绿色技术创新、节能减排与成渝地区双城经济圈经济高质量发展

Green Technology Innovation,Energy Saving and Emission Reduction and High-quality Economic Development of Chengdu-Chongqing Economic Circle

成渝地区双城经济圈建设作为我国重要的战略增长极,迫切要求依托绿色技术创新加快经济高质量发展。基于2005—2020年成渝地区双城经济圈市级面板数据,运用动态面板系统GMM模型探究绿色技术创新对高质量发展的影响效应,并识别绿色创新的节能减排渠道作用。研究结果表明:绿色技术创新显著促进了成渝地区双城经济圈经济高质量发展;“节能效应”是绿色技术创新影响的有效路径,但“减排效应”存在明显的遮掩效应;因技术异质性和城市区位异质性,不同特征城市的绿色技术创新虽均存在显著的促进效应,但影响机制存在明显差异性。应加强绿色技术创新政策支持,推动绿色创新协同发展,加大绿色技术创新投入力度,完善产学研绿色创新合作机制,优化节能减排考评体系。

The Chengdu-Chongqing economic circle, as an important strategic growth pole in China, urgently requires relying on green technology innovation to accelerate high-quality economic development. This paper is based on the municipal-level panel data of the Chengdu-Chongqing economic circle from 2005 to 2020, explores the impact of green technology innovation on high-quality development using the dynamic panel system GMM model, and identifies the energy-saving and emission reduction channels of green innovation. The results show that: green technology innovation significantly contributes to the high-quality economic development of the Chengdu-Chongqing economic circle;the “energy saving effect” is an effective path for the impact of green technology innovation, but the “emission reduction effect” has an obvious masking effect;according to technology heterogeneity and city location heterogeneity, there is a significant promotion effect of green technology innovation in different characteristic cities, but there are obvious differences in the influencing mechanisms. To further accelerate the high-quality development of the Chengdu-Chongqing economic circle, we should strengthen policy support for green technology innovation, promote the coordinated development of green innovation, increase investment in green technology innovation, improve the mechanism of industry-university-research green innovation cooperation, and optimize the evaluation system for energy saving and emission reduction.
