| Summary: | 博士 === 東吳大學 === 經濟學系 === 93 === The resurgence of U.S. economic growth in the 1990s has generated considerable attention with many studies reporting a substantial impact from both the development and the use of information and communication technology (ICT). Many researchers all refer American long-run economic expansion to “New Economy”. Stiroh(2001) showed that the difference between ICT capital and non-ICT capital was that ICT capital would result in spillover effects.
Our purposes of this paper, first, were that we modified the dynamic factors demand model on the papers of Nadiri and Prucha(1990,1999) in order to include the ICT capital, ICT capital’s spillover and the effect of forward- and backward-linkage in input-output table into dynamic factors demand model. Second, we construct an ICT inputs database of manufacturing industries in Taiwan. Finally, our empirical analysis shows the following results. First, ICT capital and ICT capital’s spillover effects will save the inputs of intermediate materials and non-ICT inputs, but increase the demand of ICT labors. Second, the backward-linkage effects of ICT capital’s spillover are greater than the forward-linkage effects of ICT capital’s spillover. Third, the negative effects of ICT capital’s adjustment costs to output will be great when the spillover effects are negative. Fourth, we can decompose the total factor production into scale effects, effects of adjustment cost, spillover effects and pure technical progress. Fifth, the sources of output growth in manufacturing industries of Taiwan are scale effects, ICT capital, ICT labor and technical progress in order.
