從單獨報表與合併報表探討營建業之盈餘管理

Abstract

首先，本研究探討我國營建業上市櫃公司的盈餘管理行為。以2001年至2010年連續十年為研究期間，利用隨機性檢定，判斷營建業中是否存在盈餘管理之現象，結果證實營建業存在盈餘管理。 其次，本研究也探討2005年新七號公報「合併財務報表」修訂對盈餘管理行為的影響，利用盈餘偵測模型，觀察營建業盈餘管理行為的變化，分析單獨報表與合併財務報表間是否存在盈餘資訊落差。研究之主要結論如下： （1）整體營建業單獨報表與合併報表間的裁決性應計盈餘並未有顯著差異。但在2005年前單獨報表所呈現的裁決性應計盈餘均較合併報表為大，顯示單獨報表隱含較多盈餘管理資訊。 （2）公報修訂後，營建業母公司單獨報表與合併財務報表間的裁決性應計盈餘差異縮小，顯示第七號公報的修正，確實有助於提升財務資訊透明度。 最後，闡述以兩種不同報表為基礎的盈餘管理工具比較。根據實證結果，裁決性存貨及裁決性應收帳款二者是營建業管理階層喜好使用之盈餘管理工具。更深入發現，其管理階層在單獨報表中較合併報表更偏好使用裁決性應收帳款作為盈餘管理工具。

Firstly, this thesis studies the behavior of Earnings management for the Listed and On cabinet companies of Construction Industry in our nations. It adopts the samples with ten-year period from 2001 to 2010 in Taiwan Final Database (TEJ TAIWAN DB). Run test is executed to identify whether Earnings management are found at Construction business or not. The conclusion is true. Secondly, this thesis also study the influences on Earnings management about the revision of “Consolidated Fincial Statements”in new Seven bulletin. We use Earnings detection mode to observe the change about Earnings management behavior and analyze the information gap between Stand-Alone and Consolidated Financial Statements. Following are conclusions: (1)In general, no obvious differences for discretionary accruals between two kind of Statements. But the discretionary accruals shown in Stand-Alone are larger than those of Consolidated Financial Statements before 2005, which imply more private Earnings management. (2)When the bulletin revised, the discretionary accruals shrinks between both Statements. It means the revising of Seven bulletin is benefitcal to the transparency of finical informations. Finally, the tools using for Earnings management are compared. According to regression-simulation results, discretionary inventories and discretionary depreciation are preferred for the management board in construction building business. More deeply, they incline to use discretionary depreciation in Stand-Alone Statements than in Consolidated Financial Statements
