Abstract: With the development of economy and the increasing rate of population urbanization, financial support for the construction of urbanization proves to be particularly important. Three indicators of financial scale, financial structure and financial efficiency are chosen to measure the development level of financial market so as to establish a VAR model. Results show that the expansion of financial scale can significantly promote the development of population urbanization. The positive impact of financial efficiency and optimization of financial structure on population urbanization is manifested in the medium and long term.
