国家级城市群规划能否促进城市绿色创新?

城市群作为创新要素资源主要集聚地,是加快绿色创新发展、推动中国式现代化的关键载体。基于2006-2021年中国284个城市面板数据,运用多期双重差分法考察国家级城市群规划对城市绿色创新的影响效应和作用机制。研究发现:国家级城市群建设显著促进了城市绿色创新,这一促进作用在东部城市、非资源依赖型城市、创新基础较好和市场化程度较高城市中更显著有效。国家级城市群主要通过市场一体化、产业协作化、政策协同化等渠道扩大市场潜力、加快要素流动、促进产业升级、优化空间功能分工、增强环境规制,进而促进城市绿色创新。并且,国家级城市群政策对经济发展水平相近城市的绿色创新产生辐射带动,对空间和地理邻近地区可能存在负向溢出效应。
