信息化、企业研发与全要素生产率的实证分析

An Empirical Analysis of Informatization,Enterprise R&D and Total Factor Productivity

自信息技术生产率悖论被提出以来,企业信息技术投入与生产率变化特点一直备受关注,也存在不同看法。现有一些文献研究了信息化、企业研发对全要素生产率的影响,但对其中作用机理和实证分析不足。以2013-2018年我国412家创业板上市公司为研究对象,考察信息化、企业研发与全要素生产率的关系,结果显示:信息化水平与企业研发正相关,信息化水平越高,对企业研发的促进作用越大;企业研发与全要素生产率正相关,研发投入越高,对全要素生产率的促进作用越大;企业信息化与全要素生产率正相关,信息化水平越高,对全要素生产率的促进作用越大;企业研发在信息化与全要素生产率之间起着部分中介效应。进一步检验表明,不同行业或地区的企业信息化对全要素生产率的促进作用存在差异。最后,提出注重推进企业信息化建设、充分发挥企业研发的中介效应、根据行业选择信息化策略等建议,以期为企业发展、政策制定及相关研究提供参考。

Since the information technology productivity paradox was put forward,the characteristics of enterprise information technology investment and productivity change have been concerned,and there are different views.Some existing literatures have studied the impact of informatization and enterprise R&D on TFP,but the mechanism and empirical analysis are insufficient.Taking 412 GEM listed companies in China from 2013 to 2018 as the research objects,the paper examines the relationship between informatization,enterprise R&D and total factor productivity.The results show that:The informatization level is positively correlated with enterprise R&D,the higher the informatization level is,the greater the promotion effect on Enterprise R&D;the enterprise R&D is positively correlated with total factor productivity,the higher the R&D investment is,the greater the promotion effect on total factor productivity;the enterprise informatization is positively correlated with total factor productivity,the higher the informatization level is,the greater the promotion effect on total factor productivity is;enterprise R&D plays a partial mediating role between informatization and total factor productivity.Further test shows that the promotion effect of enterprise informatization on TFP is different in different industries or regions.Finally,it puts forward some suggestions,such as focusing on promoting enterprise informatization construction,giving full play to the intermediary effect of enterprise R&D,and selecting informatization strategies according to the industry,so as to provide reference for enterprise development,policy formulation and related research.
