摘要：金砖国家经济高速增长伴随着收入差距的持续扩大引发了增长可持续性的担忧。文章基于DEA方法对金砖五国2000—2011年全要素生产率、前沿技术进步和技术效率进行测算，并利用固定效应面板数据模型探讨收入差距与技术创新的内在关系发现：收入差距与全要素生产率和前沿技术进步之间呈显著的倒u型关系，与技术效率呈显著的负相关关系，因此，激励技术创新存在一个收入适度差距问题。当前金砖国家中南非、巴西和中国用基尼系数所衡量的收入差距已经超过倒u型曲线顶点的临界值，采取切实有效的措施减小收入差距，促进国内需求和激励技术创新是保持经济持续增长的关键举措。

The rapid economic growth along with the widening income gap has caused concerns about the growth sustainability of the BRICs countries. By employing DEA technique to calculate the total factor productivity, technology changes and efficiency changes of BRICs countries in 2000-2011, and using fixed effect panel data model to investigate the relationship between income gap and technology innovation, this research finds that the relationship between in- come gap and the total factor productivity and technology changes takes on a sig- nificantly inverted U-shaped curve, while income gap is in significant negative correlation with technical efficiency. Therefore, a moderate income gap is desir- able to stimulate technology innovation. As the income gaps of South Africa, Bra- zil and China have exceeded the critical values at the vertices of the inverted U-shaped curve at present, this paper suggests that China take concrete and effec- tive measures to reduce income gap, boost domestic demand and encourage tech- nology innovation in order to maintain sustained economic growth.
