互联网如何影响企业出口产品技术水平

How Does Internet Influence Export Product Technology Levels

在数字经济大发展背景下,互联网与国际贸易融合日渐紧密,企业外贸活动发生深刻变化。本文利用2004-2009年中国工业企业数据和海关数据,采用倾向得分匹配和双重差分法,实证检验了互联网应用对企业出口产品技术水平的影响及其机制。研究发现,互联网应用总体上促进了企业出口产品技术水平的提升;互联网应用的影响是其正反两方面共同作用的结果,对一般贸易出口企业主要表现为正向影响,对加工贸易出口企业则是负向影响。进一步异质性检验发现,互联网应用仅显著促进了中小企业、私营外资企业的出口产品技术水平的提升。
