Some studying indicate when the industry is competitive, managers will have more benchmarks to evaluate the corporate and employee performance. Industrial competition is benefit to corporate financial performance. The others think if the industry is more monopolistic, the corporate have more power to control the goods’ price and cost, take advantage of suppliers and customers. Industrial competition harms corporate financial performance. Refer to past studies, they ignore the influence of the corporate goods’difference and market mismatch. As the result, in my study, the calculation of market share is based on domestic market. The empirical study shows that market structure has significant effect on corporate financial performance. The corporate with higher market share will have better return of equity in the future. The market share have more influence on corporate with high import rate than corporate with high export rate. The difference of corporate export behavior will affect the empirical result. Market share have heavy influence on corporate with high import rate.目 錄 目錄.....................................................iv 表錄....................................................vii 第一章 緒論 第一節 研究動機與目的.....................................1 第二節 研究流程...........................................3 第二章 文獻探討 第一節 獨占力對廠商行為影響...............................4 第二節 獨占力對於企業財務績效影響.........................8 第三節 文獻探討小結......................................10 第三章 研究設計 第一節 資料蒐集與變數定義................................11 第二節 研究假說..........................................14 第三節 敘述統計..........................................16 第四章 實證結果 第一節 共線性分析........................................21 第二節 實證分析─所有樣本................................21 第三節 實證分析─內、外銷比率進行分組....................33 第四節 實證分析─產業別進行分組..........................41 第五章 結論 附錄.....................................................52 參考文獻.....................................................58525441 bytesapplication/pdfen-US市場結構廠商績效市場占有率產業競爭Market StructureCorporate PerformanceMarket ShareIndustrial Competitionthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/60722/1/ntu-94-R92723045-1.pdf
