美国著名农业经济学家舒尔茨曾有一个著名论断 :对影响农业经济发展的要素来说 ,土地的差异是不重要的 ,资本投入的多少是重要的 ,而素质的差异是最重要的。据测算 :美国农民教育程度指数每增加 1% ,农业劳动生产率则提高 0 .77%。据调查 :我国农民受教育的程度每增加 1年 ,平 Schultz, a well-known American agricultural economist, once made a famous conclusion: For the factors that affect the development of agricultural economy, the difference in land is unimportant. The amount of capital invested is important, and the difference in quality is the most important. It is estimated that for every 1% increase in the United States Farmers Education Level Index, agricultural labor productivity will increase by 0.77%. According to the survey, the level of education of peasants in our country increases by 1 year
