摘　要：

运用新新贸易理论构建数字经济与出口产品质量的分析框架，采用微观贸易数据实证考察数字经济对制造业企业出口产品质量的影响效应与作用机制，可以发现：第一，数字经济能显著提升制造业企业出口产品质量。这一结论在改变关键变量衡量指标、考虑内生性、改变回归样本以及考虑行业趋势改变等稳健性检验后依然成立。第二，数字经济对制造业企业出口质量提升的驱动作用在不同贸易方式上和对不同所有制企业均表现出一定的异质性。第三，生产效率是数字经济驱动制造业企业出口质量提升的可能机制，而质量生产能力这一机制的作用并不显著。因此，政府应该加快数字经济战略部署，加速数字技术和数字产品创新，不断推动制造业企业出口质量升级，打造中国制造国际竞争新优势。

Abstract Adopting the framework of analyzing digital economy and export product quality on the basis of the new-new trade theory, this paper empirically investigates the effect and mechanism of digital economy on the quality of export products of manufacturing enterprises by using the micro-level trade data. The main findings are as follows. First, digital economy can significantly promote the export quality upgrading of manufacturing enterprises. This conclusion remained robust after changing the key variable measurement, considering the endogeneity and the change of trade tendency, and changing the regression sample. Second, the driving effect of the digital economy on the export quality upgrading of manufacturing enterprises shows certain heterogeneity in different trade modes and enterprises of different ownerships. Third, the production efficiency is a possible mechanism for the digital economy to drive the export quality upgrading of manufacturing enterprises, while the product productivity is not a significant mechanism. Therefore, the government should accelerate the strategic deployment of digital economy and the innovation of digital technology and digital products, continuously promoting the export quality upgrading of manufacturing enterprises and creating new advantages of "Made in China" in international competitions.
