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:

在全球环境挑战加剧的背景下，城市绿色创新可持续发展备受关注。本研究聚焦创新型城市与新能源示范城市的双试点政策，运用双重差分法揭示技术创新与能源转型协同治理对绿色创新生态系统的影响机制。研究发现，双试点政策显著提升城市绿色创新能力且具有持续效应，其作用机制体现在三个维度——增强公众环保意识以扩大绿色技术市场需求，激活企业与人才创新要素活力，促进产业结构高级化。政策效果呈现显著区域异质性，在东部地区、非资源型城市及知识传播能力强的城市尤为突出。通过空间计量发现，双试点政策虽有效提升试点城市绿色创新效率，但可能引发非试点城市的技术与资源流失，形成区域发展的“虹吸效应”。这表明当前政策在促进局部绿色转型的同时，需警惕区域发展失衡风险。研究突破传统单一政策评估范式，揭示协同治理策略通过要素整合产生的倍增效应。研究不仅为协同治理理论提供新证据，更为全球可持续发展政策制定中如何兼顾效率与公平提供实践参照。

Abstract:

Amid intensifying global environmental challenges, urban green innovation and sustainable development have garnered significant attention. This study examines the dual pilot policy integrating innovative cities and new energy demonstration cities, employing a difference-in-differences (DID) approach to uncover the mechanisms through which the synergistic governance of technological innovation and energy transition shapes green innovation ecosystems. The findings reveal that the dual pilot policy significantly enhances urban green innovation capabilities with sustained effects, operating through three key pathways: amplifying public environmental awareness to expand market demand for green technologies, stimulating the innovative potential of enterprises and talent, and promoting industrial structure upgrading. Policy effectiveness exhibits pronounced regional heterogeneity, with stronger impacts observed in eastern regions, non-resource-dependent cities, and cities with robust knowledge dissemination capacities. Spatial econometric analysis further identifies a "siphon effect," wherein the policy improves green innovation efficiency in pilot cities but risks exacerbating technology and resource drain in non-pilot areas, highlighting potential regional development imbalances. By transcending conventional single-policy evaluation paradigms, this research demonstrates how synergistic governance generates multiplier effects through resource integration. These insights not only provide novel empirical evidence for collaborative governance theory but also offer practical guidance for designing global sustainability policies that balance efficiency and equity, emphasizing the need to reconcile localized green transitions with interregional resource allocation dynamics.
