Abstract: Convergence of region economics has been a focus of development economics. The paper probes the driving effect of technology on economic convergence of 30 provinces in China during 1999-2010 based on constructing the measurement model of R&D marginal productivity. The research results show that there exists significant driving effect of R&D marginal productivity on regional economic convergence in China, and there is one-period lag when R&D marginal productivity driving economic convergence. The research also finds that the R&D input in Eastern economic region is excessive, the input in Western region is not enough, and the input in Middle region shows relatively reasonable.

摘要： 区域经济收敛性一直是发展经济学研究的热点问题之一。本文在建立R&D边际生产力的测量模型基础上，探讨了中国30省市1999-2010年间R&D边际生产力对区域经济收敛的驱动效应。研究结果表明R&D边际生产力对区域经济收敛存在显著的驱动效应，并且R&D边际生产力驱动区域经济收敛存在1期滞后。研究还发现东部R&D投入过量，西部R&D投入不足，中部R&D投入比较合理。
