Abstract: Technology-based enterprises have become a key carrier of China’s innovation-driven development strategy, and improving their green innovation capabilities is an important pathway toward achieving the “dual carbon” goals and advancing innovation-driven development. Spatially, technology-based enterprises have increasingly clustered into diversified and coordinated high-tech industrial agglomerations, providing new directions and impetus for achieving green innovation-oriented transformation. Using data from high-tech industrial zones and enterprise-level data of technology-based enterprises from 2011 to 2018, this paper empirically examines the impact and mechanisms of high-tech industrial agglomeration on corporate green technology innovation from the perspectives of substantive innovation and strategic innovation. The results show that high-tech industrial agglomeration significantly improves both substantive and strategic innovation, and the findings remain robust across a series of robustness checks. Comparatively, the effect on substantive innovation is more pronounced. High-tech industrial agglomeration promotes green innovation outcomes by increasing the research and development personnel and research and development expenditure in enterprises, thereby facilitating both substantive and strategic innovation. Government intervention not only has a negative impact on corporate green technology innovation, but also weakens the innovation effect of high-tech industry agglomeration, which has a restraining effect on corporate green technology innovation. Heterogeneity analysis shows that the positive effects of high-tech industrial agglomeration on green innovation are stronger in eastern regions, capital-intensive industries, and non-state-owned enterprises. This paper deepens the understanding of micro-level mechanisms through which high-tech industrial agglomeration promotes corporate green innovation and provides theoretical reference for the precise formulation of regional high-tech industrial development strategies and green innovation policies.

摘要： 技术企业已成为我国实施创新驱动发展战略的重要载体，提高其绿色创新能力是实现“双碳”目标与创新驱动的重要途径。目前，技术企业在空间上已形成多元化、协调发展的高新技术产业集聚区，为绿色创新转型提供了新方向与新动力。基于2011~2018年高新技术产业区数据与技术企业微观数据，本文从实质创新与策略创新的视角，实证检验了高新技术产业集聚对企业绿色技术创新的影响及其作用机制。研究发现：高新技术产业集聚能有效提升技术企业的实质创新与策略创新水平，该结论经过稳健性检验后依然成立；相对而言，产业集聚对企业实质创新的促进效应更为明显。机制分析表明，高新技术产业集聚通过增加企业的科研人员和科研经费投入，从而推动实质创新与策略创新产出。政府干预不仅会抑制企业绿色技术创新，还会削弱高新技术产业集聚的创新效应，对企业绿色技术创新产生负面影响。异质性分析显示，高新技术产业集聚对东部地区、资本密集型企业及非国有企业的绿色创新效应更为显著。本研究从企业微观层面深化了对高新技术产业集聚促进企业绿色创新内在机制的理解，为精准制定区域高新技术产业发展战略与绿色创新政策提供了理论依据。
