Abstract

As industrial policy shifts toward innovation orientation, understanding its role in shaping high-quality innovation is both timely and essential. This paper evaluates the impact of China's “Made in China (2025)” (MIC2025) pilot policy on the innovation quality of robotics firms using a difference-in-differences approach. To overcome limitations of traditional patent indicators, we introduce an enhanced PageRank algorithm to measure high-value innovation through patent citation networks. Results show that the MIC2025 policy significantly improves innovation quality, particularly in midstream and downstream segments of the robotics value chain. Mechanism analysis reveals that targeted innovation subsidies, stronger intellectual property protection, enhanced technology diffusion, and talent agglomeration jointly contribute to this improvement. These findings highlight how targeted industrial policy can foster high-quality innovation and suggest that future policy design should align support with firm capabilities and value chain characteristics.
“中国制造(2025)”是否提高了机器人技术的创新质量?来自基于网页排名的专利网络的证据
随着产业政策向创新导向转变,理解其在塑造高质量创新中的作用既及时又必要。本文采用差异中的差异方法评估了中国“中国制造2025”(MIC2025)试点政策对机器人企业创新质量的影响。为了克服传统专利指标的局限性,我们引入了一种增强的PageRank算法,通过专利引用网络来衡量高价值创新。结果表明,MIC2025政策显著提高了创新质量,特别是在机器人价值链的中下游环节。机制分析表明,有针对性的创新补贴、更强的知识产权保护、更强的技术扩散和人才集聚共同促进了这种改善。这些发现强调了有针对性的产业政策如何能够促进高质量的创新,并建议未来的政策设计应使支持与企业能力和价值链特征保持一致。

期刊介绍: Economic Modelling fills a major gap in the economics literature, providing a single source of both theoretical and applied papers on economic modelling. The journal prime objective is to provide an international review of the state-of-the-art in economic modelling. Economic Modelling publishes the complete versions of many large-scale models of industrially advanced economies which have been developed for policy analysis. Examples are the Bank of England Model and the US Federal Reserve Board Model which had hitherto been unpublished. As individual models are revised and updated, the journal publishes subsequent papers dealing with these revisions, so keeping its readers as up to date as possible.
