以粤港澳大湾区点尺度的发明专利空间数据为基础,通过建立战略性产业与专利IPC分类号之间的联系,提取了大湾区6类主要行业的发明专利,利用核密度分析、标准差尾值检验、熵值法和平均最邻近距离分析等方法,识别粤港澳大湾区多类型技术创新的空间分布特征与差异.结果表明:粤港澳大湾区技术创新的地理格局呈现显著的空间不均衡性,区域尺度形成了广州与深圳2个集聚核心,珠江东西两岸在创新能力上存在较大差距,技术多样性的区位主要分布在大湾区核心城市的核心区;新一代电子信息、先进材料、绿色石化3类产业的创新占大湾区整体的51.67%,不同技术类型的创新在空间上呈现显著分异,主要集中在广州、深圳、东莞、珠海的核心区,其中,新一代电子信息产业创新的空间集聚度最高.

Easy access to accurate and reliable climate data is a crucial concern in hydrological modeling.In this regard,grid-ded climate data have recently been provided as an alternative to observational data.However,those data should be first evaluated and corre
区域协同发展是新时期粤港澳大湾区提升国际竞争力、建设国际一流湾区和世界级城市群的关键,也是一项与时俱进的科学议题.之所以讲“与时俱进”,是因为,协同发展对于粤港澳大湾区(或者说大珠三角城市群)并非一个新的话题.上世纪80年代以来,众多人文地理学者围绕粤港澳区域合作、区域联动和一体化发展等议题展开了大量卓有成效的研究,揭示了粤港之间“前店后厂”的区域协同模式.“前店后厂”作为标志性的模式,深入地揭示了改革开放以来粤港澳协同发展的内涵,也获得了学术界的广泛认同.然而近20年来随着合作模式的全方位推进,今天已很
