摘　　要：将国家数字经济创新发展试验区作为一项准自然实验,以2016—2021年A股上市公司为研究对象,采用双重差分法考察试验区设立的创新效应。结果表明:第一,试验区设立能促进企业创新,各试点政策的创新效应从大到小依次为:创新型城市建设、国家数字经济创新发展试验区、智慧城市创建、国家级大数据综合试验区、宽带中国示范城市;第二,试验区设立通过降低交易成本、集聚人才资源、促进知识产权保护、推动数字化转型,进而激励企业创新;第三,试验区设立对企业创新的促进作用在非国有企业、高新技术企业、在位企业中更显著,且相比于渐进式创新,试验区设立对突破式创新的影响更显著。此外,试验区设立对毗邻城市企业创新有正向扩散效应,对经济发展水平相似城市的企业创新有负向虹吸效应。In the era of digital economy,promoting the deep integration of digital technology and the real economy has become the key to achieving high-quality economic development.In this context,in October 2019,the National Development and Reform Commission and the Central Cyberspace Office jointly formulated and issued the Implementation Plan of the National Digital Economy Innovation and Development Pilot Zone(hereinafter referred to as the Plan),establishing Xiong'New Area;Zhejiang Province,Fujian Province,Sichuan Province,Guangdong Province,Chongqing City and other places as national digital economy innovation and development pilot zones(hereinafter referred to as the pilot zones).The pilot zones promote high-quality development,and keep improving the level of internationalization of the regional digital economy,thus playing a leading and radiating role.The digital economy is vital for enterprises to seek breakthroughs in independent innovation,and data has become an important factor in production in this era.However,the pilot zones directly drive the development of the digital economy,relevant research is still relatively lacking,and the impact path of the innovation effect needs to be clarified.To this end,this paper empirically examines the impact of the establishment of the pilot zone on enterprise innovation,which not only provides micro-level support for the policy dividend of the national digital economy innovation and development pilot zones,but also provides a basis and reference for promoting the construction of the pilot zones,empowering enterprise innovation,and helping to build"digital China".In order to accurately evaluate the impact of the pilot zone on enterprise innovation,this paper takes the National Digital Economy Innovation and Development Pilot Zones as a quasi-natural experiment with A-share listed companies from 2016 to 2021 as the research object,and employs the DID method to conduct research.It is found that(1)the establishment of the pilot zones can promote enterprise innovation,and the sup
