摘要本文运用超对数可变成本函数框架，定量研究1976- 1993年间公众研发活动对台湾稻米产业生产结构的影响。研究发现，自20世纪70年代中期以来，政府的研发活动在提高台湾稻米部门的生产力方面发挥了重要作用。此外，由于公共r&d活动导致的技术变革倾向于节省劳动力，使用中间投入和资本。这些偏差与这些要素投入的相对价格的变化是一致的，即节省相对昂贵的要素投入（劳动力）和使用相对便宜的要素投入（中间投入和资本）。从这个意义上说，公众R&E活动对要素市场的价格信号非常敏感。这一发现与希克斯诱导创新理论是一致的。
Using the translog variable cost function framework, this paper investigates quantitatively the impacts of the public R&E activities on the production structure of the Taiwanese rice industry for the 1976-93 period. It was found that the R&E activities by the government have played an important role in raising the productivity in the Taiwanese rice sector since the mid-1970s. Furthermore, technological change due to the public R&E activities has been biased toward saving labor, and using intermediate inputs and capital. These biases have been consistent with the changes in the relative prices of these factor inputs, i.e., saving a relatively more expensive factor input (labor) and using relatively less expensive factor inputs (intermediate inputs and capital). In this sense, the public R&E activities have been sensitive to the price signal of the factor markets. This finding is consistent with the Hicksian induced innovation theory.
