摘要
IT资源与企业绩效的正相关性是IT投资绩效研究领域的基石,然而近期的实证研究显示二者的相关性已经消失,探究其根源已经成为学术界的紧迫任务。本文认为,采用先进信息技术搭建的IT架构超越了传统的IT架构,依附传统IT架构的IT资源因此逐渐丧失盈利能力,直至对企业绩效的贡献消失。事实上,IT资源的开发需要耗时数年,IT资产的盈利能力在此期间随着IT资源的集聚逐渐上升,此后信息技术进步的作用才会凸现,导致IT资产的盈利能力回落,呈倒U型的变化趋势。本文以中国A股上市的1 221家稳定运行的公司为样本,从国泰安CSMAR数据库获取了样本公司2007年至2020年的样本数据,检验了这一推断。结果显示,IT资产的盈利能力在第3年攀升到峰值后逐渐回归到了社会平均水平,和上述推断吻合。IT投资绩效的研究大多以资源基础论为理论工具,强调IT资源的可持续性,本文证实了IT资源的盈利能力是3~5年的短暂存在,揭示了IT资源与企业绩效正相关性消失的根源。
The positive link between information technology resource and firm performance is held by many researchers and works as a cornerstone in their studies. However, it was reported that the correlation between them disappeared in empirical studies recently.It is urgent to explore the reason why the correlation disappeared.It is argued that the IT infrastructures built on advanced information technology outperform the one built on traditional technology, and IT resource related to traditional infrastructures decays gradually. As a result, the correlation between IT resource and firm performance disappeared.In fact, the development of IT resource takes several years, and the profitability of IT assets rises correspondingly during the time, then decline because of information technology progress, working as an inverted U curve after it tops out in two or three years.In order to test this hypothesis, we selected 1221 listed companies on Shanghai or Shenzhen Stock Exchanges as the sample, and obtained their financial data during 2007 to 2020 from the China Stock Market Accounting Research database(CSMAR).The empirical results showed that the profitability of IT assets rose until it toped out in the third year;and declined in the fourth, fifth and sixth years year until it was a tad above average again.Then the hypothesis, i.e.information technology progress devalue traditional IT resource, was confirmed.The researches on IT value were based on resource-based view which focused on IT resources' sustainability, while it was verified that the value of traditional IT resource can maintain three to five years only, as was the reason why the correlation between IT resource and firm performance disappeared.
