This paper presents a simple and feasible method of estimating the means and covariances of system noise.The information about the means and covariances is derived from a suboptimal Karlman filter constructed accor- ding to the approximate statistics.An efficient algorithm is obtained through WLS (weighted least square) estimation by making use of the measurement residuals of the suboptimal Karlman filter.Simulations were presented to show the efficiency of the method.

提出了一种简单可行的估计动态系统噪声(动态噪声和测量噪声)的均值和协方差的方法.其主要思想是:从由近似的统计特性所形成的次佳卡尔曼滤波器中提取关于噪声均值和协方差的信息,以这个次佳卡尔曼滤波器的观测余差为数据用加权最小二乘方法来估计噪声的均值和协方差.最后用具体的仿真例子说明了这种方法的有效性.

For a class of partitioned mixed-effects linear model, a reduced model is introduced in order to obtain the best feasible linear unbiased estimator of a sub-vector of fixed effects. Some sufficient and necessary conditions for the estimators under the reduced model to be equal to the best linear unbiased estimte under the original model are obtained. To illustrate theoretical results, a practical example is also given.

Foreign direct investment (FDI) has been making important contribution to the economic growth of China, and foreign invested enterprises have become an indispensable part of economy system of China, so the environmental effect of FDI has been a focus issue. The paper focuses on how to estimate the transfer effect of FDI. Firstly, the paper gives the definition of pollution transfer effect. Secondly, it constructs the environmental input-output table with an emphasis on foreign invested enterprises, and then puts forward theoretical measuring formulas of transfer effect. Finally, considering data availability, the paper forwards two feasible methods to realize theoretical measuring formulas.

外商直接投资(简称FDI,下同)对中国的经济增长产生了重要的贡献,外资企业已经成为中国经济体系中不可缺少的部分,FDI的环境效应相应成为关注焦点。本文主要讨论如何估计FDI的转移效应。首先给出了污染转移效应的定义,其次构建了外资经济环境投入产出模型,并基于此提出转移效应的理论测度公式,最后,考虑到数据的可得性,提出了理论测度公式的两种可行估计方法。
