采用产业网络上的K-核关联结构方法识别关键产业群,通过关键产业群的产业关联强度与产业关联结构两方面异质性来进行“鲁粤”二省产业结构的区域比较。依据产业网络理论,归纳了关键产业群的形成与作用机理,提出了关键产业群识别的“k-核度基准”识别方法并设计了相应指标体系,并对“鲁粤”二省关键产业群做了实证和比较分析。研究结果表明:“鲁粤”二省关键制造业群、生产性服务业以及能源工业等关键产业群构成上差异明显;两省关键产业群的“集聚效应”与“扩散效应”等产业关联特征表现恰好相反;而在关键产业群对地区国民经济的影响上看,“鲁粤”二省均呈现出制造业的总体影响较大,而生产性服务业的总体影响较小的特征。
The key industrial clusters were identified by the method of K-nuclear association structure on the industrial network. The regional comparison of the industrial structure of the two provinces of “Lu Yue” was conducted through the heterogeneity of the industrial correlation intensity of the key industrial clusters and the industrial related structure. According to the theory of industrial network, the formation and mechanism of key industrial clusters are summarized, and the method of identification of key industrial clusters is proposed and the corresponding index system is designed. The key industrial clusters in the province made empirical and comparative analysis. The results show that there are significant differences in the composition of the key industrial clusters such as key manufacturing group, producer service industry and energy industry in the two provinces of Lu “Yue”; the “agglomeration effect” and “diffusion effect” of the key industrial clusters in the two provinces However, in the impact of key industrial clusters on the national economy in the region, the two provinces of “Lu Yue” all showed a greater overall impact on the manufacturing industry, while the overall productivity of the service industry Less affected features.
