中国教育收益率的结构分析——基于技术溢出的视角

本文主要从技术溢出的视角出发，讨论了中国教育收益率的结构特征，特别是不同教育水平的教育收益率比较。我们认为，随着教育水平的不断提升，工人不但可以使用国内更为先进的技术，由于技术溢出的存在他们还能够借鉴国外技术来突破国内技术。按照这种思路，我们在Nel—son-Phelps模型的基础上进行了扩展，将收益率对教育年数的偏导数分解为”技术溢出效应”和”收益递减效应”，并且说明我国的高等教育的收益率可能会更高，而技术性职业的收益率的增加速度会更快。1989—2006年7期CHNS数据支持了我们模型的结论。

A Structural Analysis of Returns to Education in China——Based on the Sight of Technological Diffusion

The paper mainly discussed the characteristics of returns to education in China, especially the returns to different level of education from the view of technological diffusion. We argue that in China with the increase of education, the worker can not only use the more advanced technology in the nation, and can even borrow from abroad to exceed the existing top technology in the country, due to the existence of technological diffusion. According to this method we extended Nelson-Phelps model, and decompose the partial derivative of returns to education to the years of education into the “technological diffusion effect” and “decreasing returns effect”. The model predicts that in China the returns to education could increase with the education level, and the returns to education in more technological job will increase more. The seven wave CHNS data from 1989 to 2006 supported our conclusion.
