【摘要】：针对当前测量方法无法反映信息技术投资绩效的动态变化过程问题,提出了一种基于动态调整速度的局部调整模型。该模型假设调整速度并不是固定不变的,而是宏观经济变量(国家特征)的线性函数,分别建立了BC和BT生产函数下4个信息技术投资绩效测量模型。通过比较在有、无信息技术投资情况下经济绩效的变动情况测算信息技术投资绩效,并以中国为例检验了信息技术投资对经济增长的影响以及信息技术投资绩效变动趋势。结果表明:信息技术投资对中国经济增长的影响并不显著,但国家特征对调整速度具有显著的影响;当信息技术作为生产要素进入生产过程后,经济绩效明显增长,表明在BC和BT生产函数下中国不存在信息技术的"生产率悖论"现象。
[Abstract]:In view of the fact that the current measurement method can not reflect the dynamic process of information technology investment performance, a local adjustment model based on dynamic adjustment speed is proposed, which assumes that the adjustment speed is not fixed. It is a linear function of macroeconomic variables (national characteristics), and four information technology investment performance measurement models under BC and BT production functions are established respectively. Measurement of the change of economic performance in the absence of information technology investment performance measurement of information technology investment performance, Taking China as an example, the influence of IT investment on economic growth and the trend of IT investment performance change are tested. The results show that the impact of IT investment on China's economic growth is not significant. However, the national characteristics have a significant impact on the adjustment speed. When information technology enters the production process as a factor of production, the economic performance increases significantly, indicating that there is no "productivity paradox" of information technology in China under the BC and BT production functions.
