摘要
按实际教育成本计算,我国农村教育投资私人报酬率为:小学2.3%,初中2.1%,高中1.6%;教育投资内部报酬率(IRR)为:小学11.4%,初中13.7%,高中12.8%。预期收入每增加10%,农村教育投资内部报酬率分别增加:小学7.76%,初中7.99%,高中7.68%;私人教育投资内部报酬率对预期收入变化的灵敏性大于对投资成本变化的灵敏性,对小学教育投资变化的灵敏性大于其他受教育水平。农村劳动力受教育水平越高,其教育投资的边际收益越大。
This paper introduces two models of earning functions and internal rate of returns (IRR) used in estimating the private rate of returns to education. It outlines the estimates on the private rate of returns to education in rural Henan Province using the rural survey data from 1997 to 2001. Several microeconomic studies are described in more details illustrating the marginal income of education investment and the sensitivity of IRR to different levels of education investment. The concluding section discusses the results achieved:1. Calculated by earning functions, the private rate of returns to education for real education investment in rural China is 2.3% for primary schooling, 2.1% for lower secondary schooling, 1.6% for upper secondary schooling. Calculated by internal rate of returns, the IRR to education for real education investment in rural China is 11.4% for primary schooling, 13.7% for lower secondary schooling and 12.8% for upper secondary schooling. 2. The increase of 10% in expected earnings brings about an IRR increase of 7.76% for primary schooling, 7.99% for lower secondary schooling and 7.68% for upper secondary schooling; A decrease of 10% in the cost of primary schooling brings about an IRR increase of 8.3% for primary schooling, 4.75% for lower secondary schooling and 2.55% for upper secondary schooling; A decrease of 10% in the cost of lower secondary schooling results in an IRR increase of 3.11% for lower secondary schooling and 1.79% for upper secondary schooling. A decrease of 10% in the cost of upper secondary school brings about an IRR increase of 3.04%.3. The longer the schooling for rural labor, the higher are the marginal returns of education investment. The marginal returns of education investment for the rural workforce with more than 10 years of schooling is 3 times more than that of rural laborers with less than 1 year of schooling.It can be concluded from the above numbers that the private rate of returns to education in rural China is lower than that in other countries. Increasing the net income for farmers and decreasing the costs of education can help increase IRR to education investment in rural China. Furthermore, reforming traditional agriculture and improving the rural labor outflow from agriculture to other sectors like services and from rural areas to urban areas are the two major methods whereby the net income for farmers can increase. Increasing the current education investment for rural labor with higher education attainments can also help improve earnings for farmers effectively.
