摘要:

为了研究数字经济对高质量出口的影响及其作用机制,立足于数字经济“去边界性”的核心特征属性,从本土市场整合与创新范式重塑两条路径入手探讨数字经济影响高质量出口的理论逻辑,构建2010—2020年281个地级及以上城市面板数据集,采用双重机器学习模型实证检验了数字经济影响高质量出口的作用路径及其影响效果。研究认为,数字经济发展能够显著促进高质量出口,该促进作用主要通过本土市场整合与创新范式重塑来实现; 数字经济对高质量出口的正向影响在城市间存在非对称性,具体而言,对于地理优势不明显的内陆以及政策支持力度较弱的地区,数字经济对其出口质量提升的驱动作用更加明显,能够极大释放增量红利。研究表明,需加快提高数字技术原始创新能力,积极推进信息数据资源的流通共享,来培育中国出口贸易新优势; 持续推动国内市场的高效畅通和规模拓展,优化国内区域布局; 采用差别性政策针对不同地区引导贸易高质量发展。

Abstract:

In order to study the influence of digital economy on high-quality exports and its mechanism, based on the core characteristic attribute of “de-boundary” of digital economy, this study discusses the theoretical logic of digital economy affecting high-quality exports from two paths: local market integration and innovation paradigm reshaping. By constructing the panel data set of 281 prefecture-level cities and above from 2010 to 2020, and adopting thedouble machine learning model, this paper empirically tests the action path and effect of digital economy on high-quality exports. The research believes that the development of digital economy can significantly promote high-quality exports, and this promotion is mainly realized through the integration of local markets and the reshaping of innovation paradigms. The positive impact of digital economy on high-quality exports is asymmetric among cities. Specifically, for inland areas with no obvious geographical advantages and areas with weak policy support, the driving effect of digital economy on the improvement of export quality is more obvious, which can greatly release incremental dividends. The research shows that it is necessary to accelerate the improvement of the original innovation ability of digital technology and actively promote the circulation and sharing of information and data resources to cultivate new advantages of China’s export trade. And it is also essential to continue to promote the efficient smoothness and scale expansion of the domestic market, optimize the domestic regional layout, and adopt differentiated policies to guide the high-quality development of trade for different regions.
