摘　　要：本文较为系统地考察了我国资本市场两类主要的会计估计变更伴随的盈余效应。基于2003-2011年间A股上市公司公告的应收账款坏账计提比率变更和固定资产折旧率变更数据,我们发现:第一,如果公司的会计估计水平(即坏账计提比率或折旧率)背离行业正常水平的幅度越大,公司越可能在下一期作出与行业水平趋同(而非背离)的估计变更;第二,与相对稳健的会计估计相比,相对激进的会计估计表现出显著更强的行业趋同效应。上述证据意味着,公司管理层进行会计估计的自主空间受到会计信息可验证性和企业经济基础的制约,从而在总体上趋于稳健而非更加激进。This study investigates the earnings effect associated with two major types of accounting estimate changes( i. e.,revision of the percentage allowance for doubtful accounts receivable and revision of the depreciation rate) made by Chinese listed firms during 2003-2011. We find that the more a firm's accounting estimate diverges from the industry-level estimate for the same category of assets,the more likely is the firm to change the estimate in convergence with( rather than deviating further from) the industry level in the following period. Moreover,the tendency to converge with the industry-level estimate is significantly stronger for previously aggressive estimates than for previously conservative estimates. These findings are consistent with the notion that management discretion in accounting estimates is restrained by the demand for verifiability of accounting information and the firm's underlying economic forces,thus overall decreasing the degree of earnings aggressiveness.
