Furthermore, a user-friendly statistical module, combining spatial statistical analysis methods with GIS visual techniques, is developed in Arcview using Avenue. An example is also given to show the usefulness of this module in identifying and quantifying the underlying spatial association patterns between economic units.展开更多

The study on the industrial location has become the focus of the massive theoretical location problems about agglomeration since the 1970s. The authors here analyze the evolution and the characteristics of the Industrial Agglomeration Theory and study its effect on the reconstruction of industrial location. The study suggests that the new idea ofrecoustmction of industrial location is to cultivate regional innovative system. On this basis, the authors analyze two cases of old industrial bases on their constniction-Tiexi Industrial District in Shenyang City and Changchun Industrial Economic Development Zone. Finally, the authors put forward some suggestions that should be regarded, which include： 1） to combine industrial location reconstruction and enterprises＇ inner reform; 2） to speed up adjustment of resources and opening to the world; 3） to combine government mechanism with the market mechanism properly.展开更多
