Using the data base of Taiwan Economic Journal from the year 1998 to 2005.This thesis adopt panel data estimation methods, including pooling data, the fixed effect and the random effect technique. Hausman test is used to determine the appropriate estimation method in the empirical study. The empirical results are listed as follows. 1.For the industry, salary and capital have a significant positive impact on productivity. R&D and horizontal spillover tend to be substitute. 2.For upstream firms, salary, capital and R&D have a significant positive impact on productivity. Horizontal spillover has a significant negative impact. R&D and horizontal spillover tend to be substitute. 3.For medstream firms, capital, horizontal spillover and vertical spillover (upstream to medstream) have a significant positive impact on productivity. R&D has a significant negative impact. 4.For downstream firms, salary, capital, R&D and vertical spillover (upstream to downstream) have a significant positive impact on productivity. Horizontal spillover has a significant negative impact. R&D and vertical spillover (upstream to downstream) tend to be substitute. en_US DC.subject R& zh_TW DC.subject D zh_TW DC.subject 外溢效果 zh_TW DC.subject 生產力 zh_TW DC.subject 研發外溢垂直效果 zh_TW DC.subject R& en_US DC.subject D en_US DC.subject spillover en_US DC.subject productivity en_US DC.subject vertical R& en_US DC.subject D spillovers en_US DC.title 台灣半導體產業研發外溢垂直效果之實證研究 zh_TW dc.language.iso zh-TW zh-TW DC.type 博碩士論文 zh_TW DC.type thesis en_US DC.publisher National Central University en_US
