Abstract: Use panel data sets collected from five high-tech industries in Chinese 31 provinces through year 1995-2010, this study examines effects of geographical proximity, technological proximity and combined proximity on inter-provincial knowledge spillovers respectively by spatial panel data analysis. The empirical results indicate that, first, estimations of spatial panel data analysis is more precise than that of common panel data analysis. Second, R&D capital contributes more than R&D labor on knowledge production. Third, whether under geographical proximity or technological proximity, the presence of Chinese inter-provincial knowledge spillovers in high-tech industries is much evident, in which technological proximity has a little more effects, but the effects of combined proximity is not sufficient as presumed. The estimation varies with different model specifications and its implications are discussed.
