本研究主旨為探究貿易自由化對於企業創新表現的影響。利用台灣電子業上市與上櫃公司1990至2015年期間的廠商層面資料，創新的表現則是以企業每年的發明專利申請數量作為衡量。由於過度分散與零膨脹的問題，因此以零膨脹負二項模型進行估計。結果顯示，出口行為與加入WTO對於專利申請數的提升皆有正面影響，雖然我們不能肯定產生影響的具體機制為何，但在實證結果中我們發現貿易自由化促進廠商創新表現的情況確實存在於台灣電子產業中。

This thesis aims to investigate the effect of trade liberalization on firm innovation. We measure the performance of innovation by the number of patent applications at the enterprise level. The empirical analysis uses the firm-level data from Taiwan’s electronics industry from 1990 to 2015 combined with the patent data. Due to the problem of overdispersion and zero-inflation, we adopt zero-inflated negative binomial model in the empirical analysis. The results show that exports and accession to WTO have a positive impact on the number of patent applications. Although we can not specify which mechanism have dominant influence, our findings suggest that trade liberalization promotes innovation in Taiwan’s electronics industry.
