数字金融发展对出口技术复杂度的影响研究

Research on the Impact of Digital Finance Development on Complexity of Export Technology in China

数字金融作为传统金融与现代科技融合而成的新产物,不仅显著促进了企业全要素生产率的稳步提升,也促使了产业链与创新链的深度融合以及国家核心竞争力的持续增强,它正在成为重组全球要素资源、重塑全球经济结构、改变全球竞争格局的关键力量。文章将数字金融发展融入异质性企业贸易理论模型中,构建较为统一的理论分析框架,探讨数字金融发展影响出口技术复杂度的理论机理及其背后的作用机制,并通过构建计量回归模型进行实证检验。研究结果发现:第一,数字金融发展显著提高了出口技术复杂度,这个结论在一系列检验后仍然稳健;第二,数字金融发展不仅可以直接影响出口技术复杂度,而且还能通过知识获取、技术创新、制度改进、产业升级等作用机制间接影响出口技术复杂度;第三,数字金融发展对出口技术复杂度的影响存在非常显著的非线性特征和空间溢出效应;第四,在数字金融发展促进出口技术复杂度过程中,金融监管发挥着显著的调节效应。文章的研究结论可以为加快数字技术与实体经济深度融合,促进中国数字金融发展优化,加快外贸转型升级并推进贸易高质量发展提供经验证据和政策启示。

As a new product of the integration of traditional finance and modern science and technology,digital finance has significantly promoted the steady improvement of enterprise total factor productivity,the deep integration of industrial chain and innovation chain and the continuous enhancement of national core competitiveness.It is becoming a key force in restructuring global factor resources,reshaping global economic structure and changing global competition pattern.This paper integrates the development of digital finance into the trade theoretical model of heterogeneous enterprises,constructs a relatively unified theoretical analysis framework,discusses the theoretical mechanism and the underlying mechanism of the impact of digital finance development on export technology complexity,and makes an empirical test by constructing an econometric regression model.The results show that:first,the development of digital finance significantly improves the complexity of export technology,which is still robust after a series of tests;second,the development of digital finance can not only directly affect the complexity of export technology,but also indirectly affect the complexity of export technology through the mechanisms of knowledge acquisition,technological innovation,system improvement and industrial upgrading;third,the impact of digital finance development on the complexity of export technology has very significant nonlinear characteristics and spatial spillover effect;finally,in the process of digital finance development which promotes the complexity of export technology,financial supervision plays a significant regulatory effect.The research conclusion of this paper can provide reliable empirical evidence and policy enlightenment for accelerating the deep integration of digital technology and real economy,promoting the development and optimization of China’s digital finance,accelerating the transformation and upgrading of foreign trade and promoting the high-quality development of trade.
