Increasing carbon productivity is an important measure taken by China to deal with global climate change, and technological innovation is the fundamental way to promote industrial carbon productivity. To explore the low-carbon effects of technological innovation, based on the panel data of 30 provinces in China from 2009 to 2017, this paper established a spatial panel measurement model and a panel threshold regression model to explore the spatial spillover effects and threshold characteristics of technological innovation on industrial carbon productivity. The research shows the following: on the one hand, technological innovation and industrial carbon productivity each has obvious spatial correlation, and technological innovation has a significant spatial spillover effect on the improvement of industrial carbon productivity, and the indirect spillover between regions is greater than the direct spillover effect within the area. On the other hand, the impact of technological innovation on industrial carbon productivity has a double threshold effect. With the continuous improvement of technological innovation capabilities, the promotion of industrial carbon productivity has become increasingly more influential. Through the division of threshold values, the technological innovation capabilities of various regions in China are significantly heterogeneous, and the overall level is low. Although technological innovation capabilities have improved in recent years, there is still much room for improvement. Finally, this article puts forward relevant suggestions from the construction of regional technological innovation system, economical green circular development, and the establishment of a green technological innovation system.
提高碳生产力是中国应对全球气候变化的重要举措，而技术创新是促进工业碳生产力提高的根本途径。为了探索技术创新的低碳效应，本文基于 2009-2017 年中国 30 个省份的面板数据，构建了空间面板计量模型和面板门槛回归模型，探讨了技术创新对工业碳生产力的空间溢出效应和门槛特征。研究结果表明：一方面，技术创新和工业碳生产力都具有明显的空间相关性，技术创新对工业碳生产力的提高具有显著的空间溢出效应，区域间的间接溢出大于区域内的直接溢出效应；另一方面，技术创新对工业碳生产力的影响具有双重门槛效应。随着技术创新能力的不断提高，对工业碳生产力的促进作用越来越大。通过划分门槛值，可以发现中国各地区的技术创新能力存在显著的异质性，整体水平较低。尽管近年来技术创新能力有所提高，但仍有很大的提升空间。最后，本文从区域技术创新体系建设、经济绿色循环发展、绿色技术创新体系建立等方面提出了相关建议。
