国家自主创新示范区政策与企业新质生产力培育——政策赋能、机制路径与异质性差异的微观解析

National Independent Innovation Demonstration Zones Policy and the Cultivation of Corporate New Quality Productivity: A Micro-Analysis of Policy Empowerment, Mechanism Paths, and Heterogeneous Differences

摘要:

在新发展格局下,以国家自主创新示范区为代表的创新驱动政策,能否真正成为创新驱动发展的“试验田”,进而赋能企业新质生产力的培育与发展? 本文基于2011—2022年我国沪深A股上市公司数据,探讨国家自主创新示范区政策与企业新质生产力的内在因果关系。研究发现:国家自主创新示范区的设立能够有效促进企业新质生产力的培育,此结论通过一系列稳健性检验后依然成立。进一步的机制分析表明,国家自主创新示范区可以通过推动企业数字化转型、提升企业实质性创新水平赋能企业新质生产力的培育;异质性分析表明,国家自主创新示范区的设立对企业新质生产力培育的积极作用因企业的产权性质、高新技术特征、规模、生产要素密集度以及战略区域的不同而呈现出显著差异。研究结果有助于深化对创新驱动政策和企业新质生产力的认识,并为我国企业新质生产力的培育提供了有效的经验证据。

Abstract:

Within the context of the new development pattern, it is examined whether innovation-driven policies, represented by National Independent Innovation Demonstration Zones (NIIDZs), can effectively function as “ testing grounds” for innovation-driven development and thereby facilitate the cultivation and enhancement of corporate new quality productive forces. Based on panel data from Shanghai and Shenzhen A-share listed companies in China between 2011 and 2022, the internal causal relationship between NIIDZ policies and corporate new quality productive forces was explored. It is found that the establishment of NIIDZs significantly promotes the development of corporate new quality productive forces, a conclusion that remains robust after a series of tests. Further mechanism analysis indicates that the establishment of NIIDZs empowers the cultivation of corporate new quality productive forces by advancing corporate digital transformation and enhancing the level of substantive innovation. Heterogeneity analysis reveals that the positive effect of NIIDZ establishment varies significantly across enterprises with different ownership structures, technological attributes, scales, factor intensities, and regional strategies. The findings are helpful for deepening the understanding of innovation-driven policies and corporate new quality productive forces, and provide effective empirical evidence for fostering new quality productive forces in Chinese enterprises.
