During the 13th Five-Year Plan period，the eastern region leads the country in the process of modernization，which is characterized by sustained per capita income growth，accelerated industrial upgrading，gradually narrowing the urban-rural gap，and notable progress in achieving common prosperity. But there are also problems，such as unbalanced economic development，insufficient innovation in key technologies，lagging reform in key areas，large income gaps，and difficulty in coordinating regional environmental governance. In the period of the 14th Five-Year Plan，it is necessary to further promote market-oriented reform，climb the global value chain，develop the economy of the metropolitan area，and reform the income distribution system，which provides a useful reference for the modernization of the whole country.
