本研究應用迴歸分析,探討財務比率與臺灣上市食品公司經營績效的影響,以2008年1月1日至2013年12月31日的季資料為單位共24季,公司數共有20家,總計480筆資料,以16個財務比率針對經營績效ROA和ROE進行相關性研究。 實證結果發現R-square分別為0.9348和0.9109解釋能力良好,有11個變數對ROA達到5%的顯著水準、7個變數對ROE達到5%的顯著水準,其中對ROA和ROE共同達到5%的顯著水準的財務比率,呈現正向關係的變數有稅前純益佔實收資本比率、營業毛利率、營收成長率,呈現負向關係的變數有應收款項週轉率、資產總額,從實證結果中可以得出財務比率對於經營績效有相當的影響性,期盼公司經營者可針對此財務比率加以關注,對於公司績效將有正面顯著成長。
This study adopts the financial ratio analysis method to conduct correlation coefficient analysis on sample data, unit root test on data stability, residual analysis, and regression analysis to conduct this study. Focusing on the investigation of the effect of financial ratio and the operating performance exchange listed food companies in Taiwan, using a total of 24 months’ seasonal data from 1st January 2008 to 31st December 2013 as units, after eliminating incomplete data, 20 companies are left, with 480 items of data. Focusing on operating performance ROA and ROE in conducting regression analysis through 16 financial ratios, the R-square is 0.9348 and 0.9109 respectively, indicating high ability. 11 variables reach the significant level of 5% for ROA, and 7 variables reach the significant level of 5% for ROE, of which both ROA and ROE reach the significant level of 5% in financial ratio, variables showing positive correlation have net profit before tax to actual capital ratio, operation gross profit and revenue growth rate, while variables showing negative correlation have average receivable turnover ratio and total assets. It can be concluded from the results of the experiment that financial ratio has a certain degree of impact on operating performance. We hope that companies’ operators can pay more attention to this financial ratio, as it will generate significant growth in the companies’ performances.
