Research On The Compilation Method Of Comparable Input-Output Sequences Table

The input-output method is a quantitative dependence relationship that reflects the input and output among various parts of the economic system.As a classic analytical method,it is widely used in various aspects,such as economic analysis and forecasting,policy simulation,and planning,etc.Meanwhile,it is constantly improved and developed during the practice.The input-output analysis is mainly realized through the input-output table which was created by Leontief in 1936 when he invented the Input Output Economics.In the past few decades,more than 100 countries and regions have compiled dozens of their own input-output tables.Since1987,China has compiled basic tables in the years with a mantissa of 2 or 7,and extension tables in the years with a mantissa of 5 or 0.So far,12 Chinese input-output tables have been published,and the provinces and municipalities have simultaneously compiled their own input and output tables.All these tables form a vast database.However,because of the difference in time and space,and the price,they cannot be directly compared.In order to carry out sequence analysis and expand the application of input-output analysis field,they need to be converted into a comparable table,forming a time series comparable table in the same space,or a different spatial comparable sequence table at the same time.The compilation of comparable tables has become an important topic of research for a long time.This article has carried on a more in-depth study of this.At present,the research on many methods of compilation can be divided into two categories: mathematical model method and "Li Liu Method".After studying more than ten kinds of mathematical model methods,the "Li Liu Method" was studied in depth,and under its guidance,the actual table was compiled,that is the comparable input and output tables in China from 1987 to 2015 was compiled.The time span is unprecedented.Onthis basis,the input-output theoretical price index method is proposed,the comparable input and output table is compiled.To this end,firstly,six basic tables and six extension tables published by the National Bureau of Statistics from 1987 to 2015 were reduced into “same departmentalization” of 31 departments.In order to form the time series of the same year,17 additional supplemental “Complete the Table” were prepared,thus forming29 Chinese input-output tables of 31 sector spanning 29 years;secondly,construct an input-output theoretical price index system,and study 6 price models according to the difference in social profit distribution;thirdly,the comparable input and output tables was compiled according to the input-output theoretical price index.
