我国沿海船舶工业空间集聚适度性研究

摘要：在船舶市场收紧与产业结构低端的背景下，研究集聚适度性对船舶产业高质量发展具有现实意义。运用区位熵和突变模型对沿海地区船舶工业集聚度和集聚效率进行测算，并通过比对分级研究了区域整体和各省（市，自治区）间集聚适度性状态。结果显示地区间集聚度和集聚效率差异较大，且二者相关性明显，由于各省（市，自治区）条件不同导致集聚适度性区域差异明显，最后提出了政策建议。

Research on Space Gathering Moderate of the shipbuilding Industry in Coastal Regions

Abstract: Under the background of tighter market and low-level industrial structure, it is practical significant to study the space gathering moderation for the high-quality development of shipbuilding Industry. This paper uses the location quotient and catastrophe model to calculate the degree and efficiency of shipbuilding industry agglomeration in coastal regions, and studies the agglomeration moderation state among overall region and inter provincial use the methods of comparison and classification. The results show that there are significant differences in the degree and efficiency of agglomeration among regions, and the correlation between them is significant. Due to the different conditions of each province, the space gathering moderation are significant. Finally, policy recommendations are put forward.
