文章从数字产业集群演化视角出发,结合区位商和社会网络分析法从中国302个城市中识别出36个数字产业集群;同时综合运用动态改进理想解法首次测算了数字产业集群发展水平,并通过整体与维度分析探究其区域差异及来源和分布动态.结果表明:①中国数字产业集群发展水平呈逐年增长趋势.②支持度及其增长率最高,是数字产业集群发展的"压舱石";关联度增长率最低,是最具潜力的发展点.③区域差异呈微弱缩小趋势,主要源自区域间差异和超变密度.④数字产业集群发展具有稳定性和俱乐部趋同特征.从趋势预测来看,中国数字产业集群随时间的推移而逐步提升,但近邻水平越高越影响本地发展水平向高值集中的趋势.因此,要创新数字产业集群合作模式,探究兼顾异质性与长效性的协调发展路径和完善区域间关联互动机制,以保障打造具有国际竞争力的数字产业集群目标的实现.
Evaluation of the Development Level of Digital Industry Clusters and Its Spatiotemporal Evolution
From the perspective of digital industry cluster evolution,this study identifies 36 digital industry clusters from 302 Chinese cities using the methods of the locational quotient and the social network analysis.It employs the dynamic improved TOPSIS to measure the development level of digital industry clusters,and explores their regional differences,sources,and distribution dynamics through overall and dimensional analysis.The research shows that:1)The development level of China's digital industry clusters has been increasing year by year.2)The support degree and its growth rate are the highest,serving as the"ballast"for the development of digital industry clusters,while the correlation degree has the lowest growth rate,representing the most potential development point.3)Regional differences show a slight narrowing trend,mainly originating from regional disparities and super-variable density.4)The development of digital industry clusters demonstrates stability and club convergence characteristics.From the trend forecasts,China's digital industry clusters are gradually improving over time,but the higher the neighboring level,the more it affects the trend of local development level concentrating towards higher values.Therefore,it is necessary to innovate cooperation models for digital industry clusters,explore coordinated development paths that balance heterogeneity and long-term effectiveness,and improve inter-regional interaction mechanisms,thereby creating digital industry clusters with international competitiveness.
