The development of urbanization has brought new challenges to the ecological environment, and the promotion of green technology innovation and development is widely recognized as an essential method to achieve cities' economic benefits and environmental protection. This paper examines whether the new urbanization pilot policies (NUP) increase green technology innovation (GTI) from both theoretical and empirical perspectives. This paper examines the impact of new urbanization on GTI by analyzing data from 285 cities in China between 2010 and 2021, using the multi-period DID model with the implementation of NUP as an exogenous policy shock. The study results indicate that NUP significantly affects GTI, and the conclusion still holds after the parallel trend test, placebo test, and other robustness tests. Heterogeneity analysis shows that the NUP significantly enhances GTI in low environmental pollution, non-resource-based, Medium-sized, and Central Region cities. The test of moderating effect shows that NUP has a "linkage effect" with the government's environmental attention, financial investment in innovation, and regional talent pooling. The findings of this paper provide empirical evidence and decision-making reference for promoting NUP and sustainable development of cities.
城市化的发展给生态环境带来了新的挑战，而推动绿色技术创新和发展被广泛认为是实现城市经济效益和环境保护的必要方法。本文从理论和实证两个角度考察了新的城市化试点政策（NUP）是否增加了绿色技术创新（GTI）。本文通过分析 2010 年至 2021 年中国 285 个城市的数据，利用多期 DID 模型，以 NUP 的实施作为外生政策冲击，检验了新城市化对 GTI 的影响。研究结果表明，NUP 对 GTI 有显著影响，且在平行趋势检验、安慰剂检验和其他稳健性检验后，结论仍然成立。异质性分析表明，NUP 显著提高了环境污染程度低、非资源型、中等规模和中部地区城市的 GTI。调节效应检验表明，NUP 与政府的环境关注、创新财政投入和区域人才集聚之间存在“联动效应”。本文的研究结果为促进 NUP 和城市可持续发展提供了经验证据和决策参考。
