China is currently in the era of education informatization 2.0, which has significant implications for the country's economic and social development. During the previous era, education informatization 1.0, the focus was on constructing and investing in informatization infrastructure. However, due to historical and economic factors, there were significant differences in the level of education informatization infrastructure construction across regions. This paper evaluates the construction of education informatization infrastructure in secondary schools during the education informatization 1.0 era, using a combination of data sources and analytical techniques. The results show that education informatization infrastructure construction has improved overall, with the central and eastern regions ahead of the western regions, also the central region has seen an increase in the ratio of both microcomputer room construction and voice classroom construction. However, the education informatization infrastructure construction in the western regions still requires improvement, which has significant implications for promoting regional equity in education and advancing China's education informatization agenda.
