改革开放以来，中国居民收入差距的持续扩大，不仅引起了全社会的巨大关注，更对中国的经济发展，尤其是向创新驱动的转型带来了严峻的挑战。本文从收入差距与技术创新关系这一独特的视角出发，突破了传统研究技术创新形式的不完全性、收入差距的不连续性、收入效应的同质性等局限性，在考虑了收入效应差异的基础上，创建了居民收入差距连续变化条件下的企业产品创新竞争模型，揭示了收入差距的变化通过“价格效应”与“市场规模效应”的耦合对产品创新产生的复杂影响机制，并通过数值模拟、计量分析等方法进行了验证。研究表明：收入差距（基尼系数）与企业产品创新存在复杂的非线性关系。“收入效应”较小时，“市场规模效应”占主导，收入差距与产品创新之间呈现负相关；当“收入效应”较大时，“价格效应”占主导，收入差距与产品创新正相关；“收入效应”处于中度值时，收入差距与产品创新是“U”型曲线关系。本文的方法与结论拓展了收入差距与技术创新关系的研究进展。
改革開放以來，中國居民收入差距的持續擴大，不僅引起瞭全社會的巨大關註，更對中國的經濟髮展，尤其是嚮創新驅動的轉型帶來瞭嚴峻的挑戰。本文從收入差距與技術創新關繫這一獨特的視角齣髮，突破瞭傳統研究技術創新形式的不完全性、收入差距的不連續性、收入效應的同質性等跼限性，在攷慮瞭收入效應差異的基礎上，創建瞭居民收入差距連續變化條件下的企業產品創新競爭模型，揭示瞭收入差距的變化通過“價格效應”與“市場規模效應”的耦閤對產品創新產生的複雜影響機製，併通過數值模擬、計量分析等方法進行瞭驗證。研究錶明：收入差距（基尼繫數）與企業產品創新存在複雜的非線性關繫。“收入效應”較小時，“市場規模效應”佔主導，收入差距與產品創新之間呈現負相關；噹“收入效應”較大時，“價格效應”佔主導，收入差距與產品創新正相關；“收入效應”處于中度值時，收入差距與產品創新是“U”型麯線關繫。本文的方法與結論拓展瞭收入差距與技術創新關繫的研究進展。

Chinese residents income gap has been increasing continuously since the reform and opening, which not only attracts much attention of all society, but also brings a great challenge to the development of China, especially to Chinese innovation driven road. From a special perspective of the relation between income gap and technical innovation, this paper overcomes the traditional limitations of the incompleteness of technical innovation forms, the uncontinuity of income gap, the homogeneity of income effect, and considering the difference of the income effect, this paper builds a product innovation competition model among firms under a continuous change of income gap, through which this paper deeply reveals the complex mechanism of the income gap change to product innovation, which comes from the coupling effect of “price effect” and “market scale effect”. Also this paper tests the theory through simulation and econometric analysis. The research shows ： there exists a complex nonlinear relationship between income gap（ Gini coefficient） and firms＇ product innovation. When “income effect” is small, the “market scale effect” is dominant, the relationship between income gap and product innovation is negative; when“income effect” is large, the“ price effect” is dominant, the relationship between income gap and product innovation is positive; when “income effect” is medium, it is a “ U” curve relationship between income gap and product innovation. The method and conclusion extend the current research about the relationship between income gap and technical innovation.
