英文摘要：

This paper discusses new regional specialization and its influence on economic growth when involved in international intra- product fragmentation. The findings ~inly show that, compared with more apparent specialization based on intra- production fragmentation for eastern regions, specialization based on international inter- and intra- industry fragmentation is more apparent for middle and western regions. Finally, it points out that when taken into account space dependence, influence of new regional specialization remains positive on regional economic growth through comparative advantages and economies of scale.
