| 摘 要： | 借鉴经济合作与发展组织（OECD）的绿色专利识别方法，本文建构了2007—2017年中国城市尺度的绿色专利申请量时空数据库，从而揭示了2007—2017年中国绿色技术创新活动的时空分布特征，并基于空间杜宾模型探讨了其影响因素。研究发现：① 时序发展上，无论是在专利申请量上还是城市参与度上，绿色建筑技术一直主导中国绿色技术创新发展，11年间绿色建筑技术领域专利申请量占整体的比例一直维持在30%以上；② 创新主体上，中国绿色技术创新由企业主导的特征愈发显著，企业申请的绿色专利占整体的比例由2007年的39.7%增长至2017年的62.6%；③ 空间演化上，中国绿色技术创新空间分布呈现出显著的空间集聚性特征，以长三角、珠三角和京津地区为主导的三极格局日益凸显。个体城市上，11年间北京、深圳相继超越上海，成为中国绿色技术创新最为集聚的两大核心城市；④ 影响因素上，中国城市绿色技术创新具有显著的空间溢出效应和路径依赖性特征，城市环境规制强度、城市经济规模、城市市场规模、城市技术创新水平、城市吸引的FDI以及城市空气质量对城市绿色技术创新具有明显的积极影响，而以第二产业为主的产业结构对城市绿色技术创新具有明显的抑制作用。

| Abstract: | Green technology innovation is the first driving force to promote green development and harmonious coexistence between human and nature. Green technology innovation is the core issue of environmental economics, innovation economics, innovation management and other research fields. It is also one of the emerging topics in the field of environmental economic geography in recent years. Overall, the research on enterprise level is dominant, while the research on spatial scale is relatively less. In this paper, by deriving green patent applications for measuring green technology innovation from the Wanfang Patent Database, the spatial and temporal characteristics and its determinants of green technology innovation in China's city system from 2007 to 2017 are explored. The results indicate that technologies related to buildings has dominated the development of environmental innovation in China's city system, while technologies in the field of greenhouse gases and water adaptation were quite unpopular throughout China. In 2007, China's environmental innovation was dominated by individuals and enterprises. By 2017, enterprises have become the main body of China's environmental innovation, highlighting the essential characteristics of enterprises as the subject of environmental innovation. In space, the geography of environmental innovation in China's city system presents a strong spatial imbalance feature, a tripolar pattern dominated by the Yangtze River Delta, the Pearl River Delta, and the Beijing-Tianjin region has become increasingly prominent. In terms of determinants, spatial Durbin model regression results reflect that there are significant spatial spillover effects and path dependence characteristics in China's environmental innovation. Environmental regulation intensity, city size, market size, technological innovation level, FDI, and air quality have obvious positive effects on urban environmental innovation, while the industrial structure dominated by secondary industry has obvious inhibitory effect on urban environmental innovation. |
