摘要
立足产业生态网络演进视角,提出集聚向集群演进的"聚点-连线-拓面-成体"四阶段;提出了不同阶段集聚水平测度和跃升机制相结合的"静态-动态"系统研究框架;选取中国新能源汽车的"双子星"集群,即上海和广州新能源汽车产业集群进行了验证.结果表明:从集聚水平来看,上海和广州均处于"成体"阶段,但供应链网络密度和企业协同创新有待提升;从跃升路径来看,上海和广州均遵循了从"龙头企业引领,协作配套紧密"到"核心技术引领,激发创新活力"再到"创新服务完善,区域品牌显现"的发展路径.
Abstract
Based on the perspective of industrial ecological network evolution,the paper puts forward four stages of agglomer-ation to cluster evolution,namely"point-line-plane-solid".A"static and dynamic"system research framework is pro-posed,which combines the measurement of agglomeration level at different stages with the mechanism of jump,using China's new energy vehicle"twin star"cluster,namely Shanghai and Guangzhou new energy vehicle industry cluster,for verification.The results show that,from the agglomeration level,Shanghai and Guangzhou are both in the"adult"stage,but the supply chain network density and enterprise collaborative innovation need to be improved;from the perspective of the jump path,Shanghai and Guangzhou have followed the development path from"leading enterprises,close cooperation and supporting"to"leading core technologies,stimulating innovation vitality"to"improving innovative services,and showing regional brands".
