摘要
本文检验了证券市场监管规定是否影响了我国上市公司2001年自发性会计程序变更。研究表明通过自发性会计程序变更规避和迎合证券市场监管规定是上市公司的长期目标，强制性会计政策的变化使得不同时期自发性会计程序变更呈现不同的特征。因新企业会计制度的执行，2001年发生自发性会计程序变更的上市公司整体盈利水平下降，高盈利企业为了平滑盈余、大亏且当年无需扭亏的企业为借新会计制度执行之际进行“大清洗”而调减利润；高管人员变更也诱发了业绩差的上市公司进行调减利润的自发性会计程序变更。调增利润公司的主要目的是为了扭亏。本文研究还证明了Fields（2001）的研究结论：不同环境下有不同的会计程序选择模式。
This study examines whether the capital market supervision affects voluntary accounting procedure changes of the listed company. Starting with a sample of firms who voluntarily changed accounting procedures in 2001, we investigate whether the likelihood that the change in accounting procedure decreased （rather than increased） the finn＇s income depends on （1） whether the change in accounting procedure affects the firm to take a big bath and smoothing incotne, （2） whether the firm will be profitable, （3） whether the change in mandatory accounting policy will take place in this year, we find that firms whose income allow accounting procedure changes to affect ROE decreasing are more likely to make income-decreasing rather than income-increasing changes. These results suggest that the Chinese capital market supervision made the changes in voluntary accounting procedure of listed companies, and verify the fundamental result posed by Fields （2001） that there are different accounting procedures under different circumstances.
