中文摘要：

本文基于协整理论，利用我国1978—2009年间的数据估算了我国教育投资对三次产业的影响。结果表明：从长期来看，教育投资对三次产业具有显著的促进作用，这种促进作用存在滞后期。国家财政用于教育的支出每增长1％，国内生产总值增长1．185％，其中，第一产业增加值增长0．461％，第二产业增长1．400％，第三产业增长1．216％。它们的滞后期依次是10年、9年、11年、10年。但从短期来看，教育投资对三次产业的影响都是不显著的。

英文摘要：

The paper calculates the effect of China educational investment on three industries in the period 1978-2009 based on the co-integration theory. From the empirical results, we can infer that the stimulative effect of educational investment on three industries is statistically significant in the long term and there is a lag period. When government expenditure on education is increased every one percentage by itself, GDP increases 1.185 percentage, the value-added of Primary Industry increases 0.461 percentage, the value-added of Secondary Industry increases 1.400 percentage, the value-added of Tertiary Industry increases 1.216 percentage, and their lag periods are ten years, nine years, eleven years, ten years in turn. But the effect of educational investment on three industries is not statistically significant in the short term.
