biased technology change (SBTC) especially after investing ICT capital. 　　Industry, commerce and service census in 1991 and 2001 are used in this study, we choose manufacturing from these datum as observations. This thesis builds on empirical framework on Dewan and Min (1997), and we adopt Allen partial elasticity of substitution (AES) as a research method to observe the impact on investing ICT capital. Furthermore, we use seemingly unrelated regression estimation (SURE) to estimate regression which investigate factors that are related to the degree of AES. 　　Our main finding is that there is some empirical support that investing ICT capital causes SBTC in manufacturing in Taiwan. In 2001, ICT capital is a substitute for both Non-ICT capital and unskilled labor, but it is a complement for skilled labor on the other hand. Further, we find that average firm size, HHI, and the degree of capital intensity will affect the degree of AES in different industries.
