【摘要】：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。
[Abstract]:Since the reform and opening up, the continuous expansion of the income gap of Chinese residents has not only aroused the great concern of the whole society, but also brought severe challenges to China's economic development, especially to the transition to innovation-driven economy. From the perspective of the relationship between income gap and technological innovation, this paper breaks through the limitations of the traditional research on the incompleteness of technological innovation, the discontinuity of income gap, the homogeneity of income effect, etc. On the basis of considering the difference of income effect, the competition model of enterprise product innovation under the condition of continuous change of resident income gap is established. This paper reveals the complex influence mechanism of the change of income gap on product innovation through the coupling of "price effect" and "market scale effect", and verifies it by numerical simulation, econometric analysis and so on. The study shows that the income gap (Gini coefficient) has a complex nonlinear relationship with enterprise product innovation. " When the income effect is small, "market scale effect" is dominant, and the income gap is negatively correlated with product innovation, and when "income effect" is larger, "price effect" dominates. The income gap is positively correlated with product innovation, and when the income effect is in a moderate value, the income gap and product innovation are "U" curve. The methods and conclusions of this paper extend the research progress of the relationship between income gap and technological innovation.
