| Since the implementation of the innovation driven strategy,China’s innovation strength has been continuously enhanced,and the industrial economy has developed rapidly;At the same time,issues in the field of income distribution are gradually becoming prominent,and income inequality is constantly worsening.Among them,the income inequality among industries is the largest,which is also the most concerned area of the society.It has a great impact on individual development.In the long run,it is not conducive to the stable development of the entire economy,not to mention the realization of the goal of common prosperity proposed in the 14 th Five Year Plan.Will the development of regional innovation in China lead to the widening of industry income gap? What is the reason behind it? In the context of the digital economy,how can digital means be used to alleviate it? After reviewing relevant literature and theories,clarifying the concepts and measurement methods of regional innovation and industry income gap,this article uses two research methods:theoretical analysis and empirical research to demonstrate.At the theoretical analysis level,this article is based on Galbraith’s "technology monopoly theory" and efficiency wage theory,and concludes that regional innovation affects industry income inequality through two mechanisms: monopoly effect and capital allocation effect.Specifically,enterprises that achieve technological innovation in one industry will form a technology intensive oligopoly,which will lead to technological gaps with other industries;Moreover,the industries that achieve innovation occupy most of the financial capital and human capital needed for innovation by virtue of their profit advantages,resulting in the capital gap between industries;In other words,the improvement of the overall regional innovation level does not indicate that each industry in the region achieves innovation with relatively equal innovation factors,thus forming an income gap between industries.In order to break through the flow barriers of innovative elements,it is necessary to practice the "long tail theory".In the context of the digital economy,digital inclusive finance enhances innovation and human capital by helping long tail customer groups in lowincome industries;And attract highly skilled talents to start their own businesses,provide technical support for other industries,and thus alleviate the relationship between regional innovation and industry income gap.At the empirical analysis level,based on the provincial panel data from 2011 to 2019,this paper mainly calculates regional innovation by the number of invention patent applications by province and year,calculates the industry income gap by the Gini coefficient of the average salary of employees between provinces and years,and constructs a double logarithm linear model and a single panel threshold model for empirical testing.Through the benchmark regression and robustness test,this paper concludes that improving regional innovation significantly expands the industry income gap;Then,through heterogeneity testing,it can be concluded that in regions with higher levels of marketization and more eastward geographical locations,regional innovation has a more significant role in expanding industry income disparities;However,in areas with high levels of development in the Yangtze River Economic Belt and digital inclusive finance,the role of regional innovation in expanding industry income disparities is not significant;On this basis,through the threshold effect test,it is concluded that digital inclusive finance can alleviate the widening industry income gap caused by regional innovation.According to the research conclusion,this paper puts forward suggestions from the three perspectives of the government,financial institutions and other innovation subjects,so as to promote China to narrow the industry income gap and achieve common prosperity as soon as possible under the condition of ensuring the level of innovation. |
