【摘要】:首次在随机前沿模型中同时引入因变量间(或双边误差间)和技术效率间的空间相关性并构造了双重滞后随机前沿模型,使用极大似然估计方法和JLMS方法得出参数和技术效率的估计。蒙特卡罗模拟表明:忽略技术效率的空间相关性,参数估计和技术效率的估计均表现欠佳。本研究能以较高的精度估计参数和技术效率。随着样本容量的增加,估计效果更优。
[Abstract]:For the first time, the spatial correlation between dependent variables (or bilateral errors) and technical efficiency is introduced into the stochastic frontier model for the first time, and a double lag stochastic frontier model is constructed.The maximum likelihood estimation method and JLMS method are used to estimate the parameters and technical efficiency.Monte Carlo simulation shows that the spatial correlation of technical efficiency and the estimation of parameters and technical efficiency are not good.This study can estimate parameters and technical efficiency with high accuracy.With the increase of sample size, the effect of estimation is better.
