Abstract:

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.

Key words: economic technological development area, spatial pattern, manufacturing industry, coastal area, China
