Abstract: The interactive and integrated development of equipment manufacturing industry and producer service is an important way to enhance the industrial innovation ability and climb to the high end of the industrial value chain.Based on the data of 2009-2017 in China, this paper uses system dynamics to simulate the effectiveness of the financial policy of the interaction and integration of equipment manufacturing industry and producer service. The results show that the effectiveness of the existing financial policy has heterogeneity；the reduction of enterprise income tax rate hinders the integration of the two industries,the effectiveness of government investment expenditure policy is relatively small, at present, the government′s science and technology investment policy is invalid, while the government′s education expenditure policy plays the most significant role in promoting the integration of the two industries. The above conclusions have reference value for the optimization of relevant financial policies.
