城市群政策能否促进域内企业的合作创新?

摘要/Abstract

摘要： 在实施创新驱动发展战略和全国统一大市场建设背景下，本文实证检验了城市群政策对域内企业合作创新的影响。研究发现：①城市群政策显著提升了域内企业的合作创新水平，推动了技术要素的流动与整合；②该政策通过加大政府补助、强化知识产权保护、深化专业化分工三条路径发挥作用；③异质性分析显示，该效应在社会信任程度较低、产业集聚度较弱、市场竞争激烈的地区更为显著，对跨省份和多核心城市群的促进效应尤为突出，并显著提升了“企业-企业”“企业-高校”“企业-研究所”等多类型合作；④合作创新水平的提升进一步推动了企业全要素生产率增长。本文为在全国统一大市场建设进程中重塑企业创新模式提供了经验证据和政策启示。

Abstract: Against the backdrop of innovation-driven development strategy and the construction of a unified national market, this study empirically examines the impact of city clusters policies on inter-firm collaborative innovation. The findings reveal that: (1) city clusters policies significantly enhance collaborative innovation among enterprises within the same region by facilitating the flow and integration of technological factors; (2) the policies operate through three main channels—increasing government subsidies, strengthening intellectual property protection, and deepening specialization and industrial division of labor; (3) heterogeneity analysis indicates that the effect is more pronounced in regions with lower levels of social trust, weaker industrial agglomeration, and more intense market competition, with particularly strong impacts observed in cross-provincial and multi-core city clusters. These policies also significantly promote various types of collaboration, including “firm-firm,” “firm-university,” and “firm-research institute” partnerships; (4) the improvement in collaborative innovation further contributes to the growth of firms’ total factor productivity. This study provides empirical evidence and policy insights for reshaping enterprise innovation models amid the advancement of China’s unified national market.
