Abstract: Introduce the technology gap to endogenous technology growth model, and with our country region in panel data of 1997-2013, to examine the relationship of the technology gap, economic growth and economic convergence. The results show that: (1) Technological progress shows inverted V-shaped direction and area’s feature is outstanding, the technology gap and economic growth exists nonlinear relation, and the threshold effect is remarkable. Among these, the eastern region is generally located in the left of the threshold and the central and western regions are in the right. (2) The macro economics and regional economics behave the convergence and club convergence respectively, and the eastern average annual convergence speeds faster than the western region’s, and the technical gap increase will hinder technological progress and growth. Therefore, areas of our country should pinpoint their technology level and economic level, and select technology which corresponding their resources endowment; the minority of developed eastern areas which has across the threshold of the technology gap should pay more attention to independent innovation; and adjust the structure of human capital in order to fit physical capital accumulation, economic development level and the level of technology introduction, guide human capital from the eastern developed regions to central and western regions, strengthen basic education and construct multi-level education system, guarantee the long-term effectiveness and multi levels of human capital, training professional experts in order to solve the imbalance between supply and demand.
