Abstract:	本研究主要的目的為探討台灣中小企業市場佔有率的決定因素，並進一步分析製造業與服務業決定因素的差別。主要研究樣本使用行政院主計處2011年台閩工商及服務業普查資料，實證方法使用OLS最小平方法做迴歸模型，依照文獻與假說，將決定因素分為:市場結構的進入障礙、市場結構的進入誘因、創新活動與市場結構和其他影響因素等這四類衡量分類。實證結果發現，在全體產業樣本下，進入障礙中衡量規模經濟的變數:中小企業相對勞動生產力為正向影響，中小企業相對資本生產力為負向影響，表示中小企業競爭力主要表現在勞動而非資本的效率上。產品差異化的自有品牌、市場集中度指標為負向影響，符合假說。而進入誘因中的獲利率和創新活動中的研發密集度、電子商務以及其他影響因素中的產業年齡、勞動報酬與環保支出皆為負向影響，符合假說。除了衡量資金優勢的資本密集度為正向影響，不符合假說，表示可能在台灣整體產業下，較高的資本密集度並不全然是中小企業的不利因素。最後為製造業與服務業的差異部分，明顯兩樣本在資本相關變數上有很大的不同，服務業相對資本生產力不顯著，表示資本效率不是服務業的進入障礙，資本密集度為正相關、研發密集度為正相關，皆顯示服務業中小企業在資本的表現上優於製造業。 The purpose of my dissertation is to discuss the determinants of SMEs'' market share in Taiwan and also want to know the difference between manufacturing and service’s sample. In this study, I use the DGBAS 2011 Business Census’s data to build up the regression model and use OLS as empirical method. According to the literature and hypothesis, I classify the determinants in four aspect: entry barriers, entry incentive, innovation and other influence. Empirical result show that in whole industries sample, SMEs’ relative labor productivity, we use to measure the entry barriers, is positive significant and SMEs’ relative capital productivity, we also use to measure the entry barriers, is negative significant. It means the Competitiveness of SMEs is higher on labor force, not on the capital. Like other variable as,Self-brand, market concentration, profit ratio-use to measure the entry incentive, R&D and E-commercial-use to measure the innovation, firm’s age, relative wage rate and preventing pollution expenditure-the other influence are all negative significant. These determinants are fit in with hypothesis. However, the industry capital-labor ratio is positive significant. It is not fit in with the hypothesis. Maybe now days in Taiwan industry, higher capital investment is not an entry barrier in SMEs. Finally, in the difference between manufacturing and service part, it is obvious that they have a difference in some determinants measuring by capital. In services, SMEs’ relative capital productivity is insignificant. It means that capital efficiency is not a SMEs’ entry barrier. In addition, Industry capital-labor ratio and R&D is positive significant. They show that in services, SMEs have a better development comparing with manufacturing.
