当前，我国经济已由高速增长转向高质量发展阶段，如何协调经济发展与环境保护之间的关系对于在新发展理念下持续推进经济高质量发展至关重要。绿色技术创新融合了绿色发展理念与创新驱动战略，对于促进生态文明建设与经济绿色发展的协同互动、加快经济发展方式向绿色低碳转变、实现区域经济的高质量发展具有深远意义。一方面，结合经济高质量发展的指导思想与时代内涵，从经济发展结构优化、经济发展动力变革、经济发展效率提升、经济发展成果共享和生态资源环境改善五个方面构建经济高质量发展综合指标体系，利用熵权TOPSIS法测度区域经济高质量发展水平；另一方面，基于绿色创新视角，深入探讨绿色技术创新对经济高质量发展的具体影响效应，并运用2006-2020年省际面板数据，建立静态面板模型、动态面板模型和空间杜宾模型实证考察绿色技术创新对区域经济高质量发展的整体促进作用、非线性影响和空间溢出效应。

研究结果表明：（1）我国区域经济高质量发展水平整体上呈现稳步增长趋势，但存在明显的区域不均衡性，形成“东高、中平、西低”的发展态势，中部和西部地区的追赶效应逐渐显现，且各地区的经济高质量发展存在较强的空间依赖性和空间集聚特征。（2）绿色技术创新在整体上积极推进了区域经济高质量发展，且存在先抑制后促进的“U型”非线性影响，经济高质量发展表现出明显的路径依赖特征和累加效应。绿色技术创新通过提高资源配置效率、促进企业节能减排、扩大地区市场需求影响经济高质量发展。（3）整体来看，经济高质量发展在各区域之间存在显著的正向空间自相关，绿色技术创新对周边地区的经济高质量发展具有显著的正向空间溢出效应。东部和中部地区的绿色技术创新表现出正向空间溢出效应，而西部地区绿色技术创新的负向空间溢出效应则较为显著。为此，提出如下对策建议：持续提高绿色技术创新水平，充分发挥其对于生产效率提升、生态文明建设和经济高质量发展的重要推动作用；提升绿色技术创新主体的能动性和积极性，有效激发绿色技术创新的资源配置效应、节能减排效应和市场需求效应；完善地区之间的创新合作和技术共享机制，通过绿色技术创新的空间溢出效应提高整体区域的经济高质量发展水平。

At present, China's economy has shifted from the stage of high-speed growth to high-quality development, how to coordinate the relationship between economic development and environmental protection is crucial to continuously promote high-quality economic development. Green technology innovation integrates green development concept and innovation driven strategy, which is of great significance to promote the synergistic interaction between ecological civilization construction and green economic development, accelerate the transformation of economic development mode to green and low-carbon, realize the high-quality development of regional economy. On the one hand, combined with the guiding ideology and connotation of high-quality economic development, the comprehensive evaluation index system of high-quality economic development is constructed from five dimensions: optimization of economic development structure, change of economic development dynamics, improvement of economic development efficiency, sharing of economic development achievements, improvement of ecological resources and environment, and the entropy TOPSIS method is used to measure the level of regional high-quality economic development. On the other hand, on account of green innovation perspective, the specific impact effect of green technology innovation on high-quality economic development is explored. The static panel model, dynamic panel model and spatial Durbin model are established to empirically investigate the overall promotion effect, nonlinear impact, and spatial spillover effect of green technology innovation on regional high-quality economic development.

The research results show that: (1) China's high-quality economic development level shows a steady growth trend, but there is obvious regional imbalance, forming a development trend of "high in the east, flat in the middle and low in the west". The catching-up effect of the central and western regions gradually emerges, and there are strong spatial dependence and spatial agglomeration characteristics of each region's high-quality economic development. (2) Green technology innovation significantly promotes regional high-quality economic development, and it has a "U-shaped" non-linear influence of first inhibiting and then promoting. The high-quality economic development shows obvious path-dependent characteristics and cumulative effects. Green technology innovation influences high-quality economic development by improving resource allocation efficiency, promoting energy saving and emission reduction, and expanding regional market demand. (3) From an overall perspective, there is a significant positive spatial autocorrelation among regions in terms of high-quality economic development, and green technology innovation shows a significant positive spatial spillover effect on high-quality economic development. Green technology innovation in the eastern regions and central regions has a positive spatial spillover effect, while the negative spatial spillover effect in the western region is more significant. To this end, the following countermeasures are proposed: Continuously improve the level of green technology innovation and make the most of its important role in production efficiency improvement, ecological civilization construction and high-quality economic development. Mobilize the motivation and enthusiasm of green technology innovation subjects, effectively stimulate resource allocation effect, energy-saving and emission reduction effect, and market demand effect of green technology innovation. Improve the innovation cooperation and technology sharing mechanism between regions, enhance the overall regional high-quality economic development level through the spatial spillover effect of green technology innovation.
