Abstract: In the first decade of this century, Beijing has been undergoing the conversion from an industrial city to a new economic city which is more suitable for the capital city, and the transfer will have a profound and far-reaching influence on the distribution of the manufacturing in Beijing. This paper intends to represent the spatial evolution of manufacturing in Beijing in recent 10 years, using the methods of functional zonation and center of gravity calculation. In addition, by decomposing the change of the center of gravity, we also try to describe quantitatively some factors which affect the distribution of manufacturing. Firstly, by collecting and processing the statistical data of the manufacturing in Beijing, we found that the spatial distribution of manufacturing in Beijing had been expanding from the function extension area to the new urban area, and the centers of gravity of both manufacturing employment and enterprises in Beijing extended eastward. However, there are also some differences: the former to the northeast, the latter to the southeast. Secondly, we decomposed the change of the center of gravity to three effects. The result shows that both the structure effect and the spatial effect play more important roles in the change of the center of gravity of manufacturing employees, which were the dominant driving force for the change of the center of gravity of manufacturing in Beijing. It is concluded that, on one hand, we should carry out the readjustment of industrial structure, to transfer from the labor-and capital-intensive heavy chemical industries to the knowledge-and tech-intensive high-tech industries, such as manufacture of electronic and communication equipment and manufacture of computers and office work equipment; on the other hand, we should further optimize the spatial distribution of the manufacturing in Beijing, so as to shape a new closer industrial pattern among Beijing, Tianjin and Hebei province.

Key words: Beijing, center of gravity, decomposition, manufacturing distribution
