Abstract: In the new era, digital technology is the new driving force which leads to the high-quality development of ideological and political education. The coupling of digital technology and ideological and political education in structure, function and value proves that it is suitable and feasible for its high-quality development in the digital era. While digital technology promotes the education's upgrading and effect, it also causes certain risks. First, the tension loss of digital embedment in ideological and political education brings about the wrong tendencies such as digital suspension, dependence, supremacy and so on. Second, the subject of ideological and political education shows the dissonance and alienation tendency of the relationship between human self, human beings, human beings and education, human beings and society. Third, the excessive collection and abuse of ideological and political education data brings risks and challenges such as data overload, privacy invasion and data security. Fourth, algorithm bias, information cocoon, algorithm black box and other problems are caused by improper algorithm. So some concrete solutions are suggested: deepen the understanding by clarifying the strategic positioning of digital technology empowerment; strengthen the digital literacy education by playing the educational value of ideological and political education; strengthen the digital technical specification by promoting the full release of technical potential energy.
