摘要
数字经济重构城市区位优势,为城市吸引资本等要素集聚提供新的助力,但与外商直接投资存在何种关系尚需进一步讨论。基于2005—2022年全国284个地级及以上城市面板数据,实证分析了数字经济发展对城市外商直接投资流入的影响与机制。研究发现,数字经济发展显著促进城市外商直接投资流入,这一促进作用在内生性检验和稳健性检验后仍然成立;市场规模扩张与城市创新质量提升是主要影响渠道,制度型开放安排如中欧班列开行与跨境电子商务综合试验区增强了数字经济对区域引资的促进作用。异质性研究发现,数字经济对外商直接投资的促进作用在内陆地区、非中心城市和再生型资源城市作用更大,体现了数字经济缩小区域开放发展鸿沟的普惠包容特质。以上研究结论,丰富了因地制宜发展新质生产力背景下数字经济的相关研究,进一步探究城市数字经济与制度型开放政策扩大高水平对外开放的协同机制,为新形势下加大引进外资力度提供新的战略思路。
The digital economy restructures urban location advantages,providing new impetus for cities to attract the aggrega-tion of capital and other factors.However,the relationship between the digital economy and foreign direct investment(FDI)re-mains to be further discussed.Empirically analyzing the impact and mechanisms of digital economy development on urban FDI inflows based on panel data from 284 prefecture-level and above cities across China from 2005 to 2022,the study finds that the development of the digital economy significantly promotes urban FDI inflows,which remains valid after endogeneity and ro-bustness tests.Market size expansion and urban innovation quality improvement are the main influencing channels,while insti-tutional openness arrangements such as the China-Europe Railway Express and cross-border e-commerce comprehensive pilot zones enhance the digital economy's role in promoting regional investment attraction.Heterogeneity analysis reveals that the digital economy's role in promoting FDI is greater in inland regions,non-central cities,and regenerative resource cities,re-flecting the inclusive characteristics of the digital economy in narrowing the regional development gap in openness.These re-search conclusions enrich the relevant research on the digital economy under the background of developing new-quality produc-tivity according to local conditions,further exploring the synergistic mechanism between urban digital economy and institution-al openness policies to expand high-level opening-up,and providing new strategic blueprint for attracting foreign investment underthenew situation.
