本研究探討台灣化學生技醫療產業上市櫃公司利用研發支出進行盈餘管理之行為,檢視化學生技醫療產業公司在虧損上市與上市後首度產生虧損的情況下,是否有顯著降低研發支出的情形,並研究降低研發支出在不同情況下,對公司後續年度營運績效所帶來之影響。研究結果顯示,化學生技醫療產業公司在虧損上市後二年內或上市後首度產生虧損之二年內,均有顯著降低研發支出的情形。意謂著化學生技醫療產業公司在上述兩種情況下均面臨報導正盈餘的壓力,而有利用研發支出進行盈餘管理之情形。本研究結果亦發現,同樣在降低研發支出的情況下,過去年度研發支出低的化學生技醫療產業公司,其後續二年度營運績效較差。此結果凸顯出研發支出對化學生技醫療產業公司的重要性,若公司過去研發投入程度低,當其後續再降低研發支出時,會對後續四年之營運績效皆帶來負面影響;反之,如果公司過去研發投入程度高,較能避免降低研發支出對未來營運績效所造成之負面影響。過去研究(Chan, Martin, and Kensinger, 1990; Roychowdhury, 2006; Osma and Young, 2009)多認為降低研發支出對公司後續年度營運績效有負面影響,但卻未區分出過去年度研發支出高或低之狀況,本研究補足了過去實證文獻之不足。
This study examines the behavior of Taiwan’s chemical, biotechnology, and medical care industry companies (listed and over the counter) in the use of R&D expenditure for earnings management. We examines whether there is a significant reduction in R&D expenditure in the case of chemical, biotechnology, and medical care Industry companies in the event of loss listed and listed losses for the first time. We also examine the reduction of R&D expenditure in different circumstances, the company's following annual operating performance effect. The result shows that chemical, biotechnology, and medical care industry companies have significantly reduced R&D spending within two years after the loss listed or within two years of the first loss after listing. This means that the chemical, biotechnology, and medical care industry are faced with the pressure of reporting positive earnings in the two cases, and the situation of using R&D expenditure for earnings management. The result of the study also finds that the same in the case of reducing R&D expenditure, the companies that have low past years’ R&D expenditure would have the worse operating performance on the subsequent second years. The result underscores the importance of R&D spending to chemical, biotechnology, and medical care industry companies. If the company's R&D investment is low in the past, it will have a negative impact on the subsequent four years’ operating performance when it reduces R&D expenditure again. If the company's past R&D investment is high, it could avoid the negative impact of reducing R&D spending on future operations. Prior researches (Chan, Martin, and Kensinger, 1990; Roychowdhury, 2006; Osma and Young, 2009) suggested that the reduction of R&D expenditure had a negative impact on the subsequent annual
operating performance of the company, but they did not distinguish the high or low R&D expenditure in the past years. This study complements the lack of previous empirical literature.
