ERP与公司盈利绩效:来自沪深上市公司的经验证据

ERP and firm profitability:Empirical evidence from Chinese listed companies

通过收集沪深两市66家上市公司2-12年期大约340个样本观察值数据,使用广义最小二乘法在我国背景下实证研究了ERP与公司盈利绩效的关系.得出了以下两个结论:采用ERP后,短期而言(ERP采用后第1-5年),我国上市公司的盈利绩效(以ROA、ROE衡量)在统计上显著降低了;采用ERP后,短期而言,我国上市公司的盈利绩效(以ROA、ROE衡量)在统计上显著降低了,而在一个较长时期内,随着时间的推移,这种负面影响逐年减少,具有边际收益递增效应,表现出U型关系;长期而言,ERP采用对盈利绩效具有统计上显著的正面影响.

By using 66 Chinese listed companies data with 2-12 years period that consists of about 340 observations, this paper empirically study the relationship between ERP and asset management performance under Chinese context with GLS regression method.This study draws such two conclusions：Firstly,in the short term（i.e.after the lst-5th year since the adoption）,the adopttion of ERP has statistically significant negative impact on firm profitability;Secondly,in the short term,the adopttion of ERP has statistically significant negative impact on firm profitability;in a relative long term,as time goes by,such negative influence decreases gradually,and shows increasing marginal revenue effect and U shape relationship.In the long term,the adoption of ERP has statistically positive impact on firm profitability.
