Based on the pole-axis spatial system theory and growth pole theory, 11 main economic indicators' data obtained from all the cities at prefecture level and above in 2008 were analyzed by employing principal component analysis to calculate the urban comprehensive score. Among all the cities, 100 top cities were selected as the primary cities. By choosing the sampled 100 cities as geographical centres, their economic impacting areas were determined by applying the spatial interaction theory, and meanwhile the urban economic influential radiuses were also explored, through buffer zone analysis in GIS. Taking the main railway lines, the main water distribution systems and the coastal boundaries as references, the average values of the radiuses of the primary cities which these axes running through were regarded as the economic influential radiuses to conduct the buffer zone analysis in GIS, and the top 10 primary axis impacting areas in China were named. Based on this, the primary economy axes in China were positioned through axes least-square method analysis. The results showed that cities located in the Beijing-Tianjin-Tangshan economic zone, the peninsula of Shandong economic zone, and Yangtze River Delta and Pearl River Delta economic regions have developed to an advanced city cluster development phase, the central-eastern part of China has stepped into a pole-axis web shaped development phase, while the western China has not yet formed the primary axis. By combining the actual situations in China and the results obtained through this research, suggestions for improving the Chinese primary axes were also proposed, and the levels of growth poles on the primary axes were categorized. Based on the improvement of the primary axis, the cities for future development were selected from the axes. Finally, the micro regional economic policies were discussed.
