Abstract: The Twentieth National Congress of the Communist Party of China proposed that high-quality development is the primary task of building a socialist modern country in an all-round way. On the new journey of Chinese path to modernization, we should focus on high-quality development, which means that high-quality development begins to enter the accelerated stage. In the new journey of Chinese path to modernization, efforts to promote high-quality development should have new logic: in the ideological logic, we should open up a new realm of ideological emancipation, master the scientific world outlook and methodology, and constantly promote high-quality transformation and development in the process of emancipating the mind. In terms of productivity logic, we should give play to the role of quality based productivity, and improve the overall efficiency and cooperation quality of productivity. In terms of dynamic logic, we should build an efficiency promotion mechanism for high-quality development, and improve labor productivity, capital productivity and total factor productivity through innovative development. In terms of growth logic, we should reshape the growth system of high-quality development and build a new system of conditions, processes, results and support for economic growth. In terms of institutional logic, improve the institutional arrangement for high-quality development, adapt to the institutional demand for high-quality development, and increase the institutional supply for high-quality development. In terms of market logic, we will promote the creation and development of high-quality large markets, promote the creation and development of domestic large markets, and open up to the outside world at a high level.
