Abstract: This paper quantitatively analyzes the current situation，achievements，and impact mechanisms of green innovation development in the Yangtze River Economic Belt from 2017 to 2020 Using the economic“inputoutput”analysis framework，the study takes cities as the object and evaluates the level of green innovation development in the Yangtze River Economic Belt from eight dimensions，and empirically tests the promoting effect of green innovation inputs on outputs The research finds that the level of green innovation development in the 110 cities along the Yangtze River Economic Belt shows an overall upward trend Green innovation inputs in different dimensions have significantly different effects on green innovation outputs，and the promotion of innovation systems has the greatest effect Increasing local financial support for innovation system promotion and research and development expenditure can effectively enhance the promoting effect of innovation system and R&D investment on green innovation outputs，and maintaining the stability of innovation systems and R&D investment is the key to achieving output promotion effects This study deepens and enriches the application research of green innovation development and provides new ideas and helpful insights for promoting green innovation development in the Yangtze River Economic Belt
