R&D要素价格扭曲对中国制造业创新效率的影响:全球价值链地位视角

The Effect of R&D Factor Price Distortion on the Innovation Efficiency of Chinese Manufacturing Industry: From the Perspective of Globe Value Chain Status

文章选取2003~2014年的中国制造业数据,运用随机前沿分析法测算了中国制造业的创新效率,通过构建包含进口中间品的C-D生产函数测量了R&D要素价格扭曲,进一步从全球价值链地位视角实证分析了R&D要素价格扭曲对创新效率的影响。结果表明:R&D要素价格扭曲抑制了制造业创新效率的提升;在与全球价值链地位的交互作用下,R&D劳动力和进口中间品价格扭曲会负面影响创新效率,而R&D资本价格扭曲会正面影响创新效率;在劳动密集型制造业中,R&D要素价格扭曲对创新效率的作用大于其在资本技术密集型制造业中对创新效率的作用,且R&D要素价格扭曲与全球价值链地位的交互作用对创新效率的影响较大。

Based on the panel data of manufacturing industry in China from 2003 to 2014, this paper uses stochastic frontier analysis method to measure the innovation efficiency of Chinese manufacturing industry, and constructs the C-D production function including imported intermediate products to measure R&D factor price distortion, and further empirically analyzes the effect of R&D factor price distortion on innovation efficiency from the perspective of global value chain position. The results show that R&D factor price distortion inhibits the improvement of innovation efficiency in manufacturing industry. The price distortion of R&D labor and imported intermediate products negatively affects innovation efficiency, while the price distortion of R&D capital positively affects innovation efficiency. In labor-intensive manufacturing industry, the effect of R&D factor price distortion on innovation efficiency is greater than that of capital and technology intensive manufacturing industry, and the interaction between R&D factor price distortion and global value chain position has a greater impact on innovation efficiency.
