By using spatial autoregressive process to formulate the disembodied knowledge which can spillover between different areas,but omitted in classical linear model of international R&D knowledge spillover,the Spatial Durbin Model is developed with nonlinearity to quantify the disembodied knowledge spillover both into local area and its neighbors. Based on Chinese sample,result shows that local spillover effect is contrary to that of cross-regions,which is significant in statistics. The cross-regional spillover from service trade is the greatest and most robust,and that from FDI is greater than go...
