The deep application of artificial intelligence has become the core driving force for the digital transformation of early childhood education. The digital and intelligent literacy of early childhood teachers is the core prerequisite for achieving a deep integration of AI and early childhood education and conducting AI-based early childhood education. Based on the relevant research results of artificial intelligence education in early childhood education, this study clarifies the development laws of the digital and intelligent literacy of early childhood teachers in the era of artificial intelligence from three dimensions: value, internalization, and practical logic. It analyzes the four practical dilemmas existing in the current development of teachers' digital and intelligent literacy, namely, target misalignment, hierarchical discontinuity, insufficient support, and lack of motivation. Finally, it proposes systematic optimization paths from four aspects: target system, content framework, ecosystem construction, and motivation stimulation. The research aims to enrich the theoretical system of early childhood teachers' professional development and provide practical references for the improvement and upgrading of teachers' digital and intelligent literacy in the new era.
