台灣經濟高度依賴對外貿易，經濟成長與出口成長的變化關係密切，但是近年來由於廠商大量對外投資，赴海外設立生產基地，特別是製造業中主要的資訊電子產業很多廠商到大陸設廠。因此部分人士認為海外生產係造成台灣出口不振，就業機會減少，產業空洞化的原因。但也有人認為這反而證明台灣在產業全球化、自由化及產業升級轉型的成功證明。 台灣對外投資從1987年開始蓬勃發展，1990年開放對大陸間接投資後，對外投資金額更是快速成長，也形成廠商大量海外生產的營運模式，這種現象到底對台灣就業市場造成何種影響？本論文主要研究海外生產會不會造成就業機會減少等產業空洞化現象？特別是對於製造業中海外生產比重越來越高的資訊電子產業而言，海外生產比率變動情形與該產業就業人數之間到底存在何種連動關係，對廠商勞工雇用又具何種影響？ 本論文研究發現資訊電子產業海外投資增加及外銷比例的提升，可以增加就業機會，但海外生產是造成勞工雇用減少的主因。資訊電子產業產品生命週期短，低附加價值製程應開放赴大陸或其他地區投資，高附加價值製程設法留在台灣生產；也就是將核心競爭力的關鍵技術或零組件保留台灣製造，以製程切割，垂直分工的模式開放對外投資，才能維持國內廠商的國際競爭力，提高產品附加價值，加強研發創新、品牌行銷，協助廠商在地升級及全球佈局，才能減少海外生產對國內勞工雇用的衝擊。 另外本論文建議，政府應該改善投資環境，輔導廠商在地升級，協助提升廠商全球運籌佈局能力，改善生活環境加強人才培訓，才能提升廠商競爭力，如此才能有效降低廠商海外生產的比率。 / Taiwan economy is highly dependent on its international trade -- economic growth is highly influenced by exports growth. Nevertheless, the increasing outward investment, especially the huge IT investments in China, may change this trend. Some people argue that overseas production is the key factor of slacked export, diminished job opportunities, and industrial hollowing-out, the other people insist that the above phenomenon is an evidence of Taiwan’s globalization, liberalization, and Industrial Upgrades. The Taiwan’s outward investment started from 1987, accelerated in 1990, the year that Taiwanese government lifted the ban against indirectly investing China and formed a new business model of “Taiwan Orders, Overseas （Chinese） Productions”. What is the influence of this new business model? Is this the root of diminished job opportunities and industrial hollowing-out? What’s the correlation between overseas production growth rate and unemployment rate in Taiwan IT Industry particularly? This article discovered the increment of outward investment and export ratio in IT industry could boost job opportunities; however, overseas production is the key factor to cause layoffs. As a result of short product life cycle characters, the low value-added IT production should apply open door policy while high value-added ones should be encouraged to produce locally and keep the core competency domestically. Keep the key component or technology manufacture in Taiwan will help create Taiwanese international competitiveness, increase added values, inspire research and innovation, direct brand marketing, upgrade industries levels, connect globally, and lower the impact of overseas production on employment. In addition, this article advised the government should cement Taiwanese companies’ international competitiveness and lower overseas production ratio by improving the investment climate, assisting local industries’ upgrades and the abilities of global logistics, improving living environment, and reinforcing manpower cultivation.
