Abstract: Along with the rapid development of China's socialist modernization, the problem of migrant children gets more and more attention from the Party and the government. Through analyzing migrant children welfare policies in Heilongjiang province, and factors affecting the formulation and implementation of migrant children welfare policies, it can be seen that from the provincial level, Heilongjiang province lacks the geographical and economic advantages in attracting the migrant population, with no obvious attraction in terms of employment opportunities and policies and regulations. From the perspective of long-term development strategy for migrant children, it is suggested that top-level design of migrant children welfare policies should be conducted, with specific policy design for migrant children in terms of human capital investment, employment support, basic public services and social security; improve the implementation of migrant children's welfare policies and establish effective evaluation system,and construct a new welfare policy model for migrant children. It also meets the requirement of innovating social service management mode and building a service-oriented government at the current stage.

Key words: development, migrant children, migrant children welfare policies
