本研究主要探討盈餘重編宣告如何影響重編公司之供應商的股價評價與實質投資決策。首先，本研究假設並發現，盈餘重編宣告除了導致重編公司的股價顯著下跌外，亦誘發其上游供應商的股價顯著下跌。實證進一步發現，供應商的股價依盈餘重編之資訊內涵而調整，促使投資人關注重編事件對上游供應商的預期盈餘之影響，也提醒投資人去關心上游供應商的財務報表品質。其次，本研究假設，盈餘重編宣告傳遞有關重編公司未來前景不佳及財務報表不實的資訊，將影響其供應商對投入特定關係資產所能獲得收益之預期，進而影響其對重編公司所投入的特定關係資產投資決策。實證結果支持前述假說，重編公司之供應商於重編宣告年度後將減少其研究發展支出，且此研究發展支出之變動與重編宣告所引起的股價變動具顯著關聯性。最後本文假設，重編公司扭曲其實際盈餘數字將影響供應商的投資決策，進而影響供應商的投資效率性。研究發現，供應商在重編公司財務報表誤述期間有顯著超額投資之現象。然而，此供應商之超額投資現象在盈餘重編宣告年度後不再顯著。 / This dissertation extends prior research on earnings restatements by examining the effects of earnings restatements on valuation and investment decisions of restating firms’ suppliers. First, this paper hypothesizes and finds that earnings restatements that adversely affect stock price of the restating firms also induce their suppliers’ stock price declines. These stock price declines are related to changes in analysts’ earnings forecasts and seem to reflect investors’ financial reporting quality concerns. Second, I hypothesize that earnings restatements contain information about the value of relationship-specific investments by suppliers. This information causes suppliers to revise their belief about the value of relationship-specific investments, and therefore affects their subsequent relationship-specific investment decisions. Consistent with my prediction, I find that changes in suppliers’ relationship-specific investments after restatement announcements are related to information in the restatements. Finally, I predict and find that a restating firm misreporting financial results induces its suppliers to make excess investments during the misreporting period, while excess investment is no longer positive after the restatement announcement.
