英文摘要：

Objectives： Multilevel model plays an important role in econometric analysis. Through the research on the statistical modeling of multilevel development model for analyzing high-level structural data, it expects to explore the theory and method of high-level hier-archical model establishing for nested structure data set. Research Methods： This paper summarizes the current research status about multilevel model, and then presents a high-level data structure of multilevel development model. Furthermore, we study model fitting effect by comparing the four, three, two level development models and the corresponding estimation results. At the same time, the paper empirically analyzes the nested data based on the farmers＇ income in western area of China. Research Findings： The results show that the significanees of parameters estimation for four level development model are better, and its model fitting effect is even more excellent. Research Innovations： It highlights that what are the advantages to establish a best statistical model for high-level hierarchical structural data set, and how to obtain useful results in applications. Research Value： We provide an effective sta-tistical modeling method of quantitative research for high-level complex structure data in socioeconomic fields.
