In today's economic globalization, education plays an important role in public management. It can not only improve the overall quality of human society, but also a way of cultural communication. This paper mainly introduces the concept of public management and the characteristics of educational economy, and expounds the calculation method of educational economic contribution rate. Then, through investigation and research, this paper finds that there are many factors affecting educational equity. The most direct reason is that the government and schools lack reasonable planning for private schools, resulting in imperfect school facilities and high employment pressure on students; on the other hand, the rapid economic development leads to the shortage of talent supply, which leads to the decline of education quality. At the same time, based on the survey results, this paper finds that the penetration rate of primary and secondary education in Uzbekistan has increased significantly, the cultural level of adults and youth has improved, and gender equality in primary and secondary education opportunities.
