Research on Regional Economic Disparities, Employment Policy Supply and College Graduates' Spatial Employment Mobility Based on Computer Data Mining

Abstract

Against the background of unbalanced regional economic development in China, this study adopts computer data preprocessing and big data statistical analysis technology to explore the impact mechanism of regional economic disparities and employment policy supply on college graduates' spatial employment mobility, and clarifies the boundary conditions of policy effectiveness. Based on the micro-survey data of 7,862 college graduates in 31 provinces (autonomous regions and municipalities directly under the Central Government) and macroeconomic and policy data from 2010 to 2022, a comprehensive evaluation index system of regional economic disparities and employment policy supply intensity is constructed. With the help of computer econometric software, Binary logistic regression, moderating effect model, threshold effect model and heterogeneity analysis are used for empirical testing. The results show that: (1) Regional economic disparities and employment policy supply have a significant positive impact on college graduates' spatial employment mobility. Every 1% increase in the comprehensive score of regional economic disparities and employment policy supply increases the probability of graduates' cross-regional employment by 0.823% and 0.498% respectively. (2) Employment policy supply plays a positive moderating role in the relationship between regional economic disparities and graduates' spatial mobility, and the moderating effect is more significant in central and western regions. (3) There is a single threshold effect of employment policy supply. When the policy supply intensity exceeds 0.52, the promoting effect of regional economic disparities on graduates' spatial mobility is significantly enhanced from 0.486 to 1.023. (4) The impact of regional economic disparities and employment policy supply on graduates' spatial mobility has significant heterogeneity. The impact on master and doctoral graduates is stronger than that on undergraduate graduates, and the impact on graduates in central and western regions is stronger than that in eastern regions. This study enriches the theoretical framework of labor mobility research and provides targeted policy recommendations for optimizing the spatial allocation of college graduates and promoting regional coordinated development.
