Abstract：Taking the cross-provincial patent literature of China mainland from 1991 to 2010 as sample,the paper studies the characteristics and spatial structures of the interregional technology collaboration networks.The results show that the networks have been more and more complex and the space disproportion exists.There are core-periphery structures in the networks.Besides,the collaboration pattern of eastern and central region have been more and more mature,however,the western region has not yet formed a stable cooperation relationship.As a result,China should continue to encourage the industry shift to central and west areas and dispatch resources appropriately to reduce the difference on space
