本文从需求视角分析了收入不平等对技术创新的影响,其机制主要包括“规模效应”、“价格效应”以及“结构效应”三种效应。在此基础上,文章采用1992-2012年中国国家层面数据对“规模效应”和“结构效应”进行了实证检验,研究发现:收入不平等总体上抑制了中国自主创新能力的提升;需求规模效应促进了较低层次的技术创新,却由于对技术含量较高产品需求的不足,抑制了中国高层次创新产品的研发;收入不平等引起的结构效应也阻碍了技术创新活动的进行。
This paper analyzes the impact of income inequality on technological innovation from the perspective of demand. The mechanism mainly includes three effects: “scale effect ”, “price effect ” and “structural effect ”. On this basis, the article uses the data of China national level from 1992 to 2012 to test the effect of “scale effect” and “structure effect”. The study finds that income inequality generally inhibits the improvement of China’s independent innovation capability ; The demand-scale effect has promoted the technological innovation at a lower level but has inhibited the research and development of China’s high-level innovative products due to the lack of demand for high-tech products; the structural effect caused by the income inequality has also impeded the technological innovation activities .
