[目的]绿色创新是应对环境挑战并实现高质量发展的关键动力,研究新能源示范城市政策对绿色创新的影响及其作用机制,可为新能源示范城市政策的评估和优化改进提供基于企业层面的理论支持和经验证据.[方法]本文采用基尼系数、泰尔指数和空间马尔科夫链方法,揭示了2008-2020年间中国新能源企业绿色创新的平衡发展和时空转移特征.同时,采用双重差分模型评估了新能源示范城市政策对绿色创新的影响及其作用机制.[结果]①在研究期内,中国新能源企业的绿色创新分化程度逐渐扩大,呈现出"马太效应"现象.②新能源示范城市政策显著增强了新能源企业的绿色创新.具体而言,相比未实施新能源示范城市政策的城市,实施该政策的城市的新能源企业绿色创新显著提升了14%,这一结果经过了一系列稳健性检验的验证.③新能源示范城市政策通过增加研发投入和强化环境规制两个传导渠道来促进绿色创新.④异质性分析结果显示,新能源示范城市政策对于企业规模较小、融资约束较低的新能源企业的绿色创新影响更加显著.[结论]实施新能源示范城市政策对促进新能源企业的绿色创新具有积极影响.研究结果为政府推广新能源示范城市政策以及提升新能源企业的绿色创新提供政策参考.
[Objective]Green innovation is a key driving force for addressing environmental challenges and achieving high-quality development.Studying the impact and mechanism of policies for new energy demonstration cities on green innovation can provide theoretical support and empirical evidence at the enterprise level for the evaluation and optimization of policies in new energy demonstration cities.[Methods]Using the Gini coefficient,Theil index,and spatial Markov chain method,this study revealed the balanced development and spatial-temporal shift characteristics of green innovation in Chinese new energy enterprises from 2008 to 2020.A difference-in-differences model was employed to assess the effects and mechanisms of new energy demonstration city policies on green innovation.[Results](1)In the research period,inequality in green innovation among Chinese new energy enterprises in the new energy industry gradually increased over time,exhibiting a"Matthew effect".(2)New energy demonstration city policies significantly enhanced the green innovation of new energy enterprises.Specifically,compared to areas without the implementation of such policies,the green innovation of listed companies in cities with these policies increased by 14%,as supported by a series of robustness tests.(3)The policies achieved the enhancement in green innovation by boosting research and development investments and strengthening environmental regulations.(4)Heterogeneity analysis showed that the impact of new energy demonstration city policies on green innovation was more pronounced for companies with smaller scales and tighter financing constraints.[Conclusion]The implementation of new energy demonstration city policies has a positive influence on promoting green innovation in the new energy industry.The research results provide policy references for the government to promote new energy demonstration city policies and enhance the green innovation of new energy enterprises.
