高等教育人口规模对经济增长的影响：地区异质性检验

近年来我国高等教育人口规模不断扩张，对经济社会产生了积极的影响。本文通过建立数理模型阐释了高等教育人口扩张对经济增长的影响机理，并使用1995年到2013年的省级面板数据考察了我国高等教育人口扩张对经济增长的作用，以及这一作用在不同地区的异质性。固定效应和随机效应模型表明，我国高等教育人口扩张促进了地区经济增长，且中西部地区的促进作用要大于东部地区。为了克服由反向因果引起的内生性偏误，本文使用2SLS方法进行了相应处理，结果依旧稳健。本文的研究对于制定高等教育发展的相关政策具有一定的参考意义。

Higher Education Extended Impact on Economic Growth:Regional Heterogeneity Test

In recent years,the scale of higher education in China is constant growing,and has had a significant impact on the economy and the society. The paper establishes a mathematical model illustrates the mechanism of the impact of higher edu-cation to economic growth,then using the provincial panel data from 1995 to 2013 examines the role of higher education ex-pansion on economic growth,and the regional heterogeneity of the impact. Fixed effects and random effects models show that China's expansion of higher education had played a significant role in promoting economic growth and more serious in central and western regions. In order to solve the endogenous problem caused by reverse causality ,we use 2SLS methods and the re-sult is still robust. This study has some reference value for develop policies about the development of higher education.
