Abstract：Under the background of dual carbon,it is very important to clarify the dynamic relationship between financial and technical expenditure,green technology innovation and carbon productivity of government decision-making.From 2006 to 2020,the panel data of 30 provinces in China were used to measure the above problems when using the Panel Vector Regression Model(PVAR).The results show that the fiscal expenditure on science and technology has played an effective role in promoting the improvement of green innovation level,but it is also timely.The government has further increased the expenditure on science and technology while encouraging the improvement of green innovation level,and there is a good mutual promotion relationship between them.The improvement of expenditure and green innovation level in finance technology will greatly promote the improvement of regional carbon productivity,and the impact of green technology innovation will be lasting and the contribution rate will be higher.Finally,on the basis of the above achievements,the government should encourage green technological innovation,increase financial support for scientific and technological innovation,accelerate the construction of low-carbon economy,and form a virtuous cycle model of the three.
