摘 要 當前，中國大陸科技產業之生產品質和複製技術不斷升級，而兩岸 科技產品亦皆以世界巨大自由市場－歐盟為主要外銷市場之一，引發台 商科技產業赴中國大陸投資生產是否會造成台灣科技產品於歐盟市占率 被中國大陸取代的疑慮。本文蒐集融合時間序列與橫斷面的資料，採用 固定效果模型(fixed-effect model)，解析2000~2008 年之台商科技產業大 陸投資累計比重對台灣科技產品於歐盟市占率的影響。實證結果顯示台 商科技產業中，電力設備製造業、電腦及光學製造業、運輸工具製造業 與機械設備製造業在中國大陸的累計投資比重增加，導致歐盟市占率降 低；電子零組件製造業的情況則相反，在中國大陸累計投資比重增加， 歐盟市占率反呈擴張趨勢。
Abstract Today, the manufacturing quality and replication skills of high-tech products or materials in China is continuously improving. And E.U., the largest economy entity in the world, is still the main market for both China & Taiwan to export the high-tech products. Therefore, it is a great concern for Taiwanese market share in E.U. if Taiwanese high-tech firms continue to invest in manufacturing in China. This study adopted fixed-effect model to analyze Taiwanese high-tech firms' investment in China vs. their market share in E.U. over the years of 2000~2008. The result showed that the investment of Taiwanese Electronic Units and Components Manufacturing in China has positive significant impact on its market share in E.U. and those of Taiwanese Electrical Equipment Manufacturing, Computers and Optical Products Manufacturing, Transport Equipment Manufacturing and Machinery Equipment Manufacturing in China has negative significant impact on their market share in E.U. due to the competition from China.
