上游廠商銷貨和下游客戶重編之關聯性：供應鏈夥伴之實證研究

Upstream Supplier Sales and Downstream Customer Restatement: Evidence from Supply Chain Partners

在此供應鏈網絡日趨重要之時代，由於客戶和供應商間之關係同為供應鏈管理之一環，有許多因素會影響供應鏈夥伴關係。過去已有研究探討銀行對貸款客戶宣布財務報表重編後之反應（Files and Gurun, 2018），雖然銀行和供應商皆視為其客戶的債權人，過去文獻並無探討主要客戶之財務報表重編對供應商銷售的影響，亦無研究探討重編型態（大重編和小重編）在供應鏈夥伴關係間所扮演的角色。據此，本文發現，當主要客戶進行大重編（更正重大的前期會計誤述）相較於進行小重編（非重大的前期會計錯誤，累積至當期成為重大誤述所做之修正），供應商會明顯減少對於該客戶之銷售占比。本文之研究成果，希望能提供權責機構、投資人、債權人、和供應鏈夥伴，對於財務報表重編的影響，能有不同層面之瞭解。

Given the growing importance of supply chain in today’s economy, research in supply chain management increasingly adopts a network perspective that emphasizes the interdependence between upstream suppliers and downstream customer. Prior studies, such as. Files and Gurun (2018), find that banks increase loan spreads after borrowers announce financial restatements. Although banks and suppliers are both perceived as creditors, extant research does not examine whether a restatement by a major customer affects a supplier’s sales decision and whether the restatement types (e.g.,“Big R”and“Little r”) can influences supply chain partnership. The results document that after a major customer discloses a misstatement correction through“Big R”(i.e., a material error that weakens reliance on previously issued financial statements and must be corrected and disclosed retrospectively through restatements) rather than“Little r (i.e., corrections of errors that were not material to prior period financial statements, but accumulate to a material amount in the current period), the supplier will reduce the percentage of total sales attributed to the customer substantially. The findings are useful for accounting regulators, investors, creditors, and supply chain partners by providing them with insights on the effects of accounting restatement from a different perspective.
