本研究為對國內上市、上櫃公司採用減資策略對股價及經營績效之影響,研究期間為2002年1月1日至2015年12月31日。實證結果發現,上市、上櫃公司在彌補虧損減資後,不論是平均異常報酬(AAR)或累積平均異常報酬(CAAR),股價均呈現負面反應,表示公司在彌補虧損減資後有負向的異常報酬,而上市、上櫃公司在現金減資後,AAR或CAAR負相關多於正相關,表示公司在現金減資後可能有負向報酬。 本研究以多元迴歸檢驗兩種減資在宣告後三年對經營績效有否差異,實證結果發現採用彌補虧損減資之公司,其係數值-0.009,表示企業若採取減資彌補虧損,其經營績效為負向,而採用現金減資之公司,其係數值0.009,表示企業若採取現金減資,其經營績效為正向。
This research investigates the effect of domestic public companies’ capital reduction strategy on stock price and operating performance. The research period is between Jan.1st of 2002 to Dec. 31st of 2015. Empirical research findings show that after companies compensate for loss reduction, stock price react negatively in terms of both AAR and CAAR. This means that when the companies compensate for loss reduction, there will be a negative abnormal return. On the other hand, when public companies conduct cash reduction, AAR or CAAR’s negative correlation is greater than positive correlation. This means that if the company has cash reduction, there is a negative abnormal return. In this study, multivariate regression tests were used to assess the differences in operating performance over the three years after the announcement. Research result shows that when using capital reduction for cover accumulated deficits, public companies’ coefficient is -0.009, meaning with this method, the operating performance is a negative effect. However, when a company uses cash capital reduction, the coefficient is 0.009. This means that when using cash capital reduction, operating performance has a positive effect.
