The Merger Of The Impact Analysis, The Price Of Various Departments

Input-output analysis was established by Prof. Wassily Leontief, who is the famous economist in America. Wassily Leontief published the first article "The quantitative relations of input-output in American economic system" about input-output in 1936, and from then on, input-output analysis was developed rapidly and comprehensively, and it had became an important analysis tool in the field of modern economic theory and practice.The sectors aggregation of input-output tables is an important problem in the studies of input-output analysis, where sectors aggregation means incorporation of national departments. It is more convenient to analyze and deal with the original data of input-output table when an input-output table with more than one-hundred departments becomes a new one with only several departments by aggregating, but on the other hands, in this process, the detailed information of the sub-departments in the original input-output table would be lost. So we should clear about that how to incorporate is reasonable and the best, how much the bias between new and original models is, and how to estimate the loss in the incorporation process. All of these are the core problems in the aggregation theory of input-output.The input-output analysis is a good method of the price forecast research. For one thing, the price problem's character is interactional and interrelated, for another thing, input-output analysis is good at dealing with interdependent problems. The price is an important problem, which referred abroad.It is not only a concemful matter in theory, but also a practical problem that affecting every department's economic profits.In the past, the researches of price paid main attentions to studying the influence of the price changes of one or more sectors on others by the use of input-output model, aiming to offer the basis of price decisions for the departments concerned. In this paper, the main aim is to discuss and research the influence of sectors aggregation on the product prices of every department, and present the corresponding mathematic...
