This paper sums up and compares the relation and the characteristic of different index series which is suitable to National Accounts,then discusses the issue of dynamical harmonization of index series.as well as the main method to solve it.It analyzes emphatically the necessity and feasibleness about substituting fixed-base index with chained index,and then analyzes the shortcoming of Sauerbeck Index which is generally applied in the national accounts and the nature of Fisher’s Chained Index. Use the experience of SNA,European and American countries,which are good for constant-price GDP accounting,this paper puts forward that constructing Year-of-year(Y-o-y)indices and annual index separately,and the construction of two index series are relatively independent.With the“3-step strategy”.improve and perfect the system of GDP accounting with fixed-price in China.
Various economic coefficients are the foundation of the input-output method.Through direct and complete measure of interindustrial relations,this paper goes into construction,diversity and relationship of the indicators with relevant important coefficients,influence coefficients and inducing coefficients,then elucidates its economic meanings and limitations.This paper calculates relevant indicator value with 1997 Input-Output Table of China,and discusses some problems about its application.It tries to enhance and perfect the application of input-output analysis.This paper concludes:the system of interindustrial relations indices in the Input-Output needs to be improved.In the respect of explaining economic phenomenon,the weighted influence coefficient and weighted inducing coefficient are better than the simple ones,at least are the helpful supplement of the latter.
