With the development of urbanization,metropolises and megapolises are emerging.Urbanization is being completed with the driving force of capital;meanwhile,technology has achieved the quest of capital.In this thesis,in light of Henri Lefebvre’s ideology of technology rational critique,Chinese urban modernity issues under the perspective of technology rational critique were analyzed,including issues like eroded urban texture,urban mechanization,and urban segregation.The technology rational root of Chinese urban modernity issues was discussed from the turn of technical artifacts from design intention to application intention.In the end,possible methods to solve these Chinese urban modernity issues were illustrated based on Henri Lefebvre’s urban development theory.
