汽車工業仍是民生基礎工業，在過去也曾經是經濟成長的要角。 如今因國家產業政策及產業結構改變，使得產業產值占製造業比重下滑(民國98年占製造業2.7%)。 過去已成往事，放眼未來東協加三(中國，日本，韓國)若簽署完成，而台灣若不加入ECFA，許多製造業包括汽車工業會因關稅而失去競爭力。本研究以行政院主計處於民國75，80，85，90年等每五個年度所辦理之「台閩地區工商及服務業普查」資料，計算廠商的總要素生產力（Total Factor Productivity , TFP）以下簡稱TFP。並且進行統計分析和建構實證模型，分析影響汽車及其零件製造業TFP的主要因素，進而找出提升產業競爭力的方向。 經本論文基本統計結果分析如下(1).汽車製造業廠商家數有下滑的趨勢，汽車零件製造業廠商家數則呈現成長趨緩。 (2).汽車零件製造業HHI有增加的趨勢，這顯示市場規模偏向集中的情況。(3).兩個產業的資本勞動比皆有增加的趨勢，這顯示產業趨向資本密集的產業(4).零件製造業出口持續呈現穩定成長。而在實證結果方面(1).汽車製造業TFP逐年下滑，汽車零件製造則微幅上揚(2).汽車製造業的市占率與TFP有顯著正相關，廠齡與TFP則呈現顯著負相關(3)汽車零件製造業在出口方面與TFP呈顯著正相關。市占率，委外加工，廠齡則與TFP有顯著負相關。 關鍵字:總要素生產力;汽車製造業;汽車零件製造業。Auto industry is a fundamental industry for people’s livelihood. It had ever boomed Taiwan manufacture industry for a decade. Because of auto industry transition, the ratio of output of auto industry occupied on whole manufacture output is getting less, however it was gone away. Viewing on the future of this industry, if auto industry join ECFA ,it would be a good chance to boom this industry again. This dissertation use “industry ,commerce and service census” data (1986,1991,1996,2001)to calculate industry fundamental data(varies) and TFP with Good et al measurement of formula for TFP. The purpose of this dissertation is to run multiple regression to fine how varies impact on TFP. The most important of fundamental statics result on census are as follows:(1).The number of automaker is getting less and auto parts maker is growing slowly on relative high number comparing the past(2).The HHI of auto parts maker is increasing(3).Both of two industry of ratio between capital and labor is getting up(4).Export output of auto parts maker is increasing . The result of empirical testing are as follows:(1)The TFP trending of auto maker is getting down and the auto parts maker is growing slowly.(2)The market share of auto maker positively impact on its TFP apparently in contrast to age.(3)The export of auto parts maker positively impact on its TFP apparently in contrast to market share, subcont, age.
