現金是企業流動性最強的一項資產，良好的現金流循環對於企業日常的經營、籌資、投資活動起著重要的作用。本文以2009-2016年中國主板、中小板及創業板上市企業為研究對象，對這三個市場上市企業的現金持有水平及其影響因素進行比較分析。 本文在Opler等(1999)現金持有影響因素模型的基礎上，參考學者對中國大陸上市企業現金持有影響因素的選擇，結合公司治理、行業及宏觀因素，建構了現金持有的影響因素檢驗模型，通過實證研究主要得出了以下結論：1、中小板及創業板市場上市企業現金持有水平均高於主板市場；2、中小板及創業板市場上市企業現金持有水平的構成與主板市場存在顯著差異；3、現金持有水平存在行業差異；4、主板市場及創業板市場“經濟新常態”前後期現金持有水平存在顯著差異；5、股權結構，即管理層持股水平和國有持股水平對現金持有水平在主板市場上呈顯著正相關關係。 本文的研究，從學術的角度看，為企業現金持有水平的影響因素的研究提供了新的切入點，以中國大陸主板、中小板及創業板上市企業作為研究對象，探究三個市場上市企業現金持有水平及其影響因素的差異。從實務的角度看，通過本文的研究，可以明確不同市場現金持有水平及其影響因素的差異，為企業現金管理決策提供新的思路。 / Cash is the most liquid current accent in balance sheets.
