根據Basu (1997)對會計保守性的定義：公司認列壞消息的速度會比認列好消息快，本文採用1999到2012年台灣上市、上櫃公司為研究樣本，並以C-SCORE (Khan and Watts, 2009) 作為衡量會計保守之方式，探討總統選舉所帶來的政治不確定對會計保守性的影響。研究結果顯示，在總統選舉前企業會調高會計報表的保守程度，也就是採取更積極的態度認列費用與損失。再者，本文也發現，選舉競爭程度越高以及現任總統試圖尋求連任等因素，會造成選舉的結果更難預測亦或是對於現有政策是否得以延續的不確性更高，進而導致會計保守性增加。

Under Basu’s (1997) interpretation of conservatism, earning reflects bad news more quickly than good news. My samples include observations of firm listed on Taiwan stock exchange market and over-the-counter (OTC) market from 1999 to 2012, and I employ the C-SCORE measure to examine the variation of accounting conservatism around Taiwan presidential elections. My empirical result shows that accounting conservatism increase in the years prior to the election periods. Further, I also find that the effect of political uncertainty on accounting conservatism is greater when election is more competitive or incumbent president is seeking re-election.
