Abstract:

Development zone is the spatial carrier and the growth pole of regional industrial agglomeration and development. Studying the spatial pattern and industrial agglomeration characteristics of the development zone is of vital importance to the layout optimization of the development zone, the industrial division and cooperation, and the high-quality development of the regional economy. In this article, the nearest neighbor index, Ripley's L function and kernel density estimation were adopted to analyze the spatial distribution and industrial agglomeration characteristics of development zones in the Yangtze River Economic Belt. The results show that: 1) On the whole, the development zones of the Yangtze River Economic Belt show a distribution characteristic of remarkable agglomeration, which is characterized by ‘sparse in the east and dense in the west, the east strong west weak and differentiation in the east, the middle and the western region’; 2) The spatial distribution of various industry-oriented development zones is agglomeration, while its agglomeration intensity and scale are significantly different, showing the principle of ‘increased firstly and decreased later’; the cluster forms are different, mainly including three types: ‘single core’‘dual core’ and ‘multi-core’; 3) The eastern part of the Yangtze River Economic Belt mainly focuses on capital and technology-intensive industries such as equipment manufacturing, communication electronics, automobile manufacturing, new materials, biomedicine, while the central and western regions concentrate capital and labor intensive industries such as chemical industry, metal processing, food manufacturing, textile and clothing. 4) Great efforts are in need to strengthen the multi-dimensional and benign interaction between the mid- and lower-stream development zones in the economic belt, promote green development, innovation development and structural optimization, and further enhance its leading and supporting role in the high-quality development of the Yangtze River Economic Belt.

Key words: development zones, leading industry, industrial agglomeration, the Yangtze River Economic Belt
