臺灣曾是以中小企業為主的出口貿易經濟體系，其對市場變動的敏感反應及靈活調度是促成臺灣的貿易、經濟成長快速的一大要因。目前各項政府統計資料對「出口」所涵蓋的意義及範圍有所差異，以及足以作為規模判定的變數不盡相同，因此，要瞭解中小企業出口的真相極具挑戰性，必須先從釐清各項調查資料的本質著手，進而觀察中小企業貢獻比率的變化，以及分析造成變化的可能因素，才能對中小企業出口貢獻作整體性分析，並對輔導政策提供具體建議。準此，本文的研究目的包括：（一）檢視各項統計資料對「出口」定義的差異。（二）分析中小企業各項出口通路之出口金額。（三）檢視出口金額變化和出口通路之關係。（四）分析中小企業出口貢獻比率下降之原因。茲僅就本研究最近一次調查結果摘要如下： 有關中小企業間接出口推估方面，根據調查結果顯示，2003年貿易商外銷貨品來自中小型製造商的比率為66.17％，而大型製造商在臺生產並出口的金額中，來自中小型製造商的投入金額占13.49％，另有關中小型製造業產品銷售通路結構方面的調查，有待未來進一步釐清。對於中小企業出口貢獻率下降原因的探討，綜合調查結果推論全球化發展可能是影響中小企業出口貢獻率下降的重要因素，特別是全球化發展較有利於大企業進行海外佈局，透過國際資源與通路的整合，減輕市場競爭與波動的衝擊，其具備較好的發展基礎與競爭力，進而帶動大企業直接出口的成長，進而可能導致中小企業出口貢獻率下降。

The sensitive reaction and agility towards market change of Small Medium Enterprises (SMEs) is one of the main reasons for Taiwan's fast trade and economic growth. Currently, “export” definitions and scopes of various governmental statistics are quite broad. Therefore it is a challenge to understand the truth of SMEs export. To make an overall analysis on SMEs export contribution, and provide concerete suggestions for counseling policy, beginning from clarifying the essence of various survey information is necessary. In this paper: 1) View the dedinition of various export statistical information. 2) Analyze SMEs various export ways and values. 3) Examine the relationship between export value change and of export ways. 4) Analyze the reason for SMEs export contribution rate decrease. Recent survey results are the following. In regard to SME's indirect export estimates, the ratio of trade export products in 2003 from SMEs is 66.17%. The ratio of large enterprises that manufacture and export products from SMEs in Taiwan is 13.49%, further research on SMEs manufacture product sale channels is recommended. Globalization may be the main influence for the decrease of SMEs direct export contribution rate, especially since globalization development is advantageous for large enterprises to setup overseas. Through the combination of international resources and distribution routes, the impact of market competition and undulation can be decreased for large enterprises, and thus results in better development basis and competitiveness. The above reasons encourage the grow of large enterprises' direct export rate, which are possible causes for the decrease of SMEs export contribution rates.
