摘要
以向房地产业转型的上市公司为样本,用数据包络分析法(DEA)计算出公司业务转型前后的绩效稳定性指标,对转型前后的绩效均值进行比较分析。研究发现,大多数上市公司向房地产业转型过程中绩效都有一定程度的提高,但是转型的长期效果不如意;采用借壳转型方式的公司绩效提升显著,采用内部发展方式的公司转型效果最差;原行业与房地产业的相关程度并不能显著影响企业的转型绩效。
Taking as sample 25 listed companies which had a business transformation to real estate industry, this paper uses the DEA method to evaluate the stability index values for individual DMU on a year by year basis. The study reveals that most transformation can increase the performance in a short period, but the long-term effect is not satisfactory. It is confirmed that the promotion of performance with shell transition is notable, but the internal development has the least effect. The correlation degree between original industry of samples and real estate industry does not significantly affect the level of the performance of transformation.
