在当前不确定性增多的环境下,提升出口韧性能够帮助应对外部经济波动,进而促进经济稳定发展。因此,在当前复杂多变的国际贸易环境下,如何充分借助制度支撑和政策支持来有效彰显出口韧性,显得尤为关键且迫切。本文基于国家知识产权示范城市政策的准自然实验,利用中国海关数据库和工业企业数据库匹配数据,考察该政策对微观企业出口韧性的影响。研究结果表明:(1)国家知识产权示范城市政策的实施能显著增强示范城市企业的出口韧性,提升出口企业外部风险承担能力。(2)异质性研究发现,知识产权示范城市政策对企业出口韧性的提升效果在高盈利能力企业、非国有企业以及知识产权保护较完善地区更为明显。同时,本文以地级市为研究样本,将研究时间范围拓展至2009—2022年,发现知识产权示范城市政策对出口韧性的正向促进效应仍然存在。(3)机制检验结果表明,出口多元化拓展与出口技术复杂度提升是知识产权示范城市政策提高企业出口韧性的关键作用机制。本文丰富了国家知识产权示范城市政策和出口韧性之间的关系研究,完善了国家知识产权示范城市政策对企业出口韧性作用机理和影响效应的理解,为充分发挥国家知识产权示范城市在提升出口韧性方面的作用提供了重要的决策参考。

In the current environment where uncertainties are increasing, enhancing export resilience can help mitigate external economic fluctuations and thereby promote stable economic development. Therefore, in the complex and volatile international trade environment, how to fully leverage institutional support and policy backing to effectively enhance export resilience is particularly critical and urgent. This paper, based on a quasi-natural experiment of the national intellectual property demonstration cities policy, utilized the data matched from the China Customs Database and the Industrial Enterprises Database to examine the impact of this policy on the export resilience of local enterprises. The findings are as follows: (1) The implementation of the national intellectual property demonstration cities policy significantly enhances the export resilience of enterprises in the demonstration cities and improves their ability to bear external risks. (2) The heterogeneity analysis revealed that the policy's effect on enhancing export resilience is more pronounced in high-profitability enterprises, non-state-owned enterprises, and regions with well-established intellectual property protection. Additionally, using prefecture-level cities as research samples and extending the study period to 2009-2022, we found that the positive effect of the national intellectual property demonstration cities policy on export resilience still exists. (3) The mechanism analysis showed that the key mechanisms through which the policy enhances export resilience are diversification of exports and improvement in export technological complexity. This paper has enriched the research on the relationship between the national intellectual property demonstration cities policy and export resilience and improves the understanding of the mechanisms and effects of this policy on enterprise export resilience. It will also provide important policy references for fully leveraging the role of national intellectual property demonstration cities in enhancing export resilience.
