The rapid development of urbanization in China started in 1996 with two basic characteristics: the economic globalization and the transformation of economy. In the author's opinion, accumulation and diffusion are the two fundamental dynamic forms of the flow and the essential manifestation of the dynamics of urbanization. The author, by establishing an urbanization policy model of rural surplus labor force under indefinite situations, tries to explain the differences of the speed of urbanization between the period after the adoption of reform and open-up policy and the period of rapid development of urbanization, and comes to the conclusion that the latter period is the natural result of the combined force of the government and the market. Moreover, by making a metrological analysis on the numerical relationship between traditional industrialization and urbanization, the author promotes the opinion that the rapid development of urbanization is mainly stimulated by the tertiary industry. Then the author roughly estimates the industrial output value according to the import and export margin of industrial products and calculates the contribution of international trade to the development of urbanization.
