Shared prosperity contributes to economic growth, and the promotion of shared prosperity has far-reaching social implications. In the process of promoting shared prosperity, attention should be focused on the role of fi scal policy and its policy options. It is argued in the study that shared prosperity should not only achieve overall prosperity, but also attach great importance to the rational distribution of the income. To promote shared prosperity, we need to maintain macroeconomic stability and fair income distribution based on sustainable growth. We also need to ensure the distribution of income across groups by "raising the income of the low-level earners, extending the income of the medium-level earners, and limiting the income of the high-level earners", so as to achieve a balanced development in China's Northeastern, Eastern, Central, and Western regions, achieve rural general prosperity, and achieve common prosperity in terms of spiritual and material progress. The study suggests that we should actively expand and improve three major fi scal policies —the tax policy, expenditure policy, and social security policy so as to promote shared prosperity.
