Abstract: Technological progress will further improve the proportion of tertiary industry in the industrial structure, facilitating the improvement of urbanization rate. With application of 2005-2016 provincial panel data, the paper divides technological progress into technological efficiency changes and technological progress changes,compares and analyzes their differences of influence on urbanization, finding that technological efficiency changes and technological progress changes have significantly improved the urbanization rate while the improvement amplitude of technological efficiency changes is far smaller than that of technological progress changes;further analysis indicates that technological progress changes under agglomeration of tertiary industry exert greater and significant effects on urbanization while technological efficiency changes under non-agglomeration of tertiary industry exert small but significant effects on urbanization. Therefore, during the promotion process of urbanization, it is not only necessary to pay attention to the influence of technological efficiency changes and technological progress changes, but also necessary to attach importance to the influence differences between agglomeration of tertiary industry and non-agglomeration of tertiary industry.

Key words: urbanization;technological efficiency changes;technological progress, industrial agglomeration
