服务贸易创新与服务企业数字化转型研究

Research on ServiceTrade Innovation and Digital Transformation of Service Enterprise

以2008—2021年992家服务业上市公司数据为样本,利用多期DID及合成DID方法检验服务贸易创新试点政策对企业数字化转型的影响。研究发现:政策能有效地促进企业的数字化转型,对生产性服务企业作用明显,对消费和公共服务企业无显著作用;对非国有企业促进作用更大,且更有利于发展人工智能技术;更有利于数字基础设施建设发达地区的企业;政策可通过降低短期借款依赖度和综合税率的方式影响企业数字化转型。

Based on the data of 992 listed service companies from 2008 to 2021,this paper tests the influence of service trade innovation pilot policies on enterprises'digital transformation by using Time-varying DID and Synthetic DID methods.The results show that the policy can effectively promote the digital transformation of enterprises,which has a significant effect on productive service enterprises,but has no significant effect on the consumer and public service enterprises.The policy plays a greater role in promoting non-state-owned enterprises and has a significant positive ef-fect on the development of artificial intelligence technology.The policy is more conducive to the enterprises in areas with developed digital infrastructure construction.The policy affects enterprises'digital transformation by reducing short-term loan dependence and comprehensive tax rate.
