我国农业公共科研投资的配置:要素稀缺性技术诱导假说的检验

Public Research Investment Allocation in Chinese Agriculture:A Test of Factor Scarcity Induced Invention Hypotheses

本文首先推导出了要素稀缺性技术诱导假说的数学形式,然后在此基本上充分考虑我国农业公共科研投资配置的“基数”行为,将现有的检验模型拓展为三元计量模型,并采用我国30个省市的综列数据进行了实证分析。研究结果显示,近年来,我国农业公共科研投资的分配基本上以节约耕地面积技术为主要投入方向,这与要素稀缺性技术诱导假说基本一致。这个结论的理论意义是可将技术诱导性假说扩展到不完全市场经济下的技术创新,其政策含义是我国农业公共科研投资分配的倾斜对象依然是以提高土地生产率为目标的技术创新。

The paper deduces the mathematic form of factor scarcity induced invention hypotheses at first, then taking the allocation behavior of public investment of Chinese agricultural research into account, develops binary test model into ternary test model, finally applies panel data of Chinese agricultural research in vestment to do experience analysis. The results show that the allocation of public investment of Chinese agricultural research is consistent with factor scarcity induced invention hypotheses.
