摘要
以绿色技术为代表的创新要素跨城自由流动是长三角生态绿色一体化建设的应有之意。基于2001—2020年绿色专利城际转让数据,文章分析了长三角绿色技术跨城流动演化特征,并从整体发展、绿色技术集聚和绿色技术扩散3个层面探讨了绿色技术跨城流动下的长三角生态绿色一体化发展程度。文章发现,长三角绿色技术流动是由沪苏锡常镇宁城市带和环杭州湾城市群构成的长三角城市群核心区为核心的承载空间,北京、天津和珠三角地区不仅是长三角绿色技术对外销售的主要承接地,也是长三角绿色技术对外需求的主要供应地;同时,绿色技术跨城流动下的长三角生态绿色一体化在整体层面和绿色技术销售层面已经实现,但在绿色技术供应链上快速衰退。文章系统论述了要素流动下长三角生态绿色一体化发展进程,提出加速长三角绿色技术流动的政策建议,以期为我国区域生态绿色一体化发展提供案例支撑。
Green technology innovation is the core driving force for the high-quality development of regional integration in the Yangtze River Delta,and the free flow of innovative elements represented by green technology across cities is the due meaning of the construction of ecological green integration in the Yangtze River Delta.Based on the inter-city green patent transfer data from 2001 to 2020,this study analyzed the characteristics of the spatial evolution of green technology diffusion in the Yangtze River Delta,and discussed the development degree of ecological green integration in the area from the three levels of overall development,green technology supply,and green technology sales.This study found that the core area of the Yangtze River Delta urban agglomeration,consisting of the Shanghai-Suzhou-Wuxi-ChangzhouZhenjiang-Nanjing urban belt and the Hangzhou Bay city agglomeration,is the core supporting space whether in terms of the intra-region green technology flow or inter-region green technology flow.Beijing-Tianjin area and the Pearl River Delta are not only the main external purchasers,but also the main external suppliers of green technologies in the Yangtze River Delta.The ecological green integration of the Yangtze River Delta under the inter-city green technology flow has been realized at the overall level and the green technology sales level,but it has rapidly declined in the green technology supply chain.
