高校扩招对大学生就业的影响:一个信号系统模型

A Study on the Impact of Enrollment Expansion in Colleges and Universities on College Graduates Employment:A Signal System Model

构建了一个基于信号理论的系统演变模型,将当前累积的未就业毕业生人数视为招生人数、岗位数量等输入信号的叠加响应,在此基础上研究了3种不同情形下高校扩招对大学生就业的影响。理论分析得到了市场均衡结果和有效教育就业系统的必要条件,数值分析发现累积未就业人数会受市场岗位数限制出现被动波动。最后基于模型的拓展形式,给出了改善当前大学生就业现状的有效建议。

This paper constructs a system evolution model based on the signal theory,regarding the current cumulative number of unemployed graduates as a superimposed response of input signals such as enrollment and job positions.Based on this,the impact of enrollment expansion in colleges and universities on college graduates employment is studied in three different situations.The theoretical analysis has obtained market equilibrium results and necessary conditions for an effective education and employment system.The numerical analysis has found that the cumulative number of unemployed graduates will experience passive fluctuations due to the limitations of market positions.Finally,based on the expanded form of the model,effective suggestions have been given for adjusting the structure of personnel training and promoting the matching of the job market.
