This paper uses SFA technique to measure the regional R&D technical efficiency in China during 1999～2008, applies spatial measurement economics technique to analyze the correlation and convergence characteristics, and builds a spatial convergence model to analyze the spatial convergence characteristics of the technical efficiency of regional R&D. The analysis result shows that there appears positive correlation characteristic and an absolute convergence trend on the regional R&D technical efficiency in China, and the effect of spatial geographical factors on the regional R&D technical efficiency is significant.
