我国城乡教育差距与城乡居民教育投入差距的协整研究——基于1990～2005年的数据分析

The Co-integration Research on Educational Disparity and Investment Gap Between Urban and Rural Areas in China:Based on the Data of 1990～2005

本文从一种新的视角，也即从城乡居民教育投入差距的角度来分析我国的城乡教育差距，并基于1990-2005年的数据，利用协整理论对我国城乡教育差距与城乡居民教育投入差距的关系进行了研究。研究发现，我国当期城乡教育差距与当期城乡居民教育投入差距的对数之间存在着一种协整关系，这种关系是一种长期均衡关系。并且，在协整模型中，我国当期城乡居民教育投入差距对数值的系数为4．0％，这意味着当期城乡居民教育投入差距每提高l％，将使当期城乡教育差距扩大约4．0％。

From a new version-educational investment gap between urban and rural areas in China, this paper studies the educational disparity. Based on the data analysis of 1990-2005, this paper explores the relationship of educational disparity with investment gap between urban and rural areas in China using the Co-integration Theory. It finds out that it exists a kind of co-integration relationship between the logarithmic of educational disparity in current period and educational investment gap in current period and this kind of relationship is long and equilibrium Also, in co-integration model, the coefficient of the logarithmic of investment gap in current period is 4. 0%, this implies that the investment gap rises 1%, the educational disparity will enlarge about 4. 0%.
