摘　　要：以绿色专利转让刻画绿色技术扩散,分析了2001—2020年中国城市绿色技术扩散的时续动态以及空间格局,揭示了中国城市绿色技术扩散活动中的热门技术、行为主体和城市类型,并探讨了驱动中国城际绿色技术扩散的主要因素。研究发现:(1)中国绿色技术交易市场中的热门技术由环境治理技术快速转变为绿色建筑技术和清洁能源技术,企业始终是绿色技术扩散的主要行为体;(2)绿色技术跨城流动成为新常态,城市角色逐渐由自给自足式的城内集散型向开放创新式的城际集散型发展,全国统一的绿色技术交易大市场正在逐渐形成;(3)绿色技术扩散活动高度集聚在由东部沿海和长江经济带组成的“T”型地区,其中城际绿色技术扩散形成以京津、长三角、珠三角、成渝地区为枢纽的菱形网络;(4)遵循偏好连接和同配性法则,城际绿色技术扩散网络中新加入城市倾向于从枢纽城市获取绿色技术,但枢纽城市间的绿色技术流动更加频繁;(5)多维邻近性分析框架下的模型回归结果揭示了城市间技术差距、地理邻近性、经济邻近性、认知邻近性对城际绿色技术扩散的形成机制差异。Building a market-oriented green technology innovation system to accelerate the diffusion of green technology between regions,cities,and institutions has become a national strategy.Using green patent transfer to characterize the diffusion of green technology,this paper analyzed the temporal development dynamics and spatial distribution pattern of green technology diffusion in China from 2001 to 2020,and also discussed the main factors driving the diffusion of green technologies in Chinese cities.The study found that from 2001 to 2020,the popular technologies in China's green technology market rapidly changed from environmental governance technology to green building technology and clean energy technology,while enterprises were always the main actors of green technology diffusion.Secondly,from 2001 to 2020,with the cross-city flow of green technology becoming the new normal,a unified national green technology trading market was gradually taking shape.Thirdly,green technology diffusion activities were highly concentrated in the"T"region composed of the eastern coastal areas and the Yangtze River Economic Belt,in which the intercity green technology diffusion formed a diamond network with the Beijing-Tianjin,Yangtze River Delta,Pearl River Delta and Chengdu-Chongqing regions as the hubs.Fourthly,following the principle of preference connection and the law of assortativity,new cities in the intercity green technology diffusion network tended to obtain green technology from hub cities,but the flow of green technology between hub cities was more frequent.Fifthly,the regression results of the model under the multi-dimensional proximity analysis framework also verified the above laws,and revealed the differences in the formation mechanism of intercity green technology diffusion caused by technology gap,geographical proximity,economic proximity and cognitive proximity among cities.
