An Empirical Study of Shipbuilding Industry Cluster Based on Complex Network

This paper uses the research method about complex network, and constructs the complex network of shipbuilding industry cluster in Shandong, and analyzes the statistical characteristics of network. The result shows that: there exist five cluster areas of important hub node in network, namely, Qingdao, Yantai, Weihai, Rizhao and Jining; node degree obeys power-law distribution; through continuous evolution and development, a more mature shipbuilding industry chain is gradually forming in Shandong, and agglomeration effect is obvious. It also finds that there are still some deep-seated problems and constraints in shipbuilding industry cluster in Shandong.
