As a typical example of an innovative governance environment, innovative city has become the focus of political and academic circles. Discussing the green innovation effect of this policy is beneficial in providing decision support for enhancing urban green innovation capability and solving the dilemma of urban resources. Based on data from 241 cities in China from 2005 to 2017, this paper takes innovative city construction as a "quasi-natural experiment" and uses the difference-in-differences method to empirically study the impact of China's innovative city construction on urban green innovation. The results show that innovative urban construction: has a positive effect on improving urban green innovation, and that this effect will gradually increase with time; promotes urban green innovation by expanding the scope of technology application, improving the efficiency of resource allocation and promoting the adjustment of industrial structure; and presents heterogeneity in cities' location, size and hierarchy. Finally, this paper proposes that the government should promote innovative policies in an orderly manner on the basis of following the principle of adapting measures to local conditions, as well as incorporating green innovation performance into the evaluation system for innovative city construction.
作为创新治理环境的典型范例，创新城市已成为政治和学术界关注的焦点。探讨该政策的绿色创新效应有助于为提高城市绿色创新能力和解决城市资源困境提供决策支持。本文基于 2005 年至 2017 年中国 241 个城市的数据，将创新城市建设视为一项“准自然实验”，采用双重差分法实证研究了中国创新城市建设对城市绿色创新的影响。结果表明，创新城市建设：对提高城市绿色创新水平具有积极作用，且这种效应会随时间推移逐渐增强；通过扩大技术应用范围、提高资源配置效率和促进产业结构调整来推动城市绿色创新；在城市位置、规模和层级上呈现异质性。最后，本文提出政府应在遵循因地制宜原则的基础上有序推进创新政策，并将绿色创新绩效纳入创新城市建设评价体系。
