摘要
生产函数一直是经济学研究与应用中一个活跃的领域,文中就变替代弹性生产函数VES的两种情形给出经济预测模型。由于模型是非线性的,参数估计一般采用线性化的方法近似估计,在预测上多数情况存在较大的误差,所以文中利用非线性回归方法,非常好地给出最佳估计值,以使预测误差最小。
Production function is a hot topic in the study and application of economics.This paper gives two models of economic forecasting with Variable Elasticity of Substitution production function.Linearization is commonly used for the parameter estimate on account of the model being nonlinear,but this results in great error in most cases.Therefore,nonlinear regress method is adopted for a good estimate with least forecasting error.
