摘要
基于2015年人工智能政策,探究其在提升企业盈利能力中的作用。以中小板和创业板上市企业作为研究样本,构建双重差分模型并进行准自然实验分析,识别人工智能政策的经济成效。结果表明,人工智能政策的实施初期在提升企业盈利能力方面存在一定局限性,但对东部地区和制造业企业的盈利能力提升较为明显。进一步研究发现,增加创新投入和缓解融资约束是人工智能政策提升企业盈利能力的机制。
Based on the artificial intelligence policy in 2015,the paper mainly explored the role of the policy in promoting enterprises'profitability.Taking SMEs and GEM listed enterprises as the example,the research firstly constructed the difference-in-differences approach to carry out the analysis of quasi-natural experiment,so as to identify the economic results of this policy.The results indicated that,at the early stage,there were certain limitations in the promoting effect of the policy,while the effect was more significant in the eastern region and in manufacturing enterprises.Further study revealed that,increasing innovation investment and alleviating financing constraints were two mechanisms through which the policy could enhance enterprises'profitability.
