Under the background of globalization and sustainable development of the world economy, it is the only way for China's current social development to achieve inclusive economic growth. Based on the theoretical analysis of financial development, technological innovation and inclusive growth, this paper empirically analyzes the impact of financial development on inclusive growth by using generalized moment estimation and Sobel intermediary effect test considering technological innovation. The results show that financial development has a positive impact on economic inclusive growth, while the scale, structure and efficiency of financial development have different effects on inclusive growth, Technological innovation is one of the intermediary ways for financial development to influence inclusive growth, Financial development has significantly promoted technological innovation, and has a positive effect on inclusive growth through it, Meanwhile, there is regional heterogeneity in intermediary effect. The benign interaction between financial development and technological innovation is helpful to promote the inclusive development of China's economy, humanities, society and environment, which accords with the theoretical analysis conclusion. Finally, this paper puts forward relevant policy suggestions for different regions from the perspective of financial development and technological innovation.
