摘　　要：当今世界正在经历以数字经济为核心的第三次技术革命,数字经济的兴起创造了大量机遇,也带来了新的挑战。选取2005-2018年中国30个省份面板数据,以创新活动为中介变量,实证研究了数字经济对中国出口技术复杂度的影响。结果表明:数字经济显著提高了中国出口技术复杂度,这一结果在选取历史数据作为工具变量后依然成立,进一步通过空间杜宾模型发现数字经济对出口技术复杂度的影响存在显著的空间溢出且具有区域异质性。因而应加强数字经济基础设施建设,优化创新环境,促进区域协同发展,从而提升出口技术复杂度进而提高国际竞争力。The world today is experiencing the third technological revolution with the digital economy as its core.The rise of the digital economy has created many opportunities and brought new challenges.This paper selects panel data from 30 provinces in China from 2005 to 2018,and uses innovation activities as an intermediary variable to empirical study the impact of the digital economy on the complexity of China's export technology.The results show that the digital economy has significantly increased the complexity of China’s export technology.This result is still valid after selecting historical data as an instrumental variable.Further,through the spatial Dubin model,it finds that the impact of the digital economy on the complexity of export technology has significant spatial spillovers.Features and regional heterogeneity.Therefore,it is necessary to strengthen the construction of digital economy infrastructure,optimize the innovation environment,and promote regional coordinated development,to increase the complexity of export technology and improve international competitiveness.
