摘要

本研究提出投資機會假說與自由現金流量假說，利用事件研究法檢視1999年到2005年間台灣上市上櫃公司中不同經營型態（專業經營vs.多角化）的公司，宣告發行普通公司債後的股東財富效果。實證結果發現台灣上市上櫃公司宣告發行普通公司債後，專業經營公司有正的標準化累積超額報酬，但多角化公司宣告期間的累積超額報酬表現並不明顯，此實證結果支持投資機會假說。另外，本研究也進一步發現，當一成長機會低且自由現金流量高的多角化公司宣告發行公司債時，市場負面評價較不明顯，此結果顯示對代理問題較嚴重（成長機會低且自由現金流量高）的多角化公司而言，舉債可有效控制代理成本，並可有效提升公司會計績效。

Literature indicates that the multiple-segment firms have higher free cash flows and lower growth opportunities compared to the single-segment firms. It also has been long recognized that leverage helps control the agency costs problem associated with potential corporate over-investment. Based on these findings, two hypotheses, including free cash flow and investment opportunities hypotheses, are proposed in this study to examine the effects of the different organization forms (single-segment vs. multiple-segment firms) on the announcement of public debt offering by Taiwan public traded firms between 1999 and 2005. Free cash flow hypothesis expects that announcement effect of debt offering is more positive for multiple-segment firms than for single-segment firms because the potential for debt offering to reduce over-investment problem should be higher for multiple-segment firms than for single-segment firms. However, single-segment firms on the other hand are predicted to have higher announcement return of debt offerings under the investment opportunities hypothesis. We find that consistent with the investment opportunities hypothesis, the stock market's responses to the announcement of public debt offering are more favorable for single-segment firms than for multiple-segment firms. The overall findings after several robust checks suggest that leverage works to lessen the overinvestment problem for multiple-segment firms.
