%X Based on the National Census of Basic Units and an analysis of 161 postal districts in Beijing, this paper studies Beijing's layer structure of manufacturing between 1996 and 2001 and its driving forces.By taking density mutation and total quantity change of manufacturing employment as the criteria, Beijing can be divided into three layers: the central urban area with manufacturing decline has extended to the Fourth Ring Road; the suburban active region of both newly-built and relocated enterprises has rapidly extended to most of the plain areas; manufacturing growth in the mountainous outer suburban counties is still slow.The factor decomposition shows that the evolution of manufacturing layer structure is driven by electric and electronic industries, metal and non-metallic products industries, private enterprises and large and medium-sized enterprises. The adjustment of scale and industrial structure also plays a certain role. We also find the trend of intra-layer diversification and equalization of industries and inter-layer convergence of industrial structure. The middle layer to which the intensification of land use is of paramount importance will maintain its manufacturing superiority in a long period. Urban industries are recommended in the central urban area and ecological conservation should be the premise of outer suburbanization.
