Interindustry R&D Spillovers and Productivity: Evidence from China High-Tech Industries

This paper deals with the estimation of the impact of interindustry R&D spillover on productivity growth using the panel data of China high-tech industries during the period of 1999-2006. We can find that inter industry R&D spillover has improved the industry´s TFP growth, The contribution of interindustry R&D spillovers from pure knowledge to TFP growth and efficiency (EC) growth is highly positive correlated, the estimated coefficient is 0.20-0.26, The estimated coefficient of interindustry rent spillovers on TFP growth and EC growth is 0.11 to 0.20, the effect of pure knowledge spillovers is slightly larger than rent spillovers´ effect . However, the effect of interindustry R&D spillover regardless of rent spillover and knowledge doesn´t improve technical progress (TC); It´s the industry´s R&D capital stocks that promote the industry´s technical progress.
