如何藉由良好的公司治理機制與產業市場競爭以增強公司之運作績效，一直以來為廣受討論的議題。本研究選取台灣資訊電子業2005 年到2009年之上市公司為研究樣本，運用隨機邊界生產函數探討股權結構與市場競爭二大構面，對樣本廠商生產效率之影響程度。實證結果顯示：(1) 產品替代性和技術無效率存在顯著負向影響；(2) 董監事控制權偏離程度對於不同的經營績效衡量指標，則有不完全一致的結論；(3) 董監事規模與股份盈餘偏離程度，對於技術無效率存在顯著正向影響；(4) 經理人持股比率與法人持股比率，對於技術無效率存在顯著負向影響。

It is well documented in the literature that how to improve the performance efficiency of companies by proper corporate governance mechanism and industry market competition. The companies included in this sample are listed companies of Taiwan’s electronics and information industry between year 2005 and 2009. This study applies a stochastic frontier production function to investigate the effects of the ownership structure and market competition on production efficiency. The empirical results show that: Product substitutability has a significantly negative effect on the production inefficiency. There is a not completely consistent conclusion which means that the divergence between the controlling power of the board and the voting rights of the controlling shareholder affect production inefficiency among various performance indexes. The board size and the magnitude of deviations from one-share-one-vote present significantly positive influence on production inefficiency. There exists a negative association between the stock ownership of managers, institutional ownership and production inefficiency.
