因為大陸上市公司於現金增資時，須符合證監會相關的財務績效規定，本論文根據Healy (1985)的模式計算淨應計項目，並根據Modified Jones Model (1991)中有關不受影響的估計期間及受影響的事件期概念，進行比較分析以推論大陸上市公司在現金增資前是否會進行盈餘管理，而在現金增資後是否會產生淨應計項目的降低及業績衰退現象。本研究樣本係選取在大陸深圳及上海交易所掛牌之上市公司，由於本研究對公司的財務資料需要從現金增資前三年、現金增資當年及現金增資後兩年為期共六年的時間（期間假設為-3,-2,-1,0,1,2），故選定於1996年至2000年間辦理現金增資的公司做為觀察的樣本，故實際的的樣本期間是從1993至今，總計共九年的時間。論文之實證結果如下：
（一）盈餘管理部份
1.現金增資前盈餘增加源自於操控流動資產的應計項目、營業外淨利，而以流動負債項目來提高盈餘的情形並不顯著。
2.公司於現金增資前後之稅後盈餘、來自營業活動之現金流量和流動應計項目變動方向相反或變動幅度較小。
3.但現金增資前之短期應計項目與現金增資後之盈餘並沒有顯著的負向關係。
（二）績效衡量部分
1.公司增資後之營業淨利變動數/期初總資產、每股營業收入變動數和資產週轉率變動數可發現上市公司於現金增資後的財務績效平均有明顯衰退的現象。
2.營業淨利變動數/前一年度銷貨收入，因以銷貨收入作為平減數使公司間變異過大，但整體來說現金增資後的營業淨利變動數仍會降低。
3.每股資本支出變動數結果並未發現如預期衰退的現象，故推論公司並不會因增資而改變長期生產設備添購政策 。
（三）各群組分析部分
1.在96年∼98年公司財務狀況較99年∼00年佳，較少使用盈餘管理的工具去提高盈餘，且現金增資後經營績效衰退情況較少發生。
2.在96年∼98年公司多以應收帳款、存貨來提高盈餘，99年∼00年公司則多利用短期投資來提高盈餘。
3.較有誘因盈餘管理的公司，現金增資前會有明顯從事盈餘管理的跡象，現金增資前後應計項目和營業外淨利亦有異常的變動，且現金增資後的績效將有較大的衰退情形。
4.依本研究設計屬（特許）的公司群組實證結果並不未如預期推論。 / This study examines two major issues, potential earnings management and changes in operating performance in the event of seasoned offerings among listed companies in China. This study collects nine years data staring from 1993. The empirical findings can be summarized as two parts in the followings. The first part explains the empirical findings with respect to earnings management. First, the earning management behaviors significantly relates to accruals resulting from current assets and non-operating gains rather than accruals from current liabilities. Second, the after-tax net income, cash flows from operating activities, and current items of accruals have significant negative relationship before and after the event of seasoned offerings. Third, the short-term accruals prior to the event of seasoned offerings do not have significant negative relationship with earnings subsequent to the event as predicted in the hypothesis. The second part of empirical findings relate to operating performance between before and after the event of seasoned offerings. The results show that the operating performance decrease subsequent to the event of seasoned offerings in all measures developed in this study. However, the event of seasoned offering does not significantly affect the decision capital expenditures.
