基于Logistic模型的船舶产业集群稳定性分析

采用生物学中Logistic模型,描述了船舶产业集群的构成实体及其产出水平,分析了船舶产业集群在稳定状态时各构成实体之间关系;得到两个重要的均衡条件:(1)集群内分工程度高、企业间的竞争激烈,核心造船厂的规模大,并且对单个中小配套企业产出水平的贡献相对较大;(2)单个中小配套企业供应的物料仅占核心造船厂产出水平有限的比例,对核心造船厂产出水平的贡献相对较小。

The logistic model is applied in this paper to illuminates the shipyards ＆ matching enterprises and their output. The relationship of the shipbuilding industrial cluster in stability is analyzed. The equilibrium conditions are acquired： The cluster＇ degree of the division of labor is high, and the scope of shipyard is huge, then the contribution to its matching enterprises＇ output is large, whereas the matching enterprises＇ eontribution to which is little.
