采用状态空间模型以及脉冲响应函数和方差分解研究信息化与经济增长关系的动态变化,结果表明,在改革开放初期,由于生产率悖论,信息化对经济增长的贡献为负,随着信息技术的普及和发展,生产率悖论消失。信息化对经济增长的贡献总体上小于劳动力和资本,而经济增长对信息化的带动作用比较显著。信息化的地位首先是作为一个产业存在的,其次才是对经济的带动作用,单纯信息化对经济增长的贡献可能被高估了。
This paper analyzes informatization and economy growth based on state space model and impulse response function. The results show that the contribution of informatization to economy growth is negative at the beginning of the reform and open policy. With the de- velopment of information technology, the Productivity Paradox of Informatization and economy growth has disappeared. The contribution of informatization to economy growth is smaller than capital and labor in general. The position of informatization first is an industry, sec- ond is the contribution to economy growth. The pure contribution of informatization to economy growth is highly overrated
