Abstract: Assuming the knowledge spillover of high-tech regions on low-tech regions is greater than that of low-tech regions on high-tech regions, and introducing this hypothesis into the regional economic growth model with spatial knowledge spillover equation, we study the effect of spatial knowledge spillover on regional economic growth. Our model suggests that regional total output is spatially autocorrelative, neighboring region’ s labor inputs have a negative effect on local total output, and neighboring region’s R&D inputs have a positive effect on local total output due to spatial knowledge spillover. Constructing spatial technology weight matrix to describe spatial knowledge spillover, and doing spatial econometric regressions using China’ s provincial panel data, our empirical results verify the inferences of the theoretical model. This implies that the phenomena of labor reflow in central and western China and the upsurge of “Innovation and Entrepreneurship” are conducive to improving the knowledge spillover effect of the eastern region on the central and western regions, thus promoting the common economic development of the central and western regions of China.
