中国高新技术产业已经取得了巨大进步,但仍然处于价值链低端,如何增加附加值提升在全球价值链的地位成为当前迫切需要解决的问题。基于动态网络DEA方法,本文计算了中国高新技术产业创新效率,结果发现,基于产值的中国高新技术产业创新效率不断提升,而基于专利申请的中国高新技术产业创新效率较低,与前者有很大差距,其主要原因是中国的高新技术产业融入国际垂直分工,进口中间产品在中国加工组装以后再出口,核心技术掌握程度较低,这就需要中国进一步鼓励自主创新、完善科技创新体制和加大知识产权保护力度。 China’s high-tech industry has made great strides but it is still at the low end of the value chain. How to increase the value-added of the high-tech industry in the global value chain has become an urgent issue to be solved. Based on the dynamic network DEA method, this paper calculates the innovation efficiency of high-tech industries in China and finds that the innovation efficiency of high-tech industries in China is continuously increasing based on output value. However, the innovation efficiency of high-tech industries in China based on patent applications is low, The main reason for this gap is that China’s high-tech industries are integrated into the international vertical division of labor. Imported intermediate products are re-exported after processing and assembly in China and their core technologies are mastered to a lesser degree. This requires China to further encourage independent innovation and improve the system of technological innovation Intellectual property protection efforts.
