英文文献摘要：
A cost function approach of induced innovation is used to measure the biases in U.S. agricultural technology between 1948-1994. The results show significant labor-saving, capital-using technical change. Focusing on the impact of migration policy on labor-saving technology, a simulation of different rates of labor-saving technical change is conducted. The simulation shows decreases in elasticity of labor demand and demand quantity, and an increase in wage rate as technology becomes more labor-saving.

诱导创新的成本函数方法被用来衡量1948-1994年间美国农业技术的偏差。研究结果显示出显著的省力、资本利用技术变革。针对移民政策对节省劳动力技术的影响，模拟了不同的节省劳动力技术变化率。模拟结果表明，随着技术的改进，劳动力需求弹性和需求量降低，工资率提高。
