根据2013—2017年制造业上市公司数据,本文在手工收集企业实施“互联网+”指标的基础上,实证检验了“互联网+”战略对企业研发投入的影响及其对不同企业的异质性作用。结果表明,“互联网+”战略对企业研发投入具有显著促进作用;这种促进作用只在东部地区显著,而在中、西部地区不显著;“互联网+”战略更能促进国有和民营企业进行研发投入,对外资企业研发投入存在抑制作用;生产率影响了“互联网+”战略与企业研发投入的关系,生产率较高的企业实施“互联网+”战略的创新效应更强。扩展检验发现,“互联网+”战略对企业研发投入的促进作用具有持续性,并且其影响程度逐年增强。研究结论为进一步实施“互联网+”战略以及制造业创新发展提供了微观层面的经验证据及决策支持。 |

Abstract: |
It used the data of manufacturing listed company in 2013—2017 to testify the impact and heterogeneous effect of the “Internet +” strategy on corporate R&D investment, based on manual collection of indicators reflecting the implementation of “Internet +” strategy. The results show that “Internet +” strategy has a significant positive effect on corporate R&D investment; this promotion effect is significant only in the eastern region, but not significant in the central and western regions; “Internet +” strategy can better promote the R&D investment of state-owned and private enterprises, and has a restraining effect on foreign companies; productivity affects the relationship between “Internet +” strategy and corporate R&D investment, and higher productivity companies have stronger innovation effects in implementing “Internet +” strategy. The extended inspection found that the promotion effect of “Internet +” strategy on corporate R&D investment is continuous and its influence has been increasing year by year. It provides micro-level empirical evidence and decision support for the further implementation of the “Internet +” strategy and the innovative development of manufacturing. |
