Abstract: Capable of improving popular intelligence and skills, vocational and technical education can alleviate poverty and prevent its return. Based on the literature research and the logical deduction of economic theory, the supply of vocational and technical education can have a significant positive impact on prevention of poverty return. From the micro-individual level, vocational and technical education can improve the intelligence and skills of poor workers, create worker effect and allocation effect, and increase the value of human capital, which can play a great role not only in enhancing economic capacity and increasing labor productivity to provide opportunities for upward mobility but also in increasing the participation rate and wage level of non-agricultural labor to get more economic income and social resources. Thus it can ultimately improve the ability of blocking poor workers from returning to poverty. From the perspective of social regional economic development, vocational and technical education can enhance self-development ability of underdeveloped areas by improving their current human capital stock, increasing flow, and optimizing structure. On the other hand, increasing supply of vocational and technical education can more effectively allocate educational resources, promote economic growth and social development in underdeveloped areas, so as to ultimately enhance the ability of underdeveloped areas to prevent poverty return.

Key words: vocational and technical education supply, prevention of poverty return, mechanism
