摘要
首先回顾了中国近20多年来农业技术进步贡献率测算的几种主要方法,包括CD生产函数法、索罗余值法、超越对数函数法和其它一些方法。接着从测算模型的选择、变量的取值以及最后测算的结果等方面对几种主要方法进行了比较与评析,最后是测算中国农业技术进步贡献率的一些结论和建议:方法的选择上,超越对数函数具有明显的优势;变量选取上,物质费用宜宏观取值;时间变量仍为技术进步的重要代理变量。
The paper reviews several main methods of quantitative evaluation of agro-technical progress contribution in China in the past twenty years as Copper-Douglas Production Function, Solow Surplus Value Algorithm Model, Translog Production Function and other methods. Then this paper gives these methods comments mainly on production model choosing, variable confining and results comparing. Finally, there are some conclusions and some advices to improve the methods of quantitative evaluation of agro-technical progress contribution in China： making Translog Production Function used widely, materials input macrochoosing and time variable as technical progress agent variable.
