Spatial structure of Zhengzhou Airport Economy Zone: its evolution and drivers

摘要

This article uses ARCGIS software to conduct circle and hot spot analysis of enterprises within 10 km radius of Zhengzhou International Airport to track the evolution of the area and its spatial structure. First, we observed the industrial distribution around Zhengzhou International Airport, defined the airport's airport economic zone, and then analyzed the distribution of different airport-dependent industries in the inner, middle, and outer rings. As well as the distribution of industries of different industry classifications in the airport economic zone, combined with the characteristics of the airport economic zone, the dynamic mechanism of the airport economic zone is studied from both endogenous and external dynamics. The results show that, after decades of development, the airport has moved from a one-way expansion in the initial stage to a multi-directional expansion similar to urban areas. At the same time, the resident enterprises are from an increasing range of industries, pointing to a diversified development. Besides, the agglomeration pattern of enterprises is shifting from the airport center to the periphery as the dependence on the airport itself weakens. Industrial hot spots are gradually evolving from scattered points to axial lines. The layout of core industries around the airport and the transportation access has morphed into a "North-South development" pattern. The status of the airport hub, the functional zoning of the airport area, the control of the airport area, and the airport orientation of industry each affect the development and clustering patterns of the economic zone.
