摘要
现有研究对于信息技术如何促进经济增长尚无定论,本文利用企业层面数据来回答这一问题。研究发现,使用信息技术的企业增长速度更快,并且增长质量更高。我们使用不同的指标,使用新成立企业和匹配企业样本,使用工具变量方法缓解内生性问题,上述结果仍十分稳健,但在不同类型的企业间存在异质性。本文在理论上阐述了信息技术的增长效应,并进行实证检验,这对我国当前的新经济发展战略具有明确的政策含义。
Computer and information technology is considered to be one of the most powerful engines for modern growth, but empirical evidence is still in need. In this paper, we explore this question with firm-level data. Primarily, we found that firms adopting computer and information technology grows faster and with even higher quality. Furthermore, to address potential endogeneity, methods like using alternative indexes, using newly-established firms and matched sample, and using instrumental variable are employed. Despite the heterogeneity among types of firms, the results are quite robust. Here, not only theoretical effect of computer and information technology on growth is explained, but also empirical tests for the theory are done, thus providing specific policy implications for the new economic development strategy in China.
