摘　　要：烟台市海洋经济近年得到较快发展,关于烟台市海洋产业的研究增多,而对海洋产业结构的时间聚类研究较少,研究和探索烟台市海洋产业的发展能够为规划、设计和建设半岛经济区提供一定的参考。基于烟台市海洋产业总产值、产业结构比例和各代表性产业产值与产量发展变化,进行相关分析后利用系统聚类法和K均值聚类法对年份和代表性海洋产业进行聚类,分析海洋产业发展的时间阶段变化特征。结果表明:烟台市海洋产业发展较快,海洋产业产值稳定增长,但存在不稳定因素使得个别产业产值与产量波动幅度较大;产业结构不断优化调整,重心逐渐向二、三产业转移;各产业发展速度不同,近年整体呈放缓趋势。The marine economy of Yantai has achieved rapid development in recent years,and studies on the marine industry in Yantai have increased.However,there is limited research on the temporal clustering of the marine industry structure.Researching and exploring the development of marine industry in Yantai can provide certain reference for the planning,design,and construction of the peninsula economic zone.Based on the output value,proportion of industrial structure,and the development of representative industries in marine industry of Yantai,this study utilizes the method of systematic clustering and K-means clustering to cluster the years and representative marine industries and analyze the temporal stage characteristics of the development of the marine industry after conducting relevant analysis.The results show that the marine industry in Yantai has developed rapidly with a stable growth in output value,but there are unstable factors that lead to significant fluctuations in the output value and production of individual industries.The industrial structure is continuously optimized and adjusted,and the focus is gradually shifting to the secondary and tertiary industries.The development speeds of different industries vary,and the overall trend in recent years shows a slowdown.
