中文摘要：

经济技术开发区是中国经济增长关键节点,也是产业发展的重要载体。本文通过收集整理东部沿海地区国家级和省级经济技术开发区基础数据,采用GIS空间分析技术,运用多距离空间聚类分析和核密度估计方法,研究分析了1996-2013年间中国东部沿海地区经济技术开发区的空间格局演变规律以及产业集聚类型特征。研究结果表明：①沿海地区开发区空间集聚程度增强,呈现出由“多中心集聚”向区域“单中心集聚”的演变规律。②开发区空间集聚规模和强度呈现出先降低后快速提高的趋势,表明空间集聚范围扩大,但是集聚程度并没有降低,反而随着集聚范围的扩张其集聚强度也进一步加强。③各集聚区域的集聚规模和集聚强度存在明显的差异,集聚规模最大的区域集聚强度却较小。④东部沿海开发区主要发展产业为装备制造业、纺织服装业、通信电子、食品行业、石油化工共五大类行业,各类型产业分布格局差异显著。

英文摘要：

Economic technological development area （ETDA） is not only the critical growth pole of China＇s economic development, but also an important carrier of industrial development. This paper explored the spatio-temporal pattern of national and provincial economic and technological development areas, and the characteristics of industrial agglomeration in the eastern coastal region of China during 1996-2013, using the multi-distance spatial cluster analysis and kernel density estimation method in ArcGIS. The results showed that：（1） The distribution of economic technological development areas presents a concentrating trend, with the spatial pattern changing from the poly-centric agglomeration to the single-center agglomeration. （2） The scale and intensity of spatial concentration decreased first and then increased rapidly, which indicated that the intensity of spatial concentration was further strengthened, as the scale of spatial agglomeration expanded. （3） The agglomeration scale and degree in each agglomeration region have large differences, and the areas with the larger scale of spatial concentration prefer to smaller intensity of spatial concentration. （4） Economic technological development areas in the eastern coastal region have larger advantage in equipment manufacturing industry, textile and garment industry, the electronic communications industry, food industry, and petrochemical industry, but the spatial patterns of these industries are quite different.
