As the world’s first import-themed national expo，China International Import Expo（CIIE）is not only a window for China to build a new development pattern and a platform to promote high-level opening up to the outside world，but also an important channel and hub to promote the deep integration of digital economy and real economy in China. Fiscal and tax policies under the scenario of CIIE are becoming an “accelerator” to promote the development of China’s real-digital integration. In this process，the combination and matching of fiscal and tax policies still face many challenges，which are mainly reflected as follows：the fiscal and tax policies supporting the integration of data and reality have not been normalized and systematic，and cannot provide sustainable and stable incentive expectations；The targeting and dynamic adaptation of fiscal and taxation policies aiming at the real-digital integration are insufficient；Under the background of digitalization，it faces the dilemma of the coordination of international tax jurisdiction and the failure of cross-border tax collection and administration. Based on this，the focus of fiscal and tax policies to further promote the integration of data and reality on the CIIE platform in the future should be as follows：first，to improve the preferential system of CIIE；Second，optimize the mix of fiscal policy tools at CIIF to promote real-digital integration and coordinated development. Third，we will promote dynamic policy evaluation and feedback mechanisms to make policies more adaptable. Fourth，build a full-chain digital collection and management system，strengthen cross-department collaborative governance，and strengthen risk prevention and control；Fifth，we will promote synergy with international tax rules.
