Regional Economic Difference Analysis and Path Selection from the Perspective of Spatial Structure

By using of variation coefficient, Theil coefficient and clustering analysis method, this paper makes deep analysis on the regional economic differences in Sichuan from the perspective of spatial structure. The results show that: the 21 cities and districts show obvious difference in the aspects of economic aggregate, industrial structure, technology and employment, etc.; the regional economic differences are mainly caused by the differences between the five economic zones. The 21 cities and districts are divided into 8 classes of areas, distributed on the "two axes" and "two circles". The main axis includes the 1-5 classes of areas, which is the significant support of Sichuan's economy with big economic volume. The 6th class of areas includes 5 cities and districts, distributed on the subordinate axis which crosses over the main axis in X-shape. Many new growth poles are distributed in this class of areas. The 7th and 8th Classes of areas are distributed in two circles. Based on the above analysis and learning experiences from developed countries like the United States, France, Japan and Germany on the spatial strategy to narrow the regional difference, this paper puts forward path selection for implementation of multipoint and multipolar strategies.
