本研究以民國79年至民國87年為研究期間，探討當景氣出現波動時，企業是否有操縱盈餘的行為。首先探討景氣循環對企業經營績效的關連性，觀察不同產業企業之經營績效是否因景氣變動而有所差異。其次針對景氣循環與企業盈餘管理程度之關連性進行研究，探討不同產業企業盈餘管理的程於景氣擴張期與收縮期有無顯著的差異。
實證結果顯示：(1)整體而言，景氣循環與全體樣本公司之經營績效呈顯著的正向關係，個別產業而言，紡織業、塑化業及建築業在景氣擴張時期之經營績效顯著優於收縮時期；(2)當以ODACA（以總資產及成長率調整後與營業有關之裁決性應計項目的變動取絕對值）作為盈餘管理之代理變數探討景氣循環與盈餘管理之關聯性時，就全體樣本公司而言，企業在景氣處於收縮期的盈餘管理程度顯著大於擴張時期，就個別產業之分析結果，食品業及塑化業盈餘管理的程度於景氣收縮時期明顯大於擴張時期；(3)當以ODACS（以淨銷貨收入及成長率調整後與營業有關之裁決性應計項目的變動取絕對值）作為盈餘管理之替代變數探討景氣循環與盈餘管理之關聯性時，以整體樣本來說，企業在景氣處於收縮期的盈餘管理程度顯著大於擴張時期，觀察個別產業之情形顯示食品業、電機業及塑化業盈餘管理的程度在景氣收縮時期明顯高於景氣擴張時期；(4)當以NOI（(以總資產調整後業外收益變動取絕對值）作為盈餘管理之替代變數探討景氣循環與盈餘管理之關聯性時，就整體而言，樣本公司在景氣處於收縮期以業外淨損益操弄盈餘的程度顯著大於擴張時期，依個別產業觀察，電子業、電機業及建築業在景氣收縮時期利用業外損益管理盈餘的程度顯著高於擴張時期。
關鍵字：盈餘管理、經營績效、景氣循環 / Focusing on the firms listed on Taiwan Stock Exchange over the period of 1990 to 1998, this thesis investigates whether the sample firms manipulate earnings in the face of business cycle. First, this thesis examines the association between business cycle and corporate operating performance. Furthermore, it explores the relationship between business cycle and the magnitude of earnings management.
The empirical results document that 1) business cycle is positively and significantly associated with the whole sample firms' operating performance and the relationship is founded in textile industry, plastic-chemical industry and construction industry. 2) When using the absolute value of changes of operating discretionary accruals adjusted by total assets and growth rate (ODACA) as a proxy variable for the magnitude earnings management, the empirical findings reveal that the ODACA of whole sample firms are significantly greater in contraction period than in expansion period. The results are also founded in food industry and plastic-chemical industry. 3) When using the absolute value of changes of operating discretionary accruals adjusted by net sales and growth rate (ODACS) as a proxy variable for the magnitude of earnings management, the empirical evidence indicates that the ODACS of all sample firms are significantly greater in contraction period than in expansion period. The evidence is also founded in food industry and plastic-chemical industry. 4) When using the absolute value of changes of non-operating income adjusted by total assets (NOI) as a proxy variable for the magnitude of earnings management, the empirical findings indicates that the NOI of all sample firms are significantly greater in contraction period than in expansion period. The results are also founded in electronic industry, electrical industry and construction industry.
Key Words : earnings management, operating performance, business cycle
