Abstract：
Based on the framework of MRW models, this paper introduces human capital into the overall production function. After presenting the database of 409 counties from 1995 to 2015 and the spatial weight matrix which is used to model the spatial connections between all the counties in the sample, this paper builds a parameter heterogeneity equation that includes the steady income level and conditional convergence, then it focuses on studies of the influence on economic growth inserted by steady physical capital, human capital and technical diffusion by using recently developed technique of spatial econometrics. It is found that the stock of technology in one county produces externalities that may cross county borders and spill over into other counties with an intensity which decreases with distance. With its notable impact on economic growth, human capital has credible spillover effect in all the counties.
