Green finance is an important means and tool to promote the country's green development.Selecting the data of provincial levels from 2012 to 2021, the industrial transformation level of each province was taken as the logical starting point, a panel regression model was established to empirically investigate the specific correlation between green finance and industrial transformation, and the relationship between green finance and energy consumption per unit of industrial added value as well as industrial transformation and upgrading was deeply analyzed.It is found that green finance has a significant promoting effect on industrial green transformation, and further analysis shows that green finance mainly helps industrial enterprises in green transformation by reducing energy consumption per unit of industrial added value.Finally, countermeasures and suggestions are proposed at the level of government policies, financial institutions and enterprises themselves as the logical end point to promote the development of the real economy.
