中国不同行业全球价值链位置对创新效率的影响

关注中国各行业全球价值链位置对创新性效率的影响，基于新古典经济理论提出假设，采用非竞争性投入产出法计算中国19个代表性行业在全球价值链中的位置及变化趋势，测算其整体创新效率。进一步将创新效率分解为技术进步指数、规模效率指数、纯技术效率指数，通过观察分解变量值揭示行业差异。结果表明：研发阶段，处于全球价值链上游的行业，行业技术前沿水平上升，行业整体向前沿靠近的程度降低；生产阶段，处于全球价值链上游的行业，行业技术前沿水平下降，行业整体向前沿靠近的程度上升。

The Impact of Position in Global Value Chain on China's Innovation Efficiency

The paper aims to analyze the impact of China's postion in global value chain on innovation efficiency, we use New Classical Economic Theory to make assumptions. We use non competitive input output method to calculate 19 representative industries' positions in global value chain, then we calculate 19 representative industries' innovation efficiency, and it is decomposed into technical progress index, pure technical efficiency index, and scale efficiency index, and industrial differences can be observed in the decompostion. On the basis of empirical results, in the research and development stage, China's industries in global value chain have positive effect on the technological frontier, and it can widen gap between the whole level and technological frontier. In the production stage, China's industries in global value chain have negative effect on the technological frontier, and it can narrow gap between the whole level and technological frontier.
