First, the China Development Investment Fund has invested 360 billion yuan to promote infrastructure, because infrastructure is the basic project of the country, and only when the foundation is solid can there be room for development. For the further development of the country and society, we will invest heavily in infrastructure. At present, more than 400 basic projects have been supported, and with the further increase of investment in the future, the benefits will be wider and wider. Investment projects mainly include: renovation of old residential areas, maintenance and upgrading of expressway construction, upgrading and optimization of educational infrastructure, etc. Through this investment, housing conditions, travel and education will be further optimized. It can be seen that the role of this investment is to promote infrastructure construction.

Second, the national development and investment fund has invested 360 billion yuan to help economic development: because economic construction is based on infrastructure, only when infrastructure is stable can economic construction run smoothly. Moreover, by investing in infrastructure, the industrial scale has been expanded, so the economic scale has been expanded. The expansion of economic scale can increase infrastructure investment and realize a virtuous circle. So this kind of investment contributes to economic development.

Third, China Development Investment Fund has invested 360 billion yuan to attract private investment, because this fund investment is a state-led open-end fund investment. So private capital can also participate. Moreover, under the state-led construction investment, the investment risk will definitely be minimized and the development momentum will definitely be good, so it will attract private investment.
