At the beginning of the new year，Bolsonaro was officially sworn in as the president of Brazil. The Bolsonaro government has made reforms and adjustments in its economic and social policies as the focus of its work in the early days of its administration. In terms of economic policy，the new government economic team will promote plans for pension reform，state-owned enterprise privatization and tax reform. In terms of social policy，the new government will make adjustments to social assistance programs，such as the Bolsa Família，the Fundamental Education Development and Maintenance Fund（Fundeb），and will also moderately tighten the money bag，cut public spending on social livelihood projects. Whether it is pension reform，state-owned enterprise privatization or tax reform，it is involved in a wide range of content，and it is still unclear whether the new government can smoothly promote the above reform plan. The expected effect of the reform is still unknown.
