本研究提出了一个应用的广义误差修正模型（GECM）的异质要素需求的基础上的二次成本函数。使用1976-1995年期间26个西德制造业的数据，结果表明，不太通用的规格，如部分调整和静态AR（1）模型被拒绝。此外，不同技能类别的短期和长期劳动力需求都没有弹性。非技术工人的工资弹性在绝对值上比中等技术工人稍高。需求从非熟练劳动力转移的一小部分原因可以用中间材料和非熟练劳动力之间的可替代性关系来解释。在所观察到的向高技能劳动力转移的情况中，有6%至13%可以用资本积累来解释。
This study presents an application of the Generalized Error Correction Model (GECM) for heterogeneous factor demands based on the quadratic cost function., Using data for 26 West German manufacturing industries over the period 1976-1995, it turns out that less general specifications such as the partial adjustment and the static AR(1) model are rejected., Furthermore, both short-run and long-run labour demands of different skill classes are inelastic., Unskilled labour is found to have a somewhat higher wage elasticity in absolute terms than medium-skilled labour., A small part of the shift in demand away from unskilled labour can be explained by the substitutability relationship between intermediate materials and unskilled labour., Between 6 and 13 percent of the observed shift towards high-skilled labour can be explained by capital accumulation.,
