创新驱动、能源转型与城市绿色创新生态建设

Innovation Drive, Energy Transition and Urban Green Innovation Ecological Construction

摘要:

在全球环境挑战日益加剧背景下,推动城市绿色创新与可持续发展已成为中国高质量发展的关键议题。以创新型城市与新能源示范城市“双试点”政策为研究对象,运用双重差分(difference-in-difference, DID) 模型,从协同治理视角系统考察技术创新与能源转型互动对城市绿色创新生态系统建设的影响机制。 研究结果表明,“ 双试点” 政策对城市绿色创新能力具有显著提升作用,并具有持续性正向效应。其作用机制主要体现在三方面:一是通过强化公众环境意识,扩大绿色技术的市场需求;二是有助于激发企业创新活力与人才创造潜能,优化创新要素配置;三是推动产业结构高级化,促进绿色经济内生增长。区域异质性分析显示,政策效应在东部地区、非资源型城市及知识传播能力较强的城市中更为显著。空间计量结果进一步揭示,“双试点”政策虽有效提升试点城市的绿色创新效率,但也可能导致非试点城市技术与资源外溢不足,形成区域发展的“虹吸效应”。研究结论有助于突破传统单一政策效应评估的分析范式,揭示技术创新与能源转型协同治理的倍增效应机制,不仅为协同治理与绿色创新理论提供新的实证支持,也为全球可持续发展政策如何在效率提升与区域公平之间实现平衡提供相应实践启示。

Abstract:

Against the backdrop of intensifying global environmental challenges, the fostering of green innovation and sustainable development in cities is considered pivotal to China’s high-quality development. The dual pilot policy of Innovative Cities and New Energy Demonstration Cities was investigated. A difference-in-differences model was applied from a collaborative governance perspective. The interplay between technological innovation and energy transition was analyzed to understand its role in urban green innovation ecological construction. The dual pilot policy is found to significantly and persistently enhance urban green innovation capacity. This effect is observed to operate through three key mechanisms. Firstly, public environmental awareness is raised, which expands market demand for green technologies. Secondly, corporate innovation is stimulated and talent potential is unleashed, thereby optimizing the allocation of innovation resources. Thirdly, industrial upgrading is advanced to foster endogenous growth in the green economy. Regional heterogeneity analysis indicates that the policy??s effects are more pronounced in eastern regions, non-resource-based cities, and cities with strong knowledge-dissemination capacities. Furthermore, spatial econometric results reveal that while green innovation efficiency is effectively boosted in pilot cities, a “regional siphon effect” may also be created. Technology and resources are diverted away from non-pilot cities, which may potentially hinder their development. Conventional single-policy evaluations are moved beyond by uncovering the synergistic effects of integrating technological innovation with energy transition. New empirical evidence is provided for collaborative governance and green innovation theories. Valuable insights are also offered for global sustainable development policymaking, particularly in balancing efficiency gains with regional equity.
