拉氏指数

首先，论文从编制基本生活费用指数的理论研究入手，根据生活费用指数理论，在位似偏好的条件下，可以利用拉氏价格指数和帕氏价格指数来近似估计生活费用价格指数。

According to the theory of living cost index , in the condition of homothetic preference , Laspeyres and Paasche price index can be used to estimate the living cost index .

在指数形式上本文对传统方法进行了改进，采用拉氏价格指数和帕氏价格指数构成的区间，对基本生活费用价格指数进行估计，这也是本文的创新之一。

On the collection of the form , this paper changes the traditional way to use the range between Laspeyres and Paasche price index to estimate the price index of basic living cost , which is one of the innovations in this paper .
