摘要
基于中国2012~2022年284个地级及以上城市面板数据,利用固定效应模型、调节效应模型和广义嵌套空间模型,研究新质生产力对绿色创新效率的影响及城镇化在这一过程中所发挥的调节作用.结果表明:(1)新质生产力能显著提升绿色创新效率,该结论在一系列稳健性检验后仍然成立.(2)新质生产力对绿色创新效率的促进作用在东部地区最为显著,中部地区次之,西部地区尚不明显.(3)城镇化在新质生产力提升绿色创新效率的过程中发挥着积极的调节作用.(4)新质生产力能够产生正向的空间溢出效应,有效提升邻近地区的绿色创新效率.因此,建议积极培育新质生产力,因地制宜优化创新环境,大力推进绿色城镇化进程,构建高效的区域合作机制,以充分激发新质生产力的潜能,加快经济社会绿色转型.
Based on panel data of 284 cities at or above the prefecture level in China from 2012 to 2022,this paper studied the impact of new quality productivity on green innovation efficiency and the moderating effect of urbanization in this process by using fixed effect model,moderating effect model and general nesting spatial model.It was found that:(1)New quality productivity was confirmed to significantly enhance green innovation efficiency,a conclusion that still held after a series of robustness tests.(2)The promoting effect of new quality productivity on green innovation efficiency was most significant in the eastern region,followed by the central region,while no significant impact was observed in the western region.(3)Urbanization played a positive moderating role in the process of new quality productivity promoting green innovation efficiency.(4)New quality productivity was shown to generate positive spatial spillover effect that effectively improved green innovation efficiency of neighboring regions.Therefore,it was recommended to actively cultivate new quality productivity,optimize the innovation environment according to regional characteristics,vigorously promote the green urbanization process,and establish efficient regional cooperation mechanism to fully unleash the potential of new quality productivity and accelerate the green transformation of the economy and society.
