Abstract: Winning the battle against poverty is an important task for building a moderately well-off society in all respects. The mechanism of poverty alleviation effect of informationization is discussed from the theoretical level in the paper. Then, the paper tests the rural poverty alleviation effect of informationization, by using unbalanced panel data of 273 prefecture-level cities,and carries out a comprehensive analysis of the regional differences of the rural poverty alleviation effect. The results show that informatization significantly reduces poverty levels in rural areas. However, there are still large regional differences in the rural poverty alleviation effect of informationization. Specifically, the rural poverty alleviation effect of informatization is not obvious in the eastern region,is more significant in the western region,while is the strongest in the central region. Therefore, it is necessary to increase innovation support in industries such as information and communication technology industries, with particular attention to support for rural areas; certain policies support should be given to the central and western regions in supporting the development of informatization, so as to maximize the poverty alleviation effect of informatization.

Key words: informatization, poverty alleviation effect, urban, regional difference
