Abstract:

In 2015, China proposed the coordinated development strategy of the Beijing-Tianjin-Hebei region. Industrial coordination is the first area to promote this strategy. Therefore, the agglomeration and dispersion of industries in this area have received extensive attention from academia. This study used the Duranton and Overman (DO) index to examine the spatiotemporal change characteristics of manufacturing industry agglomeration in the Beijing-Tianjin-Hebei region from 2004 to 2013, and compared the differences by sub-region, industry, and firm, based on the data with the spatial location of the firms from three economic censuses. First, the agglomeration ratio of manufacturing industry in the Beijing-Tianjin-Hebei region increased from 69.0% to 82.8%, and agglomeration mostly occurred in the short-distance range of 0-50 km. As the scope of agglomeration gradually expanded, the intensity of agglomeration gradually weakened with a decrease of 25.9%. Second, at the regional level, agglomeration was more likely to occur in Beijing and Tianjin with higher level of economic development; at the industry level, agglomeration was more likely to occur in technology-intensive and labor-intensive manufacturing industries; at the firm level, agglomeration was more likely to occur in small firms while large firms were also prone to agglomerate in extremely short distance (0-25 km). Third, there was a trend of the manufacturing industry spreading from Beijing and Tianjin to Hebei Province in this period, especially some manufacturing industries with low technological level and great labor demand. Therefore, it was appropriate to propose a coordinated development strategy at the time. In the process of industrial deconstruction and transfer, differentiated policies considering differences in industry and scale should be formulated.
