摘要
在资源环境与经济发展矛盾日益突出的背景下,绿色技术创新成为实现可持续发展与高质量发展的重要途径。文中基于2007—2021年中国上市公司微观数据,运用扩展CDM模型与多维面板固定效应模型,实证检验技术创新与绿色技术创新对企业全要素生产率的影响。研究发现,技术创新整体上促进企业全要素生产率,而绿色技术创新对污染企业存在“挤出效应”。异质性分析表明,企业规模较大、政府补贴较多、研发密集度较高、数字化转型程度较高,以及处于高竞争或高开放地区的污染企业,该挤出效应会减弱。进一步分析揭示地区知识存量对不同阶段创新活动的影响。研究为企业创新战略制定与政府推动绿色技术发展提供了科学参考。
Against the backdrop of increasingly severe contradictions between global resource and environmental constraints and economic development,green technological innovation has emerged as a critical pathway for achieving sustainable development and high-quality growth.Drawing on microdata from Chinese listed companies spanning 2007—2021,this study employs an extended CDM model and a multi-dimensional panel fixed-effects model to empirically examine the impact of both general technological innovation and green technological innovation on enterprise total factor productivity(TFP).The findings reveal that while technological innovation overall promotes enterprise TFP,green technological innovation exhibits a significant“crowding-out effect”on TFP within polluting enterprises.Heterogeneity analysis indicates that this crowding-out effect is mitigated for polluting firms that are larger in scale,receive more government subsidies,exhibit higher R&D intensity,possess a greater degree of digital transformation,or are located in regions characterized by high competition or a high level of openness.Further analysis elucidates the influence of regional knowledge stock on different stages of innovative activities.This research provides valuable empirical evidence and scientific reference for enterprises formulating innovation strategies and for governments aiming to promote the development of green technologies.
