The number of Sichuan’s towns is more than 1800 and the population exceeded half of the total. But the urbanization rate has lagged behind. This report shows that it is not biggest obstacle for the population urbanization to the Household Registration System but the economic bearing pressure and wide and deep poverty. From the industrial structure，the county already has the main features of the mid-industrialization. But further observation，because the supply of jobs and the contribution of public finances are relatively low，this industry structure is built on the basis of a low level. In the future，it is difficult to change the trend of net outflows of the majority population of the towns in short term，and may even exacerbate；the whole towns late in the demographic dividend，conditional towns will get the population quality effect；population flows distinctive features，the regional central town will be built.
